Description

Use of 4-amino-quinazolines as anti cancer agents

FIELD OF THE INVENTION

The present invention provides compositions and methods for modulating the activity of PKB. In particular, this invention relates to 4-amino- quinazolines and there salts or solvates, that specifically bind with the human PKB protein. Such compounds have been shown to inhibit the activity of PKB.

BACKGROUND OF THE INVENTION

One of the principal mechanisms by which cellular regulation is effected is through the transduction of extracellular signals across the membrane that in turn modulate biochemical pathways within the cell. Protein phosphorylation represents one course by which intracellular signals are propagated from molecule to molecule resulting finally in a cellular response. These signal transduction cascades are highly regulated and often overlapping as evidenced by the existence of many protein kinases as well as phosphatases. Phosphorylation of proteins occurs predominantly at serine, threonine, or tyrosine residues and protein kinases have therefore been classified by their specificity of phosphorylation site i.e. serine/threonine kinases and tyrosine kinases. Because phosphorylation is such a ubiquitous process within cells and because cellular phenotypes are largely influenced by the activity of these pathways, it is currently believed that a number of disease states and/or disorders are a result of either aberrant activation or functional mutations in the molecular components of kinase cascades. Consequently, considerable attention has been devoted to the characterization of these proteins and compounds that are able to modulate there activity ( for a review see: Weinstein-Oppenheimer et al. Pharma. &. Therap., 2000, 88, 229-279). The protein kinase PKB (also known as AKT and RAC-PK ) is a member of the AKT/PKB family of serine/threonine kinases and has been shown to be involved in a diverse set of signaling pathways in human malignancy (Nicholson et al., Cell. Signal., 2002, 14, 381-395. PKB, like other members of the AKT/PKB family is located in the cytosol of unstimulated cells and translocates to the cell membrane following stimulation. PKB translocation can be activated by several ligands including platelet derived growth factor, epidermal growth factor, basic fibroblast growth factor, cellular stress such as heat shock and hyperosmolarity as well as insulin (Bos, Trends Biochem. Sci., 1995, 20, 441-442) and other studies have shown that this activation is through PI3 kinase which is wortmannin sensitive (Franke et al., Science, 1997, 275, 665-668). Once localized to the plasma membrane, PKB has been shown to mediate several functions within the cell including apoptosis, the metabolic effects of insulin, induction of differentiation and/or proliferation, protein synthesis and stress responses (Alessi and Cohen, Curr. Opin. Genet. Dev., 1998, 8, 55-62; Downward, Curr. Opin. Cell Biol., 1998, 10, 262-267).

PKB was cloned independently in 1991 by three groups (Bellacosa et al., Science, 1991 , 254, 274-277; Coffer and Woodgett, Eur. J. Biochem., 1991 , 201 , 475-481 ; Jones et al., Cell Regul., 1991 , 2, 1001- 1009) but its association with primary human gastric carcinoma was recognized as early as 1987 (Staal et al., Proc. Natl. Acad. Sci. U S A, 1987, 84, 5034-5037). Sequencing of PKBα revealed homology within the kinase domains to the PKA (-68%) and PKC isozymes (-73%) (Jones et al., Proc. Natl. Acad. Sci. U.S.A., 1991 , 88, 4171-5) a fact that lent to its renaming as PKB. There are three cellular isoforms of PKB and two splice variants (PKBα, β, γ, βi, yύ Brazil, et al. Trends in Bio Sci, 2001 , 26, 657-663). PKBα was found to be amplified or overexpressed in gastric adenocarcinomas and in a breast cancer cell line (Staal et al., Proc. Natl. Acad. Sci. U.S.A., 1887, 84, 5034-7. ;Jones et al., Cell Regul., 1991 , 2, 1001-9). PKBβ is amplified or overexpressed in 3% of breast (Bellacosa etal., Int. J. Cancer, 1995 64, 280-5), 12% of pancreatic (Cheng et al., Proc. Natl. Acad. Sci.

U.S.A., 1996, 93, 3636-41 ), and 15% of ovarian cancers (Bellacosa et al.,

Int. J. Cancer, 1995, 64, 280-5; Cheng et al., Proc. Natl. Acad. Sci. U.S.A.,

1992, 89, 9267-71).

PKB7 is overexpressed in estrogen receptor-deficient breast cancer and in androgen-independent prostate cell lines (Nakatani et al., J. Biol. Chem.

1999, 274, 21528-32).

