Description

FIELD OF THE INVENTION
The invention relates in general to heterocyclics and related compounds and their broad-spectrum utility, e.g., in inhibiting heat shock protein 90 (HSP90) to thereby treat or prevent HSP90-mediated diseases.
BACKGROUND
HSP90s are ubiquitous chaperone proteins that are involved in folding, activation and assembly of a wide range of proteins, including key proteins involved in signal transduction, cell cycle control and transcriptional regulation. Researchers have reported that HSP90 chaperone proteins are associated with important signaling proteins, such as steroid hormone receptors and protein kinases, including, e.g., Raf-1, EGFR, v-Src family kinases, Cdk4, and ErbB-2 ( Buchner J. TIBS 1999, 24, 136-141; Stepanova, L. et al. Genes Dev. 1996, 10, 1491-502; Dai, K. et al. J. Biol. Chem.1996, 271, 22030-4). Studies further indicate that certain co-chaperones, e.g., HSP70, p60/Hop/Sti1, Hip, Bag1, HSP40/Hdj2/Hsj1, immunophilins, p23, and p50, may assist HSP90 in its function (see, e.g., Caplan, A. Trends in Cell Biol.1999, 9, 262-68).
Ansamycin antibiotics, e.g., herbimycin A (HA), geldanamycin (GM), and 17-allylaminogeldanamycin (17-AAG) are thought to exert their anticancerous effects by tight binding of the N-terminus pocket of HSP90, thereby destabilizing substrates that normally interact with HSP90 (Stebbins, C. et al. Cell1997, 89, 239-250). This pocket is highly conserved and has weak homology to the ATP-binding site of DNA gyrase (Stebbins, C. et al., supra; Grenert, J.P. et al. J. Biol. Chem. 1997,272,23843-50). Further, ATP and ADP have both been shown to bind this pocket with low affinity and to have weak ATPase activity (Proromou, C. et al. Cell 1997, 90, 65-75; Panaretou, B. et al. EMBO J. 1998, 17; 4829-36). In vitro and in vivo studies have demonstrated that occupancy of this N-terminal pocket by ansamycins and other HSP90 inhibitors alters HSP90 function and inhibits protein folding. At high concentrations, ansamycins and other HSP90 inhibitors have been shown to prevent binding of protein substrates to HSP90 (Scheibel, T.H. et al. Proc. Natl. Acad. Sci. USA 1999, 96, 1297-302; Schulte, T. W. et al. J. Biol. Chem. 1995, 270, 24585-8; Whitesell, L., et al. Proc. Natl. Acad. Sci. USA 1994, 91, 8324-8328). Ansamycins have also been demonstrated to inhibit the ATP-dependent release of chaperone-associated protein substrates (Schneider, C.L. et al. Proc. Natl. Acad. Sci., USA 1996, 93, 14536-41; Sepp-Lorenzino et al. J Biol. Chem. 1995, 270, 16580-16587). In either event, the substrates are degraded by a ubiquitin-dependent process in the proteasome (Schneider, C. L., supra; Sepp-Lorenzino, L., et al. J. Biol. Chem. 1995, 270, 16580-16587; Whitesell, L. et al. Proc. Natl. Acad. Sci. USA 1994, 91, 8324-8328).
HSP90 substrate destabilization occurs in tumor and non-transformed cells alike and has been shown to be especially effective on a subset of signaling regulators, e.g., Raf (Schulte, T. W. et al. Biochem. Biophys. Res. Commun. 1997, 239, 655-9; Schulte, T. W., et al. J. Biol. Chem. 1995, 270, 24585-8), nuclear steroid receptors (Segnitz, B.; U. Gehring J. Biol. Chem. 1997, 272,18694-18701; Smith, D. F. et al. Mol. Cell. Biol. 1995, 15, 6804-12), v-Src (Whitesell, L., et al. Proc. Natl. Acad. Sci. USA 1994, 91, 8324-8328) and certain transmembrane tyrosine kinases (Sepp-Lorenzino, L. et al. J. Biol.Chem. 1995, 270, 16580-16587) such as EGF receptor (EGFR) and HER2/Neu (Hartmann, F., et al. Int. J. Cancer 1997, 70, 221-9 ; Miller, P. et al. Cancer Res. 1994, 54, 2724-2730; Mimnaugh, E. G., et al. J. Biol. Chem. 1996, 271, 22796-801; Schnur, R. et al. J. Med. Chem. 1995, 38, 3806-3812), CDK4, and mutant p53. Erlichman et al. Proc. AACR 2001, 42, abstract 4474. The ansamycin-induced loss of these proteins leads to the selective disruption of certain regulatory pathways and results in growth arrest at specific phases of the cell cycle (Muise-Heimericks, R. C. et al. J. Biol. Chem. 1998, 273, 29864-72), and apoptosis, and/or differentiation of cells so treated (Vasilevskaya, A. et al. Cancer Res., 1999, 59, 3935-40). Ansamycins thus hold great promise for the treatment and/or prevention of many types of cancers and proliferative disorders, and also hold promise as traditional antibiotics. However, their relative insolubility makes them difficult to formulate and administer, and they are not easily synthesized and currently must, at least in part, be generated through fermentation. Further, the dose limiting toxicity of ansamyins is hepatic.
In addition to anti-cancer and antitumorgenic activity, HSP90 inhibitors have also been implicated in a wide variety of other utilities, including use as anti-inflammation agents, anti-infectious disease agents, agents for treating autoimmunity, agents for treating stroke, ischemia, multiple sclerosis, cardiac disorders, central nervous system related disorders and agents useful in promoting nerve regeneration (See, e.g., Rosen et al. WO 02/09696 ( PCT/US01/23640 ); Degranco et al. WO 99/51223 ( PCT/US99/07242 ); Gold, U.S. Patent 6,210,974 B1 ; DeFranco et al., US Patent 6,174,875 . Overlapping somewhat with the above, there are reports in the literature that fibrogenetic disorders including but not limited to scleroderma, polymyositis, systemic lupus, rheumatoid arthritis, liver cirrhosis, keloid formation, interstitial nephritis, and pulmonary fibrosis also may be treatable with HSP90 inhibitors. Strehlow, WO 02/02123 ( PCT/US01/20578 ). Still further HSP90 modulation, modulators and uses thereof are reported in Application Nos. PCT/US03/04283 , PCT/US02/35938 , PCT/US02/16287 , PCT/US02/06518 , PCT/US98/09805 , PCT/US00/09512 , PCT/US01/09512 , PCT/US01l23640 , PCT/US01/46303 , PCT/US01/46304 , PCT/US02/06518 , PCT/US02/29715 , PCT/US02/35069 , PCT/US02/35938 , PCT/US02/39993 , 60/293,246 , 60/371,668 , 60/335,391 , 60/128,593 , 60/337,919 , 60/340,762 , 60/359,484 and 60/331,893 .
Recently, purine derivatives showing HSP90 inhibitory activity have been reported, e.g., in PCT/US02/35069 and PCT/US02/36075 . Purine moieties are well accepted bioisosteres for a variety of ATP-dependent molecular targets, see, JP 10025294 ; US Patent 4,748,177 ; US Patent 4,772,606 ; US Patent 6,369,092 ; WO 00/06573 ; WO 02/055521 ; WO 02/055082 ; WO 02/055083 ; European Patent 0178178 ; Eur. J Med. Chem, 1994, 29(1), 3-9; and J. Het. Chem. 1990, 27(5), 1409. However, compounds having the desired potency, selectivity and pharmaceutical properties required for effective HSP90 inhibition in vivo have not been reported. Therefore, a need remains for additional novel and potent HSP90 inhibitors that meet the demanding biological and pharmaceutical criteria required to proceed towards human clinical trials.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS I. DEFINITIONS
A "pharmaceutically acceptable derivative or prodrug" means any pharmaceutically acceptable salt, ester, salt of an ester or other derivative of a compound of this invention, which, upon administration to a recipient, is capable of providing, either directly or indirectly, a compound of this invention or a pharmaceutically active metabolite or residue thereof. Particularly favored derivatives or prodrugs are those that increase the bioavailability of the compounds of this invention when such compounds are administered to a patient (e.g., by allowing orally administered compound to be more readily absorbed into blood) or which enhance delivery of the parent compound to a biological compartment (e.g., the brain or lymphatic system).
A "pharmaceutically acceptable salt" may be prepared for any compound of the invention having a functionality capable of forming a salt, for example, an acid or base functionality. Pharmaceutically acceptable salts may be derived from organic or inorganic acids and bases. Compounds of the invention that contain one or more basic functional groups, e.g., amino or alkylamino, are capable of forming pharmaceutically acceptable salts with pharmaceutically acceptable organic and inorganic acids. These salts can be prepared in situ during the final isolation and purification of the compounds of the invention, or by separately reacting a purified compound of the invention in its free base form with a suitable organic or inorganic acid, and isolating the salt thus formed. Examples of suitable acid salts include acetate, adipate, alginate, aspartate, benzoate, benzenesulfonate, bisulfate, butyrate, citrate, camphorate, camphorsulfonate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptanoate, glycerophosphate, glycolate, hemisulfate, heptanoate, hexanoate, hydrochloride, hydrobromide, hydroiodide, 2-hydroxyethanesulfonate, lactate, maleate, malonate, methanesulfonate, 2-napthalenesulfonate, nicotinate, nitrate, oxalate, palmoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, salicylate, succinate, sulfate, tartrate, thiocyanate, tosylate and undecampate. Other acids, such as oxalic, while not in themselves pharmaceutically acceptable, may be employed in the preparation of salts useful as intermediates in obtaining the compounds of the invention and their pharmaceutically acceptable acid addition salts. See, e.g., Berge et al. "Pharmaceutical Salts", J. Pharm. Sci. 1977, 66:1-19.
Compounds of the present invention that contain one or more acidic functional groups are capable of forming pharmaceutically acceptable salts with pharmaceutically acceptable bases. The term "pharmaceutically acceptable salts" in these instances refers to the relatively non-toxic, inorganic and organic base addition salts of compounds of the present invention. These salts can likewise be prepared in situ during the final isolation and purification of the compounds, or by separately reacting the purified compound in its free acid form with a suitable base, such as the hydroxide, carbonate or bicarbonate of a pharmaceutically acceptable metal cation, with ammonia, or with a pharmaceutically acceptable organic primary, secondary or tertiary amine. Representative alkali or alkaline earth salts include the lithium, sodium, potassium, calcium, magnesium, and aluminum salts and the like. Illustrative examples of some of the bases that can be used include sodium hydroxide, potassium hydroxide, choline hydroxide, sodium carbonate, N+(C1-4 alkyl)4, and the like. Representative organic amines useful for the formation of base addition salts include ethylamine, diethylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine and the like. This invention also envisions the quaternization of any basic nitrogen-containing groups of the compounds disclosed herein. Water or oil-soluble or dispersible products may be obtained by such quaternization. See, for example, Berge et al., supra.
Pharmaceutically acceptable prodrugs of the compounds of this invention include, but are not limited to, esters, carbonates, thiocarbonates, N-acyl derivatives, N-acyloxyalkyl derivatives, quaternary derivatives of tertiary amines, N-Mannich bases, Schiff bases, aminoacid conjugates, phosphate esters, metal salts and sulfonate esters.
Suitable positions for derivatization of the compounds of the invention to create "prodrugs" include but are not limited, 2-amino substitution. Those of ordinary skill in the art have the knowledge and means to accomplish this without undue experimentation. Various forms of prodrugs are well known in the art. For examples of such prodrug derivatives, see, e.g.,

