Description
This application claims the benefit of U.S. provisional patent application 60/753,349, filed on 21/2005 and 60/864,932, filed on 8/11/2006, the disclosures of which are incorporated herein by reference in their entirety.
Technical Field
The present invention relates generally to a novel chemical compound and a method thereof. More particularly, the present invention provides novel carbonylamino pyrrolopyrazoles compounds having protein kinase activity and analogs thereof, and methods of synthesizing and using the same.
Background
Protein kinases are a class of enzymes that catalyze the phosphorylation of hydroxyl groups in specific tyrosine, serine, or threonine residues in proteins. In general, this phosphorylation can significantly alter the function of proteins, and thus protein kinases can play a key role in regulating various cellular processes, including metabolism, cell proliferation, cell differentiation, and cell survival. The mechanisms of these cellular processes provide the basis for target protein kinases for the treatment of disease conditions derived from or involving dysregulation of these cellular processes. Examples of such diseases include, but are not limited to, cancer and diabetes.
Protein kinases can be divided into two classes, Protein Tyrosine Kinases (PTKs) and serine-threonine kinases (STKs). Both PTKs and STKs may be receptor protein kinases or non-receptor protein kinases. PAKs are a class of non-receptor STKs. The p-21-activated protein kinase (PAK) among serine/threonine protein kinases plays an important role in the formation of cytoskeleton and in cell morphogenesis (Daniels et al, Trends biochem. Sci.24: 350-355 (1999); Sells et al, Trends cell. biol.7: 162-167 (1997)). PAK proteins were originally identified by interactions with active small gtpases, Cdc42 and Rac, and homologues of the yeast kinase Ste 20. In addition to modulation of actin cytoskeleton and cell adhesion by Cdc42 and Rac mediation (Daniels et al, Trends biochem. Sci.24: 350-355(1999)), it has been determined that some PAK proteins protect cells from apoptosis (Gnesuta et al, J.biol. chem.276: 14414-14419 (2001); Rudel et al, Science 276: 1571-1574 (1997); Schurmann et al, mol.cell.biol.20: 453-461 (2000)); the pathway of mitogen-activated protein (MAP) kinase regulation (Bagrodia et al, J.biol.chem.270: 27995 27998 (1995); Brown et al, curr.biol.6: 598-; mediate the signaling of T-cell antigen receptors (TCRs) (Yablonski et al, EMBO J.17: 5647-5657(1998)) and respond to DNA damage (Roig et al, J.biol. chem.274: 31119-31122 (1999)). Through the various functions described above, PAK proteins regulate cell proliferation and migration.
U.S. Pat. No. 6,013,500 discloses full-length PAK4 nucleic acid and amino acid sequences and is deposited in GenBank under accession numbers AF005046(mRNA) and AAD01210 (amino acids). It has been reported that modulation of the activity of human PAK4 results in alterations in cellular processes that affect cell growth and adhesion. For example, overexpression of PAK4 in fibroblasts results in morphological changes characterized by oncogenic transformation by inducing anchor-independent growth and inhibition of apoptosis (Gnesuta et al, J.biol.chem.276: 14414-14419 (2001); Qu et al, mol.cell.biol.21: 3523-2533 (2001)). In recent years, studies have also shown that: PAK4 was overexpressed in tumor cell lines in various tissue sources in humans; the expression of the active PAK4 mutant has transforming potential, thus leading to anchor-independent growth of the NIH3T3 cell line; inactive kinase (kinase-inactive) PAK4 efficiently blocks transformation by active Ras and inhibits anchor-independent growth of HCT116 colon cancer cells. These data strongly suggest PAK4 in oncogenic transformation and suggest that PAK4 required for Ras-driven anchor-independent growth in human cancer cells is active (Smeal et al, J.biol.chem.277, 550-558 (2002)). The application demonstrates the in vivo efficacy of compounds that inhibit the PAK4 kinase domain in mice with transplanted tumors.
It is therefore apparent that PAK is an attractive target for the development of effective therapeutic agents for the treatment of disorders associated with abnormal cell growth, particularly cancer.

The "contacting" can be done "in vitro" (i.e., in vitro, in a petri dish, etc.). In vitro, the contacting may include the compound and PK of interest alone, or may include whole cells. Cells can also be stored or grown in cell culture dishes and contacted with the compound in such an environment. In the context of the present invention, the ability of a particular compound to affect a PK-related disorder, i.e., the IC of the compound, can be determined before attempting to use the compound in vivo in a more complex living organism50. For cells in vitro, the skilled artisan knows various methods to contact PK with compounds, including, but not limited to, direct cell micromirror injection and various membrane-penetrating carrier technologies.