PKB has been proposed to be a gene involved in chromosomal rearrangement at chromosome band 14q32. This locus is known to undergo rearrangement in human T-cell malignancies such as prolymphocytic leukemias, and mixed lineage childhood leukemias (Staal et al., Genomics, 1988, 2, 96-98).

PKB also plays a role in the prevention of "programmed cell death" or apoptosis by inhibitory phoshorylation of ASK-1 , Bad, Caspase9 and FKHR (for review see Nickolson et al., Cell Signaling 2001 , 14, 281-395). It has been demonstrated that PKB provides a survival signal (for review see Lawlor et al., J. of Cell Science 2001 , 114, 2903-2910) to cells protecting them from a number of agents including UV radiation (Dudek et al., Science, 1997, 275, 661-665), withdrawal of IGF1 from neuronal cells, detachment from the extracellular matrix, stress and heat shock (Alessi and Cohen, Curr. Opin. Genet. Dev., 1998, 8, 55-62).

The dual specific phosphatase PTEN ( phosphatase and tensin homologue deleted on chromosome ten) increases the Ptdlns(3, 4, 5)P₃ level in the cell by dephosphorylation of Ptdlns(3, 4, 5)P₃. Ptdlns(3, 4, 5)P₃ binds to the PH domain ( Pleckstrin homology domain) of PKB. This binding is an essential step for membrane translocation and activation of PKB. PTEN is a tumor suppressor gene mutated in a large fraction of glioblastoma and melanoma cell lines, advances prostate cancers and endometrial cancers.

Furthermore it is deleted in >80 % of patients with inherited conditions such as Cowden disease, Lhermitte-Duclose disease and Bannayan Zonana Syndrome. The patients display several similar features, including multiple benign tumors (harmatomas), and an increased susceptibility to breast and thyroid malignancies (Di Cristofano et al. Cell, 2000, 100, 387-390).

Cell lines derived from mice heterocygous for PTEN^{+ "} (heterocygous PTEN^"'^" mice are not viable) show increased Ptdlns(3, 4, 5)P₃ levels paralleled by increased PKB activity, with a concomitant decreased sensitivity to apoptosis (Di Christofano et al. Nat. Genet. 1998, 19, 348- 355; Stambolic et al., Cell, 1998, 95, 29-39, Myers et al., Proc. Natl. Acad. Si. U.S.A., 1998, 96 13513-13518).

PKB is also able to promote cell cycle progression by inhibiting p21 cell cycle inhibitor (Zhou et al.; Nat. Cell Biol., 2002,3, 245-252).

The identification of signal transduction pathway and the detection of cross talks can be performed by methods known in the art, for example cell line or transgenic animal models, for example according methods described therein.

The susceptibility of a particular cell to treatment with the subject compounds may be determined by in vitro testing. Typically a culture of the cell is combined with a subject compound at varying concentrations for a period of time sufficient to allow the active agents to induce cell death or inhibit migration, usually between about one hour and one week. For in vitro testing, cultured cells from a biopsy sample may be used. The viable cells left after treatment are then counted. Another test cell line would be a PTEN deficient cell line that shows enhanced PKB activity, concomitant by increase resistance to apoptotic inducers as e.g. cisplatin. A treatment with the subject compound would be overcome this apoptose resistance.

For the identification of a signal transduction pathway and the detection of cross talks with other signaling pathways, cell culture ( e.g. Khwaja et al., EMBO, 1997, 16, 2783-93) models or transgenic animal models (White et al., Oncogene, 2001 , 20, 7064-7072) were generated by various scientists. For the examintion of particular steps in the signal transduction cascade, interfering compounds ( Stephens et al., Biochemical J., 2000, 351 , 95- 105) were used for signal modulation.

For the identification of kinase inhibitors various assay systems are available. In scintillation proximity assay ( Sorg et al., J. of. Biomolecular Screening, 2002, 7, 11-19) and flashplate assay the radioactive phosphorylation of a protein or peptide as substrate with γATP will be measured. In the presents of an inhibitory compound no or decreased radioactive signal is detectable. Furthermore homogeneous time-resolved fluorescence resonance energy transfer (HTR-FRET), and fluorescence polarization (FP) technologies are useful for assay methods (Sills et al., J. of Biomolecular Screening, 2002, 191-214).

Other non-radioactive ELISA based assay methods use specific phospho- antibodies (AB). The phospho-AB binds only the phosphorylated substrate. These binding is detectable with a second peroxidase conjugated anti sheep antibody by chemiluminescence (eet al., 2002, Biochem. J., immediate publication, manuscript BJ20020786).

These findings may explain the overexpression of PKB seen in cancer cells which allows preferential survival and proliferation of the carcinoma by avoiding the normal progression to apoptosis.