Some of the compounds of the present invention may contain one or more chiral centers and therefore may exist in enantiomeric and diastereomeric forms. The scope of the present invention is intended to cover all isomers per se, as well as mixtures of cis and trans isomers, mixtures of diastereomers and racemic mixtures of enantiomers (optical isomers) as well. Further, it is possible using well known techniques to separate the various forms, and some embodiments of the invention may feature purified or enriched species of a given enantiomer or diasteriomer.
A "pharmacological composition" refers to a mixture of one or more of the compounds described herein, or pharmaceutically acceptable salts thereof, with other chemical components, such as pharmaceutically acceptable carriers and/or excipients. The purpose of a pharmacological composition is to facilitate administration of a compound to an organism.
The phrase "pharmaceutically acceptable carrier" as used herein means a pharmaceutically-acceptable material, composition or vehicle, such as a liquid or solid filler, diluent, excipient, solvent or encapsulating material, involved in carrying or transporting the subject agent from one organ, or portion of the body, to another organ, or portion of the body. Each carrier must be "acceptable" in the sense of being compatible with the other ingredients of the formulation and not injurious to the patient. Some examples of materials which can serve as pharmaceutically-acceptable carriers include: (1) sugars, such as lactose, glucose and sucrose; (2) starches, such as corn starch and potato starch; (3) cellulose, and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; (4) powdered tragacanth; (5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository waxes; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; (10) glycols, such as propylene glycol; (11) polyols, such as glycerin, sorbitol, mannitol and polyethylene glycol; (12) esters, such as ethyl oleate and ethyl laurate; (13) agar; (14) buffering agents, such as magnesium hydroxide and aluminum hydroxide; (15) alginic acid; (16) pyrogen-free water; (17) isotonic saline; (18) Ringer's solution; (19) ethyl alcohol; (20) phosphate buffer solutions; and (21) other non-toxic compatible substances employed in pharmaceutical formulations. A physiologically acceptable carrier should not cause significant irritation to an organism and does not abrogate the biological activity and properties of the administered compound.
An "excipient" refers to an inert substance added to a pharmacological composition to further facilitate administration of a compound. Examples of excipients include but are not limited to calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils and polyethylene glycols.
A "pharmaceutically effective amount" means an amount which is capable of providing a therapeutic and/or prophylactic effect. The specific dose of compound administered according to this invention to obtain therapeutic and/or prophylactic effect will, of course, be determined by the particular circumstances surrounding the case, including, for example, the specific compound administered, the route of administration, the condition being treated, and the individual being treated. A typical daily dose (administered in single or divided doses) will contain a dosage level of from about 0.01 mg/kg to about 50-100 mg/kg of body weight of an active compound of the invention. Preferred daily doses generally will be from about 0.05 mg/kg to about 20 mg/kg and ideally from about 0.1 mg/kg to about 10 mg/kg. Factors such as clearance rate, half-life and maximum tolerated dose (MTD) have yet to be determined but one of ordinary skill in the art can determine these using standard procedures.
In some method embodiments, the preferred therapeutic effect is the inhibition, to some extent, of the growth of cells characteristic of a proliferative disorder, e.g., breast cancer. A therapeutic effect will also normally, but need not, relieve to some extent one or more of the symptoms other than cell growth or size of cell mass. A therapeutic effect may include, for example, one or more of 1) a reduction in the number of cells; 2) a reduction in cell size; 3) inhibition (i.e., slowing to some extent, preferably stopping) of cell infiltration into peripheral organs, e.g., in the instance of cancer metastasis; 3) inhibition (i.e., slowing to some extent, preferably stopping) of tumor metastasis; 4) inhibition, to some extent, of cell growth; and/or 5) relieving to some extent one or more of the symptoms associated with the disorder.
As used herein, the term IC50 refers to an amount, concentration or dosage of a particular test compound that achieves a 50% inhibition of a maximal response in an assay that measures such response. In some method embodiments of the invention, the "IC50" value of a compound of the invention can be greater for normal cells than for cells exhibiting a proliferative disorder, e.g., breast cancer cells. The value depends on the assay used.
By a "standard" is meant a positive or negative control. A negative control in the context of HER2 expression levels is, e.g., a sample possessing an amount of HER2 protein that correlates with a normal cell. A negative control may also include a sample that contains no HER2 protein. By contrast, a positive control does contain HER2 protein, preferably of an amount that correlates with overexpression as found in proliferative disorders, e.g., breast cancers. The controls may be from cell or tissue samples, or else contain purified ligand (or absent ligand), immobilized or otherwise. In some embodiments, one or more of the controls may be in the form of a diagnostic "dipstick."
By "selectively targeting" is meant affecting one type of cell to a greater extent than another, e.g., in the case of cells with high as opposed to relatively low or normal HER2 levels.