"in vitro" refers to a process that is performed in an artificial environment, such as, but not limited to, an in vitro or culture medium.
"in vivo" refers to a process that is performed in a living organism, such as, but not limited to, a mouse, rat, or rabbit.
"PK-related disorders," "PK-induced disorders," and "abnormal PK activity" all refer to conditions characterized by inappropriate (i.e., less than or more often greater than) PK catalytic activity, wherein a particular PK may be a RTK, CTK, or STK. Inappropriate catalytic activity may arise from: (1) PK expression in cells that do not normally express PKs; (2) elevated PK expression leading to undesired cell proliferation, differentiation and/or growth; or (3) reduced PK expression resulting in an undesired reduction in cell proliferation, differentiation and/or growth. Low activity of a PK means that amplification of the gene encodes a particular PK or produces a level of PK activity that may be associated with a cell proliferation, differentiation and/or growth disorder (i.e., one or more of the symptoms of a cell disorder increase in severity as PK levels increase). The low activity is of course in contrast to this, where the severity of one or more of the symptoms of the cellular disorder increases with decreasing PK levels.
"treating" refers to a method of alleviating or eliminating a PK related cellular disorder and/or symptoms associated therewith. In particular for cancer, the term is simply understood to mean either an increase in the average lifespan of an individual suffering from cancer, or a reduction in one or more of the symptoms of the disease.
An "organism" refers to any living body consisting of at least one cell. A living organism can be as simple as a eukaryotic cell, and living complex as a mammal, including a human.
"therapeutically effective amount" refers to the amount of the compound administered that will alleviate one or more of the symptoms of the disorder being treated to some extent. With reference to the treatment of cancer, a therapeutically effective amount refers to an amount that has at least one of the following therapeutic effects:
(1) reducing the size of the tumor;
(2) inhibit (i.e., to some extent, preferably prevent) metastasis of the tumor;
(3) inhibit (preferably prevent) to some extent the growth of the tumor;
(4) to some extent alleviate (preferably eliminate) one or more of the symptoms associated with cancer.
"monitoring" inhibits the observation or detection of the effect of a compound in contact with a cell expressing a particular PK. The observed or detected effect may be a change in the phenotype of the cell, a change in the catalytic activity of the PK or a change in the interaction of the PK with a natural binding partner. Techniques for observing or detecting the above-mentioned effects are well known in the art. The effect is selected from the group consisting of a change or lack of change in cell phenotype, a change or lack of change in catalytic activity of the protein kinase, or a change or lack of change in interaction of the protein kinase with a natural binding partner in a final aspect of the invention.
"cellular phenotype" refers to the appearance of a cell or tissue, or the biological function of a cell or tissue. Examples of cellular phenotypes are cell size, cell growth, cell proliferation, cell differentiation, cell survival, apoptosis and nutrient uptake and use. The above phenotypic characteristics may be measured by techniques well known in the art.
"native binding partner" refers to a polypeptide that binds to a particular PK in a cell. Natural binding partners may play a role in signal propagation during PK-mediated signal transduction. As the concentration of the PK/natural binding partner complex increases or decreases, it may appear that the interaction of the natural binding partner with the PK itself changes, and thus a change in the ability of the PK to mediate signal transduction may be observed.