Currently, there are no known therapeutic agents which effectively inhibit the activity of PKB. Consequently, there remains a long felt need for additional agents capable of effectively inhibiting PKB function for the activation of pro apoptotic proteins in all kind of cancers as a chemotherapeutic agents.

DETAILED DESCRIPTION

The compounds of the formula I and also the starting substances for their preparation are otherwise prepared by methods known per se, such as are described in the literature (e.g. in the standard works such as Houben-

Weyl, Methoden der organischen Chemie [Methods of Organic Chemistry], Georg-Thieme-Verlag, Stuttgart), namely under reaction conditions which are known and suitable for the reactions mentioned. In this case, use can also be made of variants which are known per se, but not mentioned here in greater detail.

The starting substances, if desired, can also be formed in situ such that they are not isolated from the reaction mixture, but immediately reacted further to give the compounds of the formula I.

The compounds of the formula I can be obtained by liberating them from their functional derivatives by solvolysis, in particular hydrolysis or by hydrogenolysis. Preferred starting substances for the solvolysis or hydrogenolysis are those which otherwise correspond to the formula I, but instead of one or more free amino and/or hydroxyl groups contain corresponding protected amino and/or hydroxyl groups, in particular those which instead of an H-N- group carry an R'-N- group, in which R' is an amino protective group and/or those which instead of the H atom of a hydroxyl group carry a hydroxyl protective group, e.g. those which correspond to the formula I, but instead of a group -COOH carry a group -COOR", in which R" is a hydroxyl protective group.

A number of - identical or different - protected amino and/or hydroxyl groups can also be present in the molecule of the starting substance. If the protective groups present are different from one another, in many cases they can be removed selectively (lit.: T.W. Greene, P.G.M. Wuts, Protective Groups in Organic Chemistry, 2nd ed., Wiley, New York 1991 or P.J.

Kocienski, Protecting Groups, 1 st ed., Georg Thieme Verlag, Stuttgart - New-York, 1994).

The expression "amino protective group" is generally known and relates to groups which are suitable for protecting (for blocking) an amino group against chemical reactions, but which are easily removable after the desired chemical reaction has been carried out at other positions in the molecule. Typical groups of this type are, in particular, unsubstituted or substituted acyl, aryl, aralkoxymethyl or aralkyl groups. Since the amino protective groups are removed after the desired reaction (or reaction sequence), their nature and size is otherwise not critical; however, those having 1-20, in particular 1-8, C atoms are preferred. The expression "acyl group" is to be interpreted in the widest sense in connection with the present process. It includes acyl groups derived from aliphatic, araliphatic, aromatic or heterocyclic carboxylic acids or sulfonic acids and, in particular, alkoxycarbonyl groups, aryloxycarbonyl groups and especially aralkoxycarbonyl groups. Examples of acyl groups of this type are alkanoyl such as acetyl, propionyl, butyryl; aralkanoyl such as phenylacetyl; aroyl such as benzoyl or toluyl; aryloxyalkanoyl such as POA; alkoxycarbonyl such as methoxycarbonyl, ethoxycarbonyl, 2,2,2-trichloroethoxycarbonyl, BOC, 2-iodoethoxycarbonyl; aralkyloxycarbonyl such as CBZ ("carbobenzoxy"), 4-methoxybenzyloxycarbonyl (MOZ), 4-Nitro- benzyloxycarbonyl oder 9-fluorenylmethoxycarbonyl (Fmoc); 2- (phenylsulfonyl)ethoxycarbonyl; trimethylsilylethoxycarbonyl (Teoc) or arylsulfonyl such as 4-methoxy-2,3,6-trimethylphenyl-sulfonyl (Mtr). Preferred amino protective groups are BOC, furthermore CBZ, Fmoc, benzyl and acetyl; particularly preferred Fmoc.

The expression "hydroxyl protective group" is also generally known and relates to groups which are suitable for protecting a hydroxyl group against chemical reactions, but which are easily removable after the desired chemical reaction has been carried out at other positions in the molecule.