As mentioned above, the events (1) assembly of the bicyclic system (2) appendage of the R5-R4- moiety, and (3) further elaboration of the ring systems do not necessarily have to be made in the sequence (1)-(2)-(3), and it may be beneficial to proceed in a different sequence.
Method 4.1.
Scheme 8 shows a synthesis in which the order of events is not (1)-(2)-(3), but is (2)-(1)-(3). First R5 is appended via an aromatic nucleophilic substitution, then the bicyclic system is constructed, and finally it is elaborated.

Method 4.3
For illustrative purposes, Scheme 10 shows a putative synthesis in which the order of events is not (1)-(2)-(3), but is (1)-(3)-(2)-(3). First the bicyclic ring is constructed, then it is elaborated, then the R4-R5 moiety is appended, and finally the bicyclic ring system is further elaborated (deprotection).

1. Method 1: From purines:
The compounds of Formula IIC (see, Scheme 12) can be synthesized from the commercially available starting heterocycle, for example compounds of Formula 2 where R6 is -Cl, -Br or -OH, R7 is -NH2 and R8 is -H are commercially available from Aldrich, AlfaAesar, etc. Accordingly, Formula 2 can be alkylated in the presence of a base such as K2CO3, NaH, Cs2CO3, DBU etc. with/without the presence of halide such as NaI, KI, (Bu)3NI etc., and in a polar solvent such as DMF, THF, DMSO etc. using electrophiles such as L1-R4-R5 where -L1 is a leaving group. Leaving groups include but are not limited to, e.g., halogen, triflate, tosylate , mesylate etc. See Kasibhatla, PCT publication number WO 03/037860 . Compounds of Formula I, wherein R1 is -OH can be converted to halides using standard conditions POCl3, POBr3 etc. with/without the presence of base such as Et3N, N,N-diethylaniline, (i-pr)2NEt etc. in polar solvents such as CH3CN, CH2Cl2 etc.
The compounds of Formula IIC, wherein R1 is -OR11, -SR11, or -NHR8 where R11 is alkyl, R8 is hydrogen, lower alkyl, lower aryl, or -C(O)R9, where R9 is lower alkyl, lower aryl, lower heteroaryl, -NR10R10, or -OR11, where R10 is independently hydrogen or lower alkyl, can be prepared from compounds of Formula IIC wherein R1 is halogen reacting with HOR11, HSR11 or NH2R8 in presence of a base such as K2CO3 or NaH and a polar solvent such as DMF or THF. Compounds of Formula IIC where R8 is -C(O)R9 can be prepared when R1 is hydroxyl by simple acylation.
Compounds of Formula IIC where R1 is alkyl can be prepared from compounds of Formula II where R1 is halogen and trialkyl aluminum or dialkyl zinc. (See Holy, J. Med. Chem. 1999, 42, 2064).
R5 especially when it is aryl or heteroaryl, can be further modified as needed, for example by halogenation, nitration, palladium coupling of halogen, Friedel-Crafts alkylation/acylation, etc. or these modifications can also be done before alkylation, see Jerry March, Advanced Organic Chemistry. The heteroaromatic rings can also be oxidized to their corresponding N-oxides using various oxidizing agents such as H2O2, O3, MCPBA etc. in polar solvents such as CH2Cl2, CHCl3, CF3COOH etc. See Jerry March, Advanced Organic Chemistry, 4th edition, Chapter 19.
Compounds of Formula IIC where R3 is halogen, can be prepared from Formulae 1 or 2 using halogenating agents such as Br2, NBS, NCS, NIS etc. in polar solvents such as DMF, water, or suitable buffer solution. See Herdewijn, J. Med. Chem. 1995, 38, 3838. Alternatively, compounds of Formula 2 where R8 is iodo can also be made using procedures known in the literature, e.g., Burger, J. Org.