Detailed Description
The compounds of formulae I, II, III and IIIa may be prepared by some synthetic routes in Scheme 1(Scheme 1) and Scheme 2(Scheme 2). In scheme 1 and scheme 2 and the following description, "BOC", "Boc" or "BOC" means N-tert-butoxycarbonyl, DCM means CH2Cl2DIPEA (also known as Hunig's base) means diisopropylethylamine, DMA means dimethylamine, "DMF" means dimethylformamide, "DMSO" means dimethylsulfoxide, Et means-CH2CH3"MTBE" means methyl tert-butyl ether, NMP means 1-methyl-2-pyrrolidone, TEA means triethylamine, TFA means trifluoroacetic acid, and THF means tetrahydrofuran. Although schemes 1 and 2 and the description refer to compound I, schemes 1 and 2 and the description apply equally to compounds II, II and IIIa
Scheme 1 represents the synthesis of intermediate I (g) for the preparation of compounds of formula I. The amino group of the substituted amino acid I (a) is alkylated to give compound I (b). This can generally be accomplished by treating compound i (a) with an alkylating agent in the presence of a base. Activated electrophilic double bond groups are commonly used alkylating agents. Typical reaction conditions for alkylation of i (a) with an activated electrophilic double bond group are that i (a) is treated with an activated double bond group in the presence of a strong base. Subsequent water work-up gives compound i (b). Then the amino group of compound I (b) is protected with a boc group to give compound I (c). This can generally be accomplished by treating compound i (b) with Boc reagent in the presence of a base. Typically, the compound I (b) is added to Me4In the presence of NOH in MeCN as solventBy (Boc)2And O, treating. The carboxylic acid group of compound i (c) is then converted to the methyl ester of compound i (d). Typical conditions for converting carboxylic acid groups to methyl ester groups are treatment of I (c) with methyl iodide in the presence of a base in DMF. Then, compound i (d) undergoes intramolecular aldol condensation to give compound i (e). This can generally be done by treating compound i (d) with a strong base in an aprotic solvent. Typically, the compound I (d) is treated with t-BuOK in toluene. Subsequent water work-up gives compound i (e). Then, compound i (e) undergoes a 2+3 cyclization reaction with the hydrazine group, thereby forming compound i (f). Typical conditions for the cyclization are reflux of compound i (e) with hydrazine and acetic acid in EtOH. The free base pyrrole nitrogen in compound i (f) is then acylated to give compound i (g). Typical conditions for acylation are the treatment of compound i (f) with chloroethyl carbonate in THF.
More detailed synthesis conditions for compound i (g) of scheme 1 can be found in U.S. patent application 2003/0171357 and PCT application WO02/12242, which are incorporated herein by reference.
Scheme 2 shows two routes for preparing compounds of formula I starting from intermediate I (g). In the first pathway of scheme 2, Compounds I (g) and R1The electrophilic groups undergo nucleophilic reactions. This nucleophilic reaction may be one of an acylation reaction, an alkylation reaction, a sulfonation reaction, a reductive amination reaction, or some other reaction that performs amine functionalization. Typical acylation reaction conditions are to subject compound I (g) to reaction with, for example, R in the presence of a base such as 2 equivalents of DIPEA in a solvent such as dichloromethane1-COCl acylating agent. The reaction mixture was stirred between 0 ℃ and room temperature for 12 hours. Subsequent water work-up gives compound i (h). Then, the Boc group on the pyrrole nitrogen of compound I (h) is removed to give compound IAn item I (i). This can generally be accomplished by treating I (h) with a strong acid. Typical reaction conditions are that compound i (h) is treated with dioxane and 4N HCl in DCM. Subsequent water work-up gives compound i (i). Then, the pyrrole NH in compound i (i) is acylated to give chloroformate i (j). This can be accomplished using phosgene, triphosgene and some equivalents. Typical reaction conditions are that I (i) is treated with 2 equivalents of triphosgene in DCM at 0 ℃ for 4 hours. Subsequently, saturated NaHCO was used3Mild base work-up and purification was carried out to give compound i (j). Then, compound I (j) is taken as R1And (4) processing the nucleophilic group. The nucleophile may be an alcohol, an amine or one of several other functional groups that may react with chloroformate i (j). Typical reactions include: will I (j), at such as K2CO3With a nucleophile such as 1.5 equivalents of an alcohol in a solvent such as DME in the presence of 2 equivalents of a base. The reaction was heated to 80 ℃ for 8 hours and the solvent was removed. Alternatively, i (j) may be treated with 1.5 equivalents of amine in a solvent such as THF in the presence of 1 equivalent of a base such as DIPEA. Subsequent work-up and purification in the presence of a base such as TEA in a protic solvent such as methanol gives the compound of formula I.
Or, the compounds I (i) are then reacted with R4Nucleophilic reaction of the electrophile to give compound i (k). The nucleophilic reaction for carrying out the above-mentioned conversion may be an alkylation reaction, an acylation reaction, a sulfonation reaction, or a reductive amination reaction. The acylation of I (i) is carried out by treating compound I (i) with an acylating agent in the presence of a base to give I (k). Typical reaction conditions are that compound i (i) is mixed with an excess of base such as DIPEA in DCM and the resulting solution is added to the isocyanate at 0 ℃. The reaction was stirred for 2 hours followed by aqueous work-up to give compound i (k). Removing the ethyl ester protecting group from the pyrrole nitrogen of compound I (k) to obtain compound I. This can generally be done by treating compound i (k) with a base. Typical reaction conditions are such that the compound I (k) is present in 2-3 equivalents of LiOHReflux in dioxane and DCM in the presence. Followed by aqueous work-up to give the compounds of the formula I.