Typical groups of this type are the above mentioned unsubstituted or substituted aryl, aralkyl, aroyl or acyl groups, furthermore also alkylgroups, alkyl-, aryl- or aralkylsilylgroups or 0,0- or 0,S-acetals. The nature and size of the hydroxyl protective groups is not critical, since they are removed again after the desired chemical reaction or reaction sequence; groups having 1-20, in particular 1-10 C atoms, are preferred. Examples of hydroxyl protective groups are, inter alia, benzyl, 4-methoxybenzyl or 2,4- dimethoxybenzyl, aroyl groups such as benzoyl or p-nitrobenzoyl, acyl groups such as acetyl or pivaloyl, p-toluolsulfonyl, alkyl groups such as methyl or tert-butyl, but also allyl, alkylsilyl groups such as trimethylsilyl (TMS), triisopropylsilyl (TIPS), tert-butyldimethylsilyl (TBS) or triethylsilyl, trimethylsilylethyl, aralkylsilyl groups such as tert-butyldiphenylsilyl (TBDPS), cyclic acetals such as isopropylidene-, cyclopentylidene-, cyclohexylidene-, benzylidene-, p-methoxybenzylidene- or o,p- dimethoxybenzylideneacetal, acyclic acetales such as tetrahydropyranyl (Thp), methoxymethyl (MOM), methoxyethoxymethyl (MEM), benzyloxymethyl (BOM) or methylthiomethyl (MTM). Acetyl, benzyl, tert- butyl or TBS being particularly preferred.

The liberation of the compounds of the formula I from their functional derivatives depending on the protective group used is known in the present literature such as T.W. Greene, P.G.M. Wuts, Protective Groups in Organic Chemistry, 2nd ed., Wiley, New York 1991 , P.J. Kocienski, Protecting Groups, 1 st ed., Georg Thieme Verlag, Stuttgart - New- York, 1994. In this case, use can also be made of variants which are known per se, but not mentioned here in greater detail.

The groups BOC and O-tert-butyl can preferably be removed, for example, using TFA in dichloromethane or using approximately 3 to 5N HCl in dioxane at 15-30°C, the Fmoc group using an approximately 5 to 50% solution of dimethylamine, diethylamine or piperidine in DMF at 15-30°C.

Preferred starting substances for the solvolysis or hydrogenolysis includes also those which otherwise correspond to the formula I, but are attached to a solid phase. The liberation of the compounds of the formula I from the solid phase is known in the present literature such as Novabiochem - The Combinatorial Chemistry Catalog, March 99 and cited literature.

The solid phase with a carbonate moiety as terminal functional group can preferably be removed, for example, using TFA (50%) in dichloromethane.

The quinazolines of formula I can also preferably be prepared, using either solution or solid-phase techniques.

The term solid phase indicates a resin for solid-phase chemistry, especially for combinatorial chemistry, i.e. by robot- and computer-assisted syntheses, and subjected to mass screening as indicated in US 5,463,564; M. A. Gallop et al., J. Med. Chem. 1994, 37, 1233-1251 and 1385-1401 and MJ. Sofia, Drug Discovery Today 1996, 1 , 27-34). The polymeric material of the solid phase is generally chosen from the group consisting of cross-linked polystyrene, cross-linked polyacrylamide or other resins, natural polymers or silicagels.

The group of cross-linked polystyrene, cross-linked polyacrylamide or other resins includes e.g. polyacrylamide, polymethacrylamide, polyhydroxyethylmethacrylate, polyamide, polystyrene, (meth)acrylate copolymers, for instance from (methy)acrylic acid, esters of (meth)acrylic acid and/or 2-methylene-succinic acid, but-2-enoic acid or maleic acid, polyurethanes or other copolymers.

Suitable terminal functional groups or linkers on the surface of the resin have to be chosen to attach the compounds to the resin. There exists a variety of commercially available resins, e.g. in Novabiochem - The

Combinatorial Chemistry Catalog, March 99. Examples for suitable resins are carbonate resins with a modified carbonate group as terminal functional group like p-nitrophenylcarbonate resin, halogenated resins like Merrifield resin (chloromethylpolystyrene) or carboxy resins like carboxy polystyrene resin or NovaSyn^® TG Carboxy Resin. p-Nitrophenylcarbonate resin is particularly preferred. These and other types of resins well known in the art can be used in the subject invention.

The quinazolines of formula I, in which Y is a direct bond or (CH )_n, can preferably be prepared by combining and reacting a 2-amino-benzonitrile of formula II with an aldehyde of formula III followed by converting the cyano group to an amide group, reacting the given formula IV with a base, chlorinating the given quinazolin-4-one of formula V and reacting the given formula VI with an amine of formula VII. The conversion of the cyano group to the amide group occurs by conventional means which are known to a skilled artisan. Particularly, the conversion occurs via oxidation within the presence of a base.

The quinazolines of formula I, in which Y is -N(R⁵)-(CH₂)_m-, can be prepared by reacting a 2,4-dichloro-quinazoline of formula VIII with an amine of formula VII and reacting the given formula IX with an amine of formula X.