Accordingly, reaction of commercially available compounds of Formula 5, where R16 is hydrogen or -NO2, (see J. Chem. Soc. 1962, 4186, for the preparation of R16 = -NO2 compound) with NH2-R4-R5 in solvents such as EtOH, BuOH etc. in presence of organic bases such as Et3N, (i-pr)2NEt etc. followed by nitrosation (when R16 = -H) using nitrous acid, then reduction with sodium dithionite or Zn/HCOOH etc. of Formula 6 (R16 = -NO or -NO2) to yield compounds of Formula 6 where R16 is -NH2. Condensation of Formula 6, where R16 is -NH2 using standard conditions such as triethylorthoformate, formic acid, cyanogenbromide etc. as described in J. Chem. Soc. 1963, 4186; Sircar, U.S. Patent 4,748,177 , 1988 ; and Dang, WO 98/39344 , followed by reaction with POCl3 to give compounds of Formula II, Scheme 13. These compounds of Formula IIC can be further modified as necessary.
Similarly, compounds of Formula IIC can also be synthesized from Formula 7, 2-amino-4, 6-dichloro pyrimidine (see Scheme 14).

Leaving groups include but are not limited to, e.g., halogen, triflate, tosylate, mesylate etc. to give compounds of Formula 10. The ring closure can be achieved using many methods reported in the literature, Alhede, J. Org. Chem., 1991, 2139 and references cited therein to give guanines of Formula II, wherein R1 is OH. These compounds can be converted to the compounds of Formula II, wherein R1 is Cl using POCl3 as described earlier. Advantageously, these steps can be reversed as shown in Scheme 16 via Formula 11. Alternately, we can also construct these 2-aminopyrimidine rings from Formula 4, wherein R14 is -OH or halide, R13 is -C(O)OEt and R15 is -H by reacting with guanidine hydrochloride as described in Chowdhury, J.

Examples of modifications are suggested in Scheme 21.
4. Permutations of the order of events
As mentioned above, the events (1) assemby of the bicyclic system (2) appendage of the R5-R4- moiety, and (3) further elaboration of the ring systems do not necessarily have to be made in the sequence of (1)-(2)-(3), and it may be beneficial to proceed in a different sequence.
For illustrative purposes, Scheme 6 shows a putative synthesis in which the order of events is not (1)-(2)-(3), but is (1)-(3)-(2).
First the bicyclic system is prepared, then it is elaborated, and finally R5 is appended via an alkylation.
For illustrative purposes, Scheme 23 shows a putative synthesis in which the order of events is not (1)-(2)-(3), but is (2)-(1)-(3). First the R5 group is appended to a pyrimidine via an aromatic nucleophilic substitution, then the bicyclic ring system is constructed, and finally a series of functional group interconversions yields the compound of Formula IIIA.
Also, if R5 is, for instance, a pyridine, it can be converted to a N-oxide either before or after alkylation.