In the second route of scheme 2, the Boc group on the pyrrole nitrogen is removed to give compound I (l). This can generally be exemplified by treating compound i (g) with a strong acid. Typical reaction conditions are that compound i (g) is treated with 4N HCl in dioxane and DCM. Followed by water work-up to give compound i (l). Then, the compounds I (l) may be reacted with R4Nucleophilic reaction of the electrophile to give compound i (m). Because of the-NH linkage to the pyrrole in the compounds I (l)2The group is less reactive than the pyrrole nitrogen of I (l), so that the conversion of I (I) to I (m) can be carried out without protecting the pyrrole-NH of the compound I (l)2A group. The nucleophilic reaction used in the above conversion examples may be alkylation, acylation, sulfonation, reductive amination. Relatively mild reaction conditions are preferred to achieve selectivity of the above reaction. The acylation of I (l) is carried out by treating compound I (l) with an acylating agent in the presence of a base to give I (m). Typical reaction conditions are that compound i (l) is mixed with an excess of base such as DIPEA in DCM and the resulting solution is added to the isocyanate at 0 ℃. The reaction was maintained at 0 ℃ for about 2 hours followed by aqueous workup to give compound i (m).
Then, compounds I (m) and R1The electrophilic groups undergo nucleophilic reactions. The nucleophilic reaction may be one of an acylation reaction, an alkylation reaction, a sulfonation reaction, a reductive amination reaction, or some other reaction performed by an amine functional group. Typical acylation reaction conditions are to compound I (m) in the presence of a base such as 2 equivalents of DIPEA in a solvent such as dichloromethane with a base such as R1Treatment with an acylating agent for-NCO for 2 hours. Alternatively, I (m) may be dissolved with a base such as 2 equivalents of DIPEA in a solvent such as 1, 2-dichloroethane1-COOR (wherein, R1An activating group such as p-nitrophenyl). Subsequent water aftertreatmentTo give compound i (n). The ethyl ester protecting group on the pyrazole nitrogen of compound I (n) is typically removed with a base to give the free base compound I. Typical reaction conditions are that compound I (n) is mixed with TEA in a protic solvent such as methanol and purified to give the compound of formula I.
Alternatively, the ethyl ester protecting group on the pyrazole nitrogen of compound i (m) is removed to provide the free base compound i (o). This can generally be done by treating compound i (m) with a base. Typical reaction conditions formula compound i (m) is refluxed in dioxane and DCM in the presence of 2-3 equivalents of LiOH. Followed by aqueous work-up to give compound i (o). Then, compounds I (o) and R1The electrophilic groups undergo nucleophilic reactions. The nucleophilic reaction may be one of an acylation reaction, an alkylation reaction, a sulfonation reaction, a reductive amination reaction, or some other reaction performed by an amine functional group. Typical acylation reaction conditions are to subject compound I (o) to reaction with a base such as 2 equivalents of DIPEA in a solvent such as dichloromethane, with a base such as R1-COCl acylating agent. The reaction mixture was stirred for 4 hours, followed by aqueous workup and purification to give the compound of formula I.

Prior to use in dry powder or suspension formulations, the drug substance is micronized into a size suitable for delivery by inhalation (typically less than 5 microns). This may be achieved by any suitable comminution method, such as spiral jet milling, fluid bed jet milling, supercritical fluid processing to form nanoparticles, high pressure homogenisation or spray drying.
Capsules (made, for example, from gelatin or HPMC), blisters and cartridges for use in an inhaler or insufflator may be formulated containing a powder mix of a compound of the invention, a suitable powder base such as lactose or starch and a performance modifier such as l-leucine, mannitol or magnesium stearate. Lactose can be in anhydrous form or in monohydrate form, preferably in monohydrate form. Other suitable excipients include, glycosides, dextrose, maltose, sorbitol, xylitol, fructose, sucrose, and trehalose.
Suitable solution formulations using electro-hydraulics to generate a fine mist in an aerosolizer may contain 1 μ g to 20mg of a compound of the invention per actuation, and the actuation volume may vary between 1 μ l to 100 μ l. A typical formulation may include a compound of the invention, propylene glycol, sterile water, ethanol, and sodium chloride. Other solvents that may be used in place of propylene glycol include glycerol and polyethylene glycol.