As a rule, the starting compounds of the formulae II, III, VII, VIII and X are known or commercially available.

The unknown compounds, however, can be prepared by methods known per se.

The 2,4-dichloro-quinazolines of formula II in which R and R¹ have a meaning indicated in claim 1 can be prepared by reacting a substituted anthranilic acid with KOCN/acetic acid in the presence of a base and chlorinating the given 1 H-quinazoline-2,4-dione.

The aldehydes of formula III, as a rule, are also commercially available. Furthermore, syntheses for the preparation of aldehydes of formula III, such as, for example, the oxidation of an alcohol, can be used.

The amines of formula VII or X in which R², R³, NR²R³, R⁵, R⁴ and m have a meaning indicated in claim 1 , as a rule, are also commercially available and can be attached to the suitable resin or to a compound of formula VI, VIII or IX by coupling procedures well known in the art and as described in the ensuing Examples. Furthermore, syntheses for the preparation of amines of formula VII or X, such as, for example, the Gabriel synthesis, can be used.

For the preparation of compounds of the formula I in which R⁴ is unsubstituted or substituted biphenyl, heteroarylsubstituted phenyl or aryl- or heteroaryl-substituted thiophenyl, an appropriate compound of the formula I in which R⁴ is phenyl chloride, phenyl bromide, phenyl iodide, thiophenyl chloride, thiophenyl bromide or thiophenyl iodide can be reacted with the appropriate boronic acid derivatives in a Suzu.ki type coupling reaction. This reaction is expediently carried out under Palladium catalysis with different phosphines as coordination ligands, e.g. Pd(P(Ph)₃)₂,

Pd(ll)CI₂dppf, PdOAc₂ + P(R^*)₃ (R^* = phenyl, cyclohexyl, tert-butyl) etc. in the presence of a base such as potassium carbonate, cesium carbonate, DBU, NaOH, in an inert solvent or solvent mixture, e.g. DMF or 1 ,4-dioxane at temperatures between 0° and 150°, preferably between 60° and 120°. Depending on the conditions used, the reaction time is between a few minutes and a number of days. The boronic acid derivatives can be prepared by conventional methods or are commercially available. The reactions can be carried out in analogy to the methods indicated in Suzuki et al., J. Am. Chem. Soc. 1989, 111 , 314ff., Suzuki et al., Chem. Rev. 1995, 95, 2457ff and G.C. Fu et al. Angew. Chem 1998, 110, 3586.

The Suzuki type coupling reaction can be furthermore used to convert radicals R and R¹ into other radicals R and R¹, for e.g. to convert a halogen substituted quinazolines to a quinazoline substituted by substituted or unsubstituted phenyl.

For the preparation of compounds of the formula I in which R or R¹ is allyl, an appropriate compound of the formula I in which R⁴ is quinazoline chloride, quinazoline bromide or quinazoline iodide can be reacted with allyltributyltin in a Stille type coupling reaction. This reaction is expediently carried out under Palladium catalysis with different phosphines as coordination ligands, e.g. Pd(P(Ph)₃)₂, Pd(ll)CI₂dppf, PdOAc₂ + P(R^*)₃ (R^* = phenyl, cyclohexyl, tert-butyl) etc. in an inert solvent or solvent mixture, e.g. DMF or 1 ,4-dioxane at temperatures between 0° and 150°, preferably between 60° and 120°. Depending on the conditions used, the reaction time is between a few minutes and a number of days. For the preparation of compounds of the formula I in which R or R¹ is CH=CH-COOR⁵ or CH=CH-CON(R⁵)₂, an appropriate compound of the formula I in which R⁴ is quinazoline chloride, quinazoline bromide or quinazoline iodide can be reacted with substituted acrylate in a Heck type coupling reaction. This reaction is expediently carried out under Palladium catalysis with different phosphines as coordination ligands, e.g. Pd(P(Ph)₃)₂, Pd(ll)CI₂dppf, PdOAc₂ + P(R^*)₃ (R^* = phenyl, cyclohexyl, tert- butyl) etc. in the presence of a base such as triethyl amine or a catalyst tetrabutylammonium iodide, in an inert solvent or solvent mixture, e.g. DMF or 1 ,4-dioxane at temperatures between 0° and 150°, preferably between 60° and 120°. Depending on the conditions used, the reaction time is between a few minutes and a number of days.