For example, the therapeutic or pharmaceutical compositions of the invention can be administered locally to the area in need of treatment. This may be achieved by, for example, but not limited to, local infusion during surgery, topical application, e.g., cream, ointment, injection, catheter, or implant, said implant made, e.g., out of a porous, non-porous, or gelatinous material, including membranes, such as sialastic membranes, or fibers. The administration can also be by direct injection at the site (or former site) of a tumor or neoplastic or pre-neoplastic tissue.
Still further, the compounds or compositions of the invention can be delivered in a vesicle, e.g., a liposome (see, for example, Langer, Science 1990, 249, 1527-1533; Treat et al., Liposomes in the Therapy of Infectious Disease and Cancer, Lopez-Bernstein and Fidler, Ed., Liss, N.Y., pp. 353-365, 1989).
The compounds and pharmaceutical compositions used in the methods of the present invention can also be delivered in a controlled release system. In one embodiment, a pump may be used (see, Sefton, 1987, CRC Crit. Ref. Biomed. Eng. 14:201; Buchwald et al. Surgery, 1980, 88, 507; Saudek et al. N Engl. J. Med. 1989, 321, (574). Additionally, a controlled release system can be placed in proximity of the therapeutic target. (See, Goodson, Medical Applications of Controlled Release, 1984, 2, 115-138).
The pharmaceutical compositions used in the methods of the instant invention can also contain the active ingredient in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs. Compositions intended for oral use may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions, and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents and preserving agents in order to provide pharmaceutically elegant and palatable preparations. Tablets contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients which are suitable for the manufacture of tablets. These excipients may be, for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, such as microcrystalline cellulose, sodium crosscarmellose, corn starch, or alginic acid; binding agents, for example starch, gelatin, polyvinyl-pyrrolidone or acacia, and lubricating agents, for example, magnesium stearate, stearic acid or talc. The tablets may be un-coated or coated by known techniques to mask the taste of the drug or delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a water soluble taste masking material such as hydroxypropylmethyl-cellulose or hydroxypropylcellulose, or a time delay material such as ethyl cellulose, or cellulose acetate butyrate may be employed as appropriate.
Formulations for oral use may also be presented as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water soluble carrier such as polyethyleneglycol or an oil medium, for example peanut oil, liquid paraffin, or olive oil.
Aqueous suspensions contain the active material in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethyl-cellulose, sodium alginate, polyvinyl-pyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally-occurring phosphatide, for example lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example heptadecaethylene-oxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more preservatives, for example ethyl, or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose, saccharin or aspartame.
Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil, for example arachisd oil, olive oil, sesame oil or coconut oil, or in mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an anti-oxidant such as butylated hydroxyanisol or alpha-tocopherol.
Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring and coloring agents, may also be present. These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid.
The compounds and pharmaceutical compositions used in the methods of the instant invention may also be in the form of an oil-in-water emulsions. The oily phase may be a vegetable oil, for example olive oil or arachis oil, or a mineral oil, for example liquid paraffin or mixtures of these. Suitable emulsifying agents may be naturally-occurring phosphatides, for example soy bean lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example sorbitan monooleate, and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening agents, flavoring agents, preservatives and antioxidants.
Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative, flavoring and coloring agents and antioxidant.
The pharmaceutical compositions may be in the form of a sterile injectable aqueous solution. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution.
The sterile injectable preparation may also be a sterile injectable oil-in-water microemulsion where the active ingredient is dissolved in the oily phase. For example, the active ingredient may be first dissolved in a mixture of soybean oil and lecithin. The oil solution then introduced into a water and glycerol mixture and processed to form a microemulsion.
The injectable solutions or microemulsions may be introduced into a patient's blood-stream by local bolus injection. Alternatively, it may be advantageous to administer the solution or microemulsion in such a way as to maintain a constant circulating concentration of the instant compound. In order to maintain such a constant concentration, a continuous intravenous delivery device may be utilized. An example of such a device is the Deltec CADD-PLUS™ model 5400 intravenous pump.
The pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleagenous suspension for intramuscular and subcutaneous administration. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example as a solution in 1,3-butane diol. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation ofinjectables.
The compounds of the present invention used in the methods of the present invention may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the inhibitors with a suitable non-irritating excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter, glycerinated gelatin, hydrogenated vegetable oils, mixtures of polyethylene glycols of various molecular weights and fatty acid esters of polyethylene glycol.
For topical use, creams, ointments, jellies, solutions or suspensions, etc., containing a compound or composition of the invention can be used. As used herein, topical application can include mouth washes and gargles.
The compounds used in the methods of the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles and delivery devices, or via transdermal routes, using those forms of transdermal skin patches well known to those of ordinary skill in the art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.
The methods, compounds and compositions of the instant invention may also be used in conjunction with other well known therapeutic agents that are selected for their particular usefulness against the condition that is being treated. For example, the instant compounds may be useful in combination with known anti-cancer and cytotoxic agents. Further, the instant methods and compounds may also be useful in combination with other inhibitors of parts of the signaling pathway that links cell surface growth factor receptors to nuclear signals initiating cellular proliferation.
The methods of the present invention may also be useful with other agents that inhibit angiogenesis and thereby inhibit the growth and invasiveness of tumor cells, including, but not limited to VEGF receptor inhibitors, including ribozymes and antisense targeted to VEGF receptors, angiostatin and endostatin.
Examples of antineoplastic agents that can be used in combination with the compounds and methods of the present invention include, in general, and as appropriate, alkylating agents, anti-metabolites, epidophyllotoxins, antineoplastic enzymes, topoisomerase inhibitors, procarbazines, mitoxantrones, platinum coordination complexes, biological response modifiers and growth inhibitors, hormonal/anti-hormonal therapeutic agents and haematopoietic growth factors. Exemplary classes of antineoplastic include the anthracyclines, vinca drugs, mitomycins, bleomycins, cytotoxic nucleosides, epothilones, discodermolides, pteridines, diynenes and podophyllotoxins. Particularly useful members of those classes include, for example, carminomycin, daunorubicin, aminopterin, methotrexate, methopterin, dichloromethotrexate, mitomycin C, porfiromycin, 5-fluorouracil, 6-mercaptopurine, gemcitabine, cytosine arabinoside, podophyllotoxin or podo-phyllotoxin derivatives such as etoposide, etoposide phosphate or teniposide, melphalan, vinblastine, vincristine, leurosidine, vindesine, leurosine, paclitaxel and the like. Other useful antineoplastic agents include estramustine, carboplatin, cyclophosphamide, bleomycin, gemcitibine, ifosamide, melphalan, hexamethyl melamine, thiotepa, cytarabin, idatrexate, trimetrexate, dacarbazine, L-asparaginase, camptothecin, CPT-11, topotecan, ara-C, bicalutamide, flutamide, leuprolide, pyridobenzoindole derivatives, interferons and interleukins.
When a compound or composition of the invention is administered into a human subject, the daily dosage will normally be determined by the prescribing physician with the dosage generally varying according to the age, weight, and response of the individual patient, as well as the severity of the patient's symptoms.
In one exemplary application, a suitable amount of compound is administered to a mammal undergoing treatment for cancer, for example, breast cancer. Administration typically occurs in an amount of between about 0.01 mg/kg of body weight to about 100 mg/kg of body weight per day (administered in single or divided doses), more preferably at least about 0.1 mg/kg of body weight per day. A particular therapeutic dosage can include, e.g., from about 0.01 mg to about 1000 mg of compound, and preferably includes, e.g., from about 1 mg to about 1000 mg. The quantity of active compound in a unit dose of preparation may be varied or adjusted from about 0.1 mg to 1000 mg, preferably from about 1 mg to 300 mg, more preferably 10 mg to 200 mg, according to the particular application. The amount administered will vary depending on the particular IC50 value of the compound used and the judgment of the attending clinician taking into consideration factors such as health, weight, and age. In combinational applications in which the compound is not the sole active ingredient, it may be possible to administer lesser amounts of compound and still have therapeutic or prophylactic effect.
Preferably, the pharmaceutical preparation is in unit dosage form. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component, e.g., an effective amount to achieve the desired purpose.
The actual dosage employed may be varied depending upon the requirements of the patient and the severity of the condition being treated. Determination of the proper dosage for a particular situation is within the skill of the art. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small amounts until the optimum effect under the circumstances is reached. For convenience, the total daily dosage may be divided and administered in portions during the day if desired.
The amount and frequency of administration of the compounds and compositions of the present invention used in the methods of the present invention, and if applicable other chemotherapeutic agents and/or radiation therapy, will be regulated according to the judgment of the attending clinician (physician) considering such factors as age, condition and size of the patient as well as severity of the disease being treated.
The chemotherapeutic agent and/or radiation therapy can be administered according to therapeutic protocols well known in the art. It will be apparent to those skilled in the art that the administration of the chemotherapeutic agent and/or radiation therapy can be varied depending on the disease being treated and the known effects of the chemotherapeutic agent and/or radiation therapy on that disease. Also, in accordance with the knowledge of the skilled clinician, the therapeutic protocols (e.g., dosage amounts and times of administration) can be varied in view of the observed effects of the administered therapeutic agents (i.e., antineoplastic agent or radiation) on the patient, and in view of the observed responses of the disease to the administered therapeutic agents.
Also, in general, the compounds of the invention need not be administered in the same pharmaceutical composition as a chemotherapeutic agent, and may, because of different physical and chemical characteristics, be administered by a different route. For example, the compounds/compositions may be administered orally to generate and maintain good blood levels thereof, while the chemotherapeutic agent may be administered intravenously. The determination of the mode of administration and the advisability of administration, where possible, in the same pharmaceutical composition, is well within the knowledge of the skilled clinician. The initial administration can be made according to established protocols known in the art, and then, based upon the observed effects, the dosage, modes of administration and times of administration can be modified by the skilled clinician.
The particular choice of compound (and where appropriate, chemotherapeutic agent and/or radiation) will depend upon the diagnosis of the attending physicians and their judgment of the condition of the patient and the appropriate treatment protocol.
The compounds/compositions of the invention (and where appropriate chemotherapeutic agent and/or radiation) may be administered concurrently (e.g., simultaneously, essentially simultaneously or within the same treatment protocol) or sequentially, depending upon the nature of the proliferative disease, the condition of the patient, and the actual choice of chemotherapeutic agent and/or radiation to be administered in conjunction (i.e., within a single treatment protocol) with the compound/composition.
In combinational applications and uses, the compound/composition and the chemotherapeutic agent and/or radiation need not be administered simultaneously or essentially simultaneously, and the initial order of administration of the compound/composition, and the chemotherapeutic agent and/or radiation, may not be important. Thus, the compounds/compositions of the invention may be administered first followed by the administration of the chemotherapeutic agent and/or radiation; or the chemotherapeutic agent and/or radiation may be administered first followed by the administration of the compounds/compositions of the invention. This alternate administration may be repeated during a single treatment protocol. The determination of the order of administration, and the number of repetitions of administration of each therapeutic agent during a treatment protocol, is well within the knowledge of the skilled physician after evaluation of the disease being treated and the condition of the patient. For example, the chemotherapeutic agent and/or radiation may be administered first, especially if it is a cytotoxic agent, and then the treatment continued with the administration of the compounds/compositions of the invention followed, where determined advantageous, by the administration of the chemotherapeutic agent and/or radiation, and so on until the treatment protocol is complete.
Thus, in accordance with experience and knowledge, the practicing physician can modify each protocol for the administration of a compound/composition for treatment according to the individual patient's needs, as the treatment proceeds.
The attending clinician, in judging whether treatment is effective at the dosage administered, will consider the general well-being of the patient as well as more definite signs such as relief of disease-related symptoms, inhibition of tumor growth, actual shrinkage of the tumor, or inhibition of metastasis. Size of the tumor can be measured by standard methods such as radiological studies, e.g., CAT or MRI scan, and successive measurements can be used to judge whether or not growth of the tumor has been retarded or even reversed. Relief of disease-related symptoms such as pain, and improvement in overall condition can also be used to help judge effectiveness of treatment.
V. ASSAYS FOR DETERMINING HSP90 BINDING AND DOWNSTREAM EFFECT
A variety of in vitro and in vivo assays are available to test the effect of the compounds of the invention on HSP90. HSP90 competitive binding assays and functional assays can be performed as known in the art substituting in the compounds of the invention. Chiosis et al. Chemistry & Biology 2001, 8, 289-299, describe some of the known ways in which this can be done. For example, competition binding assays using, e.g., geldanamycin or 17-AAG as a competitive binding inhibitor of HSP90 can be used to determine relative HSP90 affinity of the compounds of the invention by immobilizing the compound of interest or other competitive inhibitor on a gel or solid matrix, preincubating HSP90 with the other inhibitor, passing the preincubated mix over the gel or matrix, and then measuring the amount of HSP90 that retains or does not retain on the gel or matrix.
Downstream effects can also be evaluated based on the known effect of HSP90 inhibition on function and stability of various steroid receptors and signaling proteins including, e.g., Raf1 and HER2. Compounds of the present invention induce dose-dependent degradation of these molecules, which can be measured using standard techniques. Inhibition of HSP90 also results in up-regulation of HSP90 and related chaperone proteins that can similarly be measured. Antiproliferative activity on various cancer cell lines can also be measured, as can morphological and functional differentiation related to HSP90 inhibition.
Many different types of methods are known in the art for determining protein concentrations and measuring or predicting the level of proteins within cells and in fluid samples. Indirect techniques include nucleic acid hybridization and amplification using, e.g., polymerase chain reaction (PCR). These techniques are known to the person of skill and are discussed, e.g., in Sambrook, Fritsch & Maniatis Molecular Cloning: A Laboratory Manual, 2nd ed., Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y., 1989; Ausubel, et al. Current Protocols in Molecular Biology, John Wiley & Sons, NY, 1994, and, as specifically applied to the quantification, detection, and relative activity of HER2/Neu in patient samples, e.g., in U.S. Patents 4,699,877 , 4,918,162 , 4,968,603 , and 5,846,749 . A brief discussion of two generic techniques that can be used follows.
The determination of whether cells overexpress or contain elevated levels of HER2 can be determined using well known antibody techniques such as immunoblotting, radioimmunoassays, western blotting, immunoprecipitation, enzyme-linked immunosorbant assays (ELISA), and derivative techniques that make use of antibodies directed against HER2. As an example, HER2 expression in breast cancer cells can be determined with the use of an immunohistochemical assay, such as the Dako Hercep™ test (Dako Corp., Carpinteria, CA). The Hercep™ test is an antibody staining assay designed to detect HER2 overexpression in tumor tissue specimens. This particular assay grades HER2 expression into four levels: 0, 1, 2, and 3, with level 3 representing the highest level of HER2 expression. Accurate quantitation can be enhanced by employing an Automated Cellular Imaging System (ACIS) as described, e.g., by Press, M. et al. Modern Pathology 2000, 13, 225A.
Antibodies, polyclonal or monoclonal, can be purchased from a variety of commercial suppliers, or may be manufactured using well-known methods, e.g., as described in Harlow et al. Antibodies: A Laboratory Manual, 2nd ed; Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y., 1988.
HER2 overexpression can also be determined at the nucleic acid level since there is a reported high correlation between overexpression of the HER2 protein and amplification of the gene that codes for it. One way to test this is by using RT-PCR. The genomic and cDNA sequences for HER2 are known. Specific DNA primers can be generated using standard, well-known techniques, and can then be used to amplify template already present in the cell. An example of this is described in Kurokawa, H. et al. Cancer Res. 2000, 60, 5887-5894. PCR can be standardized such that quantitative differences are observed as between normal and abnormal cells, e.g., cancerous and noncancerous cells. Well known methods employing, e.g., densitometry, can be used to quantitate and/or compare nucleic acid levels amplified using PCR.
Similarly, fluorescent in situ hybridization (FISH) assays and other assays can be used, e.g., Northern and/or Southern blotting. These rely on nucleic acid hybridization between the HER2 gene or mRNA and a corresponding nucleic acid probe that can be designed in the same or a similar way as for PCR primers, above. See, e.g., Mitchell MS, and Press M.F. Onco/., Suppl. 1999, 12, 108-116. For FISH, this nucleic acid probe can be conjugated to a fluorescent molecule, e.g., fluorescein and/or rhodamine, that preferably does not interfere with hybridization, and which fluorescence can later be measured following hybridization. See, e.g., Kurokawa, H et al, Cancer Res. 2000, 60, 5887-5894 (describing a specific nucleic acid probe having sequence 5'-FAM-NucleicAcid-TAMRA-p-3' sequence). ACIS-based approaches as described above can be employed to make the assay more quantitative (de la Torre-Bueno, J., et al. Modern Pathology 2000, 13, 221A).
Immuno and nucleic acid detection can also be directed against proteins other than HSP90 and HER2, which proteins are nevertheless affected in response to HSP90 inhibition.
The following examples are offered by way of illustration only and are not intended to be limiting of the full scope and spirit of the invention.