Suitable flavoring agents, such as menthol and levomenthol, or sweetening agents, such as saccharin or saccharin sodium, may be added to those formulations of the invention for inhalation/intranasal administration.
Formulations for inhalation/intranasal administration may be formulated for immediate release and/or modified release, for example, of poly (DL-lactic-co-glycolic acid) (PGLA). Modified release formulations include delayed release, sustained release, pulsatile release, controlled release, targeted release and programmed release.
In the case of dry powder inhalers and aerosols, the dosage units are determined by a valve delivering a metered dose of medicament. The units of the invention are generally designed to administer a metered dose or "smoke volume" containing the desired amount of the compound of the invention. The total daily dose may be administered in a single dosage form or, more often, in divided daily doses.
Intrarectal/intravaginal administration
The compounds of the invention may be administered rectally or vaginally, for example in the form of suppositories, pessaries or enemas. Cocoa butter is a conventional suppository base, but various alternatives may be used as appropriate.
Formulations for rectal/vaginal administration may be formulated for immediate release and/or modified release. Modified release formulations include delayed release, sustained release, pulsatile release, controlled release, targeted release and programmed release.
Ophthalmic drug delivery
The compounds of the invention may also be administered directly to the ear or eye, usually as micronized suspension droplets or as a solution in isotonic, PH-adjusted sterile saline. Other formulations suitable for ophthalmic and otic administration include ointments, biodegradable (e.g., absorbable gel sponges, collagen) and non-biodegradable (e.g., silicone) implants, patches, lenses, and microparticulate or vesicular systems, such as vesicles (niosomes) or liposomes. Polymers such as crosslinked polyacrylic acid, polyvinyl alcohol, hyaluronic acid, cellulose polymers (e.g., hydroxypropyl methylcellulose, hydroxyethyl cellulose, or methyl cellulose), or heteropolysaccharide polymers (e.g., gelan gum) may be incorporated with preservatives such as benzalkonium chloride. The formulations described above can also be delivered by ionophoresis.
Formulations for ocular/otic administration may be formulated for immediate release and/or modified release. Modified release formulations include delayed release, sustained release, pulsatile release, controlled release, targeted release and programmed release.
Other techniques
The compounds of the invention may be combined with soluble macromolecular entities such as cyclodextrins and suitable derivatives thereof or polyethylene glycol containing polymers to improve their solubility, dissolution rate, taste masking, bioavailability and/or stability for use in any of the above-described modes of administration.
For example, drug-cyclodextrin complexes are found to be generally useful in most dosage forms and routes of administration. Inclusion and non-inclusion complexes may be used. Another method of direct complexation with drugs is that cyclodextrins may be used as adjuvants, i.e. as carriers, diluents or solubilisers. The most commonly used for these purposes are alpha-, beta-and gamma-cyclodextrins, examples of which may be found in PCT applications WO 91/11172, WO 94/02518 and WO 98/55148, the disclosures of which are incorporated herein by reference.
Dosage form
The amount of active compound administered will depend on the patient to be treated, the severity of the disorder or condition, the rate of administration, the distribution of the compound and the diagnosis of the physician. However, effective dosages will generally be in the range of about 0.001 to about 100mg/kg body weight per day, preferably 0.01 to about 35mg/kg per day, in single or divided dosage forms. For a 70kg adult, the amount is from about 0.07 to about 7000 mg/day, preferably from about 0.7 to about 2500 mg/day. In some cases dosage ranges below the lower limit of the aforesaid range are more appropriate, while in other cases still higher doses may be employed without causing any harmful side effects, the aforesaid higher doses usually being divided into several lower doses to be taken within a day.
Medicine bag
Since it is desirable to administer a combination of active compounds, for example, for the treatment of a particular disease or condition, it is also within the scope of the present invention that two or more pharmaceutical compositions, at least one of which comprises a compound of the present invention, may conveniently be combined in a kit suitable for simultaneous administration of the compositions. Thus, a kit of the invention comprises two or more separate pharmaceutical compositions (at least one of which comprises a compound of the invention), and means for separately holding the compositions, such as a container, separate bottle or separate tin foil packet. Examples of the above-mentioned kits are common blister packs for packaging tablets, capsules and the like.