A base of the formula I can be converted into the associated acid addition salt using an acid, for example by reaction of equivalent amounts of the base and of the acid in an inert solvent such as ethanol and subsequent evaporation. Acids which give physiologically acceptable salts are particularly suitable for this reaction. Thus inorganic acids can be used, e.g. sulfuric acid, nitric acid, hydrohalic acids such as hydrochloric acid or hydrobromic acid, phosphoric acids such as orthophosphoric acid, sulfamic acid, furthermore organic acids, in particular aliphatic, alicyclic, araliphatic, aromatic or heterocyclic mono- or polybasic carboxylic, sulfonic or sulfuric acids, e.g. formic acid, acetic acid, propionic acid, pivalic acid, diethylacetic acid, malonic acid, succinic acid, pimelic acid, fumaric acid, maleic acid, lactic acid, tartaric acid, malic acid, citric acid, gluconic acid, ascorbic acid, nicotinic acid, isonicotinic acid, methane- or ethanesulfonic acid, p-toluenesulfonic acid, naphthalenemono- and disulfonic acids or laurylsulfuric acid. Salts with physiologically unacceptable acids, e.g. picrates, can be used for the isolation and/or purification of the compounds of the formula I.

On the other hand, compounds of the formula I with bases (e.g sodium or potassium hydroxide or carbonate) can be converted into the corresponding metal salts, in particular alkali metal or alkaline earth metal salts, or into the corresponding ammonium salts.

Pharmaceutical preparations comprising at least one compound of the formula I and/or one of its physiologically acceptable salts are prepared, in particular, in a non-chemical way. In this case, the compounds of the formula I according to the invention can be brought into a suitable dose form together with at least one solid, liquid and/or semi-liquid excipient or auxiliary and, if appropriate, in combination with one or more other active compounds.

These preparations can be used as medicaments in human or veterinary medicine. Possible excipients are organic or inorganic substances which are suitable for enteral (e.g. oral) or parenteral administration or topical application and do not react with the novel compounds, for example water, vegetable oils, benzyl alcohols, alkylene glycols, polyethylene glycols, glyceryl triacetate, gelatin, carbohydrates such as lactose or starch, magnesium stearate, talc and petroleum jelly. Tablets, pills, coated tablets, capsules, powders, granules, syrups, juices or drops are used, in particular, for oral administration, suppositories are used for rectal administration, solutions, preferably oily or aqueous solutions, furthermore suspensions, emulsions or implants, are used for parenteral administration, and ointments, creams or powders are used for topical application. The novel compounds can also be lyophilized and the lyophilizates obtained used, for example, for the production of injection preparations. The preparations indicated can be sterilized and/or can contain auxiliaries such as lubricants, preservatives, stabilizers and/or wetting agents, emulsifiers, salts for affecting the osmotic pressure, buffer substances, colorants, flavorings and/or one or more other active compounds, e.g. one or more vitamins.

Those of skill will readily appreciate that dose levels can vary as a function of the specific compound, the severity of the symptoms and the susceptibility of the subject to side effects. Some of the specific compounds are more potent than others. Preferred dosages for a given compound are readily determinable by those of skill in the art by a variety of means. A preferred means is to measure the physiological potency of a given compound.

For use in the subject methods, the subject compounds may be formulated with other pharmaceutically active agents, particularly other anti-metastatic, antitumor or anti-angiogenic agents. Angiostatic compounds of interest include angiostatin, enclostatin, carboxy terminal peptides of collagen alpha (XV), etc. Cytotoxic and cytostatic agents of interest include adriamycin, aleran, Ara-C, BICNU, busulfan, CNNU, cisplatinum, cytoxan, daunorubicin, DTIC, 5-FU, hydrea, ifosfamicle, methotrexate, mithramycin, mitomycin, mitoxantrone, nitrogen mustard, velban, vincristine, vinblastine, VP-16, carboplatinum, fludarabine, gemcitabine, idarubicin, irinotecan, leustatin, navelbine, taxol, taxotere, topotecan, etc.

In general, compounds according to the invention are to be regarded as suitable kinase-modulators and especially suitable kinase-inhibitors according to the invention if they show an effect or an activity to one or more kinases, preferably to one or more PKB-kinases that preferably lies, determined as ICso-value, in the range of 100 μmol or below, preferably 10 μmol or below, more preferably in the range of 3 -/mol or below, even more preferably in the range of 1 μmol or below and most preferably in the nanomolar range. Especially preferred for use according to the invention are kinase-inhibitors as defined above/below, that show an activity, determined as IC₅₀-value, to one or more PKB-kinases, preferably including PKBα and/or PKBβ and/or PKBβi and /or PKBγ and /or PKBγi, in the range of 0.5 μmol or below and especially in the range of 0.1 μmol or below. In many cases an IC₅₀-value at the lower end of the given ranges is advantageous and in some cases its highly desirable that the ICso-value is as small as possible or the he ICso-values are as small as possible, but in general ICso-values that lie between the above given upper limits and a lower limit in the region of 0.0001 μmol 0.001 μmol, 0.01 μmol or even above 0.1 μmol are sufficient to indicate the desired pharmaceutical activity. However, the activities measured can vary depending on the respective testing system chosen.