The chemical reagents used to create the novel products of the invention below are all available commercially, e.g., from Aldrich Chemical Co., Milwaukee, WI, USA. Otherwise their preparation is facile and known to one of ordinary skill in the art, or it is referenced or described herein.
The final compounds were usually purified by preparative TLC (silica gel 60 Å, Whatman Partisil PK6F) or flash chromatography (silica gel 60 Å, EMD Chemicals) using EtOAc/hexane or MeOH/CH2Cl2 as eluents. Rf's were measured using silica gel TLC plates (silica gel 60 Å, EMD Chemicals). Analytical HPLC chromatograms were obtained using a C18 column (Agilent Zorbax 300SB-C18; 5 microns; 4.6 mm x 150 mm). A gradient was applied between solvent A (0.1% TFA in H2O) and solvent B (0.5% TFA in CH3CN) increasing the proportion of A linearly from 5% (t=0) to 100% (t=7.00 min), with a constant flow rate of 1 mL/min. The samples were diluted to typically 0.1-1 mg/mL in MeOH or CH3CN and the injection volumes were typically 10 µL. The column was not heated, and UV detection was effected at 254 nm. 1H-NMR spectra were recorded on a Bruker Avance 400 MHz spectrometer.
The chemical names were generated using the Beilstein Autonom 2.1 software.

BIOLOGY EXAMPLES Example A. rHSP90 Competitive Binding Assay
Five microgram of purified rHSP90 protein (Stressgen, BC, Canada, #SPP-770) in phosphated buffered saline (PBS) was coated on 96 well plates by incubating overnight at 4°C. Unbound protein was removed and the coated wells were washed twice with 200 µL PBS. DMSO controls (considered as untreated samples) or test compounds were then added at 100-30-10-3-1-0.3 µM dilutions (in PBS), the plates mixed for 30 seconds on the plate shaker, and then incubated for 60 min. at 37 °C. The wells were washed twice with 200 µL PBS, and 10 µM biotinylated-geldanamycin (biotin-GM) was added and incubated for 60 min. at 37 °C. The wells were washed again twice with 200 µL PBS, before the addition of 20 µg/mL streptavidin-phycoerythrin (streptavidin-PE) (Molecular Probes, Eugene, OR) and incubation for 60 min. at 37°C. The wells were washed again twice with 200 µL PBS. Relative fluorescence units (RFU) was measured using a SpectraMax Gemini XS Spectrofluorometer (Molecular Devices, Sunnyvale, CA) with an excitation at 485 nm and emission at 580 nm; data was acquired using SOFTmaX®PRO software (Molecular Devices Corporation, Sunnyvale, CA). The background was defined as the RFU generated from wells that were not coated with HSP90 but were treated with the biotin-GM and streptavidin-PE. The background measurements were substrated from each sample treated with biotin-GM and streptavidin-PE measurements before other computation. Percent inhibition of binding for each sample was calculated from the background subtracted values as follows: % binding inhibition = RFU untreated - RFU treated / RFU untreated ] × 100.
Example B. Cell Lysate Binding Assay
MCF7 breast carcinoma cell lysates were prepared by douncing in lysing buffer (20 mM HEPES, pH 7.3, 1 mM EDTA, 5 mM MgCl2, 100 mM KCl), and then incubated with or without test compound for 30 mins at 4 °C, followed by incubation with biotin-GM linked to BioMag™ streptavidin magnetic beads (Qiagen) for 1 hr at 4 °C. The tubes were placed on a magnetic rack, and the unbound supernatant removed. The magnetic beads were washed three times in lysis buffer and boiled for 5 mins at 95 °C in SDS-PAGE sample buffer. Samples were analyzed on SDS protein gels, and Western blots done for rHSP90. Bands in the Western Blots were quantitated using the Bio-rad Fluor-S MultiImager, and the % inhibition of binding of rHSP90 to the biotin-GM was calculated.
The lysate binding ability of selected compounds of the invention based on the above assay is summarized in Table 5. The IC50 reported is the concentration of test compound needed to achieve 50% inhibition of the biotin-GM binding to rHSP90 in the MCF7 cell lysates.