The dose will vary depending on the specific compound utilized, specific disorder, patient status, etc. Typically a therapeutic dose will be sufficient to substantially decrease the undesirable cell population in the targeted tissue, while maintaining patient viability. Treatment will generally be continued until there is a substantial reduction, e.g., at least about 50 %, decrease in the cell burden, and may be continued until there are essentially none of the undesirable cells detected in the body

The compounds of the invention have been shown to have antiproliferative effect in an in vivo xenograft tumor model. The subject compounds are administered to a subject having a hyperproliferative disorders, e.g., to inhibit tumor growth, to decrease inflammation associated with a lymphoproliferative disorder, to inhibit graft rejection, or neurological damage due to tissue repair, etc. The present compounds are useful for prophylactic or therapeutic purposes. As used herein, the term "treating" is used to refer to both prevention of disease, and treatment of pre-existing conditions. The prevention of proliferation is accomplished by administration of the subject compounds prior to development of overt disease, e.g., to prevent the growth of tumors, prevent metastatic growth, diminish restenosis associated with cardiovascular surgery, etc. Alternatively the compounds are used to treat ongoing disease, by stabilizing or improving the clinical symptoms of the patient.

The host, or patient, may be from any mammalian species, e.g., primate sp., particularly human; rodents, including mice, rats and hamsters; rabbits; equines, bovines, canines, felines; etc. Animal models are of interest for experimental investigations, providing a model for treatment of human disease.

The compounds also find use in the specific inhibition of signaling pathway mediated by protein kinases. Protein kinases are involved in signaling pathways for such important cellular activities as responses to extracellular signals and cell cycle checkpoints. Inhibition of specific protein kinases provided a means of inten ening in these signaling pathways, for example to block the effect of an extracellular signal, to release a cell from cell cycle checkpoint, etc. Defects in the activity of protein kinases are associated with a variety of pathological or clinical conditions, where there is a defect in the signaling mediated by protein kinases. Such conditions include those associated with defects in cell cycle regulation or in response to extracellular signals, e.g., immunological disorders, autoimmune and immunodeficiency diseases; hyperproliferative disorders, which may include psoriasis, arthritis, inflammation, endometriosis, scarring, cancer, etc. The compounds of the present invention are active in inhibiting purified kinase proteins preferably PKB kinases, e.g., there is a decrease in the phosphorylation of a specific substrate in the presence of the compound.

The compounds of formula I may also be useful as reagents for the examination of PKB dependent signal transduction pathways in animal and /or cell culture models or any of the clinical disorders listed throughout this application.

There are many disorders associated with a deregulation of cellular proliferation and cell death (apoptose). The conditions of interest include, but are not limited to, the following conditions. The subject compounds are useful in the treatment of a variety of conditions where there is proliferation and/or migration of smooth muscle cells, and/or inflammatory cells into the intimal layer of a vessel, resulting in restricted blood flow through that vessel, e.g., neointimal occlusive lesions. Occlusive vascular conditions of interest include atherosclerosis, graft coronary vascular disease after transplantation, vein graft stenosis, peri-anastomatic prothetic graft stenosis, restenosis after angioplasty or stent placement, and the like.

Diseases where there is hyperproliferation and tissue remodeling or repair or reproductive tissue, e.g., uterine, testicular and ovarian carcinomas, endometriosis, squamous and glandular epithelial carcinomas of the cervix, etc. are reduced in cell number by administration of the subject compounds. The growth and proliferation of neural cells is also of interest.

Tumor cells are characterized by uncontrolled growth, invasion to surrounding tissues, and metastatic spread to distant sites. Growth and expansion requires an ability not only to proliferate, but also to down- modulate cell death (apoptosis) and activate angiogenesis to product a tumor neovasculature.