Phycoerythrin (PE) conjugated anti HER2/Neu antibody (Becton Dickinson, #340552), or PE conjugated anti-keyhole limpet hemacyanin [KLH] (Becton Dickinson, #340761) control antibody was added at a dilution of 1:20 and 1:40 respectively (final concentration was 1 µg/mL) and the cells were pipeted up and down to form a single cell suspension, and incubated for 15 mins. The cells were washed twice with 200 µL, BA buffer, and resuspended in 200 µL BA buffer, and transferred to FACSCAN tubes with an additional 250 µL BA buffer. Samples were analyzed using a FACSCalibur™ flow cytometer (Becton Dickinson, San Jose, CA) equipped with Argon-ion laser that emits 15 mW of 488 nm light for excitation of the PE fluorochrome. 10,000 events were collected per sample. A fluorescence histogram was generated and the mean fluorescence intensity (MFI) of each sample was determined using Cellquest software. The background was defined as the MFI generated from cells incubated with control IgG-PE, and was subtracted from each sample stained with the HER2/Neu antibody. Cells incubated with DMSO was always done as untreated controls since the compounds were resuspended in DMSO. Percent degradation of HER2 was calculated as follows: % HER 2 degraded = MFl untreated cells - MFl treated cells / MFl untreated cell × 100
The HER2 degradation ability of selected compounds of the invention based on this assay is summarized in Table 5. IC50 is defined as the concentration at which there was 50% degradation of the HER2/Neu protein.
Example D: MTS Assay
MTS assays measures the cytotoxicity of geldanamycin derivatives. MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium is a tetrazolium dye that is converted to a formazan product by dehydrogenase enzymes of metabolically active cells (Corey, A. et al. "Use of an aqueous soluble tetrazolium/formazan assay for cell growth assays in culture," Cancer Commun. 1991, 3, 207-212). Cells were seeded in 96 well plates at 2000 cells/well and allowed to adhere overnight in Dulbecco's modified Eagle's medium supplemented with 10% fetal bovine serum. The final culture volume was 100 µl. Viable cell number was determined by using the Celltiter 96 AQueousNon-radioactive Cell Proliferation Assay (Promega, Madison WI). The MTS /PMS (phenazine methosulfate) solution was mixed at a ratio of 20:1, and 20 µL was added per well to 100 µL of culture medium. After 2-4 hours, the formation of the formazan product was measured at 490 nm absorbance using a multiwell plate spectrophotometer. Background was determined by measuring the Abs 490 nm of cell culture medium and MTS-PMS in the absence of cells and was subtracted from all values. Percent viable cells was calculated as follows: % viable cells = Abs at 490 nm treated cells / Abs at 490 nm untreated cells × 100
The effect of selected compounds of the invention on MCF7 breast carcinoma cells according to the MTS assay is summarized in Table 5. IC50 was defined as the concentration of the compound which gave rise to 50% viable cell number.

The chemical reagents used to create the novel products of the invention below are all available commercially, e.g., from Aldrich Chemical Co., Milwaukee, WI, USA. Otherwise their preparation is facile and known to one of ordinary skill in the art, or it is referenced or described herein.
The final compounds were usually purified by preparative TLC (silica gel 60 A, Whatman Partisil PK6F) or flash chromatography (silica gel 60 Å, EMD Chemicals) using EtOAc/hexane or MeOH/CH2Cl2 as eluents. Rf's were measured using silica gel TLC plates (silica gel 60 Å, EMD Chemicals). Analytical HPLC chromatograms were obtained using a C18 column (Agilent Zorbax 300SB-C18; 5 microns; 4.6 mm x 150 mm). A gradient was applied between solvent A (0.1% TFA in H2O) and solvent B (0.5% TFA in CH3CN) increasing the proportion of A linearly from 5% (t=0) to 100% (t=7.00 min), with a constant flow rate of 1 mL/min. The samples were diluted to typically 0.1-1 mg/mL in MeOH or CH3CN and the injection volumes were typically 10 µL. The column was not heated, and UV detection was effected at 254 nm. 1H-NMR spectra were recorded on a Bruker Avance 400 MHz spectrometer.
The chemical names were generated using the Beilstein Autonom 2.1 software.

III. PREPARATION OF PYRAZOLOPYRIMIDINES (FORMULA III) A. Materials and Methods
The chemical reagents used to create the novel products of the invention below are all available commercially, e.g., from Aldrich Chemical Co., Milwaukee, WI, USA. Otherwise their preparation is facile and known to one of ordinary skill in the art, or it is referenced or described herein.
The final compounds were usually purified by preparative TLC (silica gel 60 A, Whatman Partisil PK6F) or flash chromatography (silica gel 60 A, EMD Chemicals) using EtOAc/hexane or MeOH/CH2Cl2 as eluents. Rfs were measured using silica gel TLC plates (silica gel 60 A, EMD Chemicals). Analytical HPLC chromatograms were obtained using a C18 column (Agilent Zorbax 300SB-C18; 5 microns; 4.6 mm x 150 mm). A gradient was applied between solvent A (0.1 % TFA in H2O) and solvent B (0.5% TFA in CH3CN) increasing the proportion of A linearly from 5% (t=0) to 100% (t=7.00 min), with a constant flow rate of 1 mL/min. The samples were diluted to typically 0.1-1 mg/mL in MeOH or CH3CN and the injection volumes were typically 10 µL. The column was not heated, and UV detection was effected at 254 nm. 1H-NMR spectra were recorded on a Bruker Avance 400 MHz spectrometer.
The chemical names were generated using the Beilstein Autonom 2.1 software.

BIOLOGY EXAMPLES
The biological activites of selected pyrazolopyrimidines were determined using four assays: the inhibition of binding of biotinylated geldamamycin (biotin-GM) to rHSP90, the lysate binding ability, the HER2 degradation ability and the cytotoxity measurement. These assays have been described in Examples A, B, C and D in the previous sections. The biological activites are summarized in Table 7.
IV. PREPARATION OF TRIAZOLOPYRIMIDINES OF FORMULA IV A. Materials and Methods
The chemical reagents used to create the novel products of the invention below are all available commercially, e.g., from Aldrich Chemical Co., Milwaukee, WI, USA. Otherwise their preparation is facile and known to one of ordinary skill in the art, or it is referenced or described herein.
The final compounds were usually purified by preparative TLC (silica gel 60 Å, Whatman Partisil PK6F) or flash chromatography (silica gel 60 Å, EMD Chemicals) using EtOAc/hexane or MeOH/CH2Cl2 as eluents. Rfs were measured using silica gel TLC plates (silica gel 60 Å, EMD Chemicals). Analytical HPLC chromatograms were obtained using a C18 column (Agilent Zorbax 300SB-C18; 5 microns; 4.6 mm x 150 mm). A gradient was applied between solvent A (0.1 % TFA in H2O) and solvent B (0.5% TFA in CH3CN) increasing the proportion of A linearly from 5% (t=0) to 100% (t=7.00 min), with a constant flow rate of 1 mL/min. The samples were diluted to typically 0.1-1 mg/mL in MeOH or CH3CN and the injection volumes were typically µL. The column was not heated, and UV detection was effected at 254 nm. 1H-NMR spectra were recorded on a Bruker Avance 400 MHz spectrometer.
The chemical names were generated using the Beilstein Autonom 2.1 software.