Tumors of interest for treatment include carcinomas, e.g., colon, duodenal, prostate, breast, melanoma, ductal, hepatic, pancreatic, renal, endometrial, stomach, dysplastic oral mucosa, polyposis, invasive oral cancer, non-small cell lung carcinoma, transitional and squamous cell urinary carcinoma etc.; neurological malignancies; e.g. neuroplastoma, gliomas, etc.; hematological malignancies, e.g., childhood acute leukaemia, non-Hodgkin's lymphomas, chronic lymphocytic leukaemia, malignant cutaneous T-cells, mycosis fungoides, non-MF cutaneous T-cell- lymphoma, lymphomatoid papulosis, T-cell rich cutaneous lymphoid hyperplasia, bullous pemphigoid, discoid lupus erythematosus, lichen planus, etc.; and the like.

Tumors of neural tissue are of particular interest, e.g., gliomas, neuromas, etc. Some cancers of particular interest include breast cancers, which are primarily adenocarcinoma subtypes. Ductal carcinoma in situ is the most common type of noninvasive breast cancer. In DCIS, the malignant cells have not metastasized through the walls of the ducts into the fatty tissue of the breast. Infiltration (or invasive) ductal carcinoma (IDC) has metastasized through the wall of the duct and invaded the fatty tissue of the breast. Infiltrating (or invasive) lobular carcinoma (ILC) is similar to IDC, in that it has the potential metastasize elsewhere in the body. About 10 % to 15 % of invasive breast cancers are invasive lobular carcinomas.

Also of interest is non-small cell lung carcinoma. Non-small cell lung cancer (NSCLC) is made up of three general subtypes of lung cancer. Epidermoid carcinoma (also called squamos cell carcinoma) usually starts in one of the larger bronchial tubes and grows relatively slowly. The size of these tumors can range from very small to quite large. Adenocarcinoma starts growing near the outside surface of the lung and may vary in both size and growth rate. Some slowly growing adenocarcinomas are described as alveolar cell cancer. Large cell carcinoma starts near the surface of the lung, grows rapidly, and the growth is usually fairly large when diagnosed. Other less common forms of lung cancer are carcinoid, cylindroma, mucoepidermoid, and malignant mesothelioma.

Melanoma is a malignant tumor of melanocytes. Although most melanomas arise in the skin, they also may arise from mucosal surfaces or at other sites to which neural crest cells migrate. Melanoma occurs predominantly in adults, and more than half of the cases arise in apparently normal areas of the skin. Prognosis is affected by clinical and histological factors and by anatomic location of the lesion. Thickness and/or level of invasion of the melanoma, mitotic index, tumor infiltrating lymphocytes, and ulceration or bleeding at the primary site affect the prognosis. Clinical staging is based on whether the tumor has spread to regional lymph nodes or distant sites. For disease clinically confined to the primary site, the greater the thickness and depth of local invasion of the melanoma, the higher the chance of lymph node metastases and the worse the prognosis. Melanoma can spread by local extension (through lymphatics) and/or by hematogenous routes to distant sites. Any organ may be involved by metastases, but lungs and liver are common sites.

Other hyperproliferative diseases of interest relate to epidermal hyperproliferation, tissue, remodeling and repair. For example, the chronic skin inflammation of psoriasis is associated with hyperplastic epidermal keratinocyctes as well as infiltrating mononuclear cells, including CD4+ memory T cells, neutrophils and macrophages.

The proliferation of immune cells is associated with a number of autoimmune and lymphoproliferative disorders. Diseases of interest include multiple sclerosis, rheumatoid arthritis and insulin dependent diabetes mellitus. Evidence suggests that abnormalities in apoptosis play a part in the pathogenesis of systemic lupus erythematosus (SLE). Other lymphoproliferative conditions the inherited disorder of lymphocyte apoptosis, which is an autoimmune lymphoproliferative syndrome, as well as a number of leukemia's and lymphomas. Symptoms of allergies to environmental and food agents, as well as inflammatory bowel disease, may also be alleviated by the compounds of the invention.

Above and below, all temperatures are indicated in °C. In the following examples, "customary working-up" for solution reactions means: if necessary, water is added, if necessary, depending on the constitution of the final product, the mixture is adjusted to pHs between 2 and 10 and extracted with ethyl acetate or dichloromethane, the organic phase is separated off, dried over sodium sulfate and evaporated, and the residue is purified by chromatography on silica gel and/or by crystallization.

"Customary working-up" for solid-phase reactions means: the crude reaction is filtered and washed with DMF twice, then successively with methanol and methylene chloride three times, and finally once with methyl tert-butyl ether. The resin is then dried in vacuum.

Mass spectrometry (MS) apparatuses Kratos OMIT and Finnigan LCQ. (M+H)⁺ values or M⁺ values are determined.