The kit of the invention is particularly suitable for administration of different dosage forms (e.g. oral and parenteral dosage forms), for administration of the individual compositions at different dosing intervals, or for the quantitative titration of the individual compositions with one another. To aid compliance, kits often include instructions for taking the medication and may provide so-called memory assistance.

Bioassay, Ki data, cell assay data and in vivo efficacy data
Cloning, expression and purification of recombinant PAK4 kinase domain (PAK4 KD): the cDNA encoding PAK4 was amplified by PCR from an EST clone (#12) (purchased from Research Genetics). In PCR, P33(ACATATG TCC CATGAGCAGT TCCGGGCTGCCCTGCAGCT) and P34(CTCA TGGGTGCTTC AGCAGCTCGGCTGCCGTGGC) were used as 5 'and 3' primers, respectively. The PCR amplified product was cloned into a Topo vector (Invitrogen Inc.) and verified by DNA sequencing. Then, PAK4KD was subcloned into expression plasmids pET28a (+), pET24a (+) or pGST4.5. The recombinant plasmid containing PAK4KD was transformed into BL21(DE3) cells for recombinant protein expression. The production of PAK4KD was induced by adding IPTG to the cells at 27 ℃. Cells were then harvested and lysed for protein purification. Ni-NTA columns (pET28a (+), pET24a (+)) and glutathione column (pGST4.5) were used for purification. The purified protein was then subjected to a thrombin assay to cleave the inherent N-termination tag from the expression plasmid, thus yielding PAK4KD for the Ki assay of the invention. PAK4 kinase domain enzyme assay conditions: by PAK4KD is determined by the ability of the phosphate residue to be catalyzed by nucleoside triphosphates to be transferred to the amino acid side chain (amino acid sequence EVPRRKSLVGTPYWM) of a commercially available polypeptide. Conversion of ATP to ADP is accompanied by a catalytic reaction. PAK4KD catalyzes the process of ADP production from ATP in association with NADH oxidation by the activation of Pyruvate Kinase (PK) and Lactate Dehydrogenase (LDH). Molecular devices SPECTRAMAX 190 in combination with Biomec FX was used at 340nm (e340 ═ 6.22 cm)-1mM-1) Monitoring NADH to NAD by reduction in absorbance+The transformation of (3). A typical reaction solution comprises 2mM phosphoenolpyruvate (phosphoenol pyruvate), 0.35mM NADH, 10mM MgCl21mM DTT, 0.4mM polypeptide (EVPRRKSLVGTPYWM), 0.04mM ATP, 1 unit/mL PK, 1 unit/mL LDH, 0.01% Tween 20 in 50mM HEPES, pH 7.5. The assay was initiated by the addition of 25nM PAK4 KD. The Ki of the PAK kD for each compound of the invention (inhibitor) was calculated based on the fold of the percent inhibition of the inhibitor at different inhibitor concentrations. The polypeptide (amino acid sequence EVPRRKSLVGTPYWM) was purchased from American Peptide Company. NADH, MgCl2HEPES, DTT, ATP and PK/LDH were purchased from Sigma. Tween 20 was purchased from Calbiochem.
A sandwich ELISA method (sandwich ELISA method) was used to measure the activity of PAK4 kinase in whole cells. The level of PAK 4-dependent phosphorylation of GEF-H1b can be determined by monitoring the binding of phosphospecific antibodies (phosphospecific antibodies) to GEF-H1 b. The modified HEK 293 cell line was used in biological assays and has been designed to overexpress GEF-H1b and the Kinase Domain (KD) of PAK 4. KD of PAK4 in this cell line can be induced by tetracycline (Trex system, Invitrogen). This cell line was named TR-293-KDG. To construct the phosphorylation event in GEF-H1, cells were induced to express PAK4KD using doxycycline. Negative control wells were not induced. The effect of the candidate substance is measured by its ability to block the phosphorylation time.
ELISA plates were prepared by the following method: each plate was precoated with a capture antibody (a-HA-labeled mouse monoclonal antibody), blocked with BSA, and washed in 0.1% tween 20 in tris-buffered saline (TBST). TR-293-KDG cells were seeded on tissue culture plates (pre-coated with poly-D-lysine). TR-293-KDG cells were induced to express PAK4KD overnight with doxycycline and then & concurrently treated with candidate substance or diluent for another 3 hours, exposure was continued. Then, cells were lysed with modified RIPA buffer supplemented with protease inhibitors. Fresh whole cell lysates were then spiked into the ELISA plates for 2 hours. Between all subsequent steps, plates were washed 4 times with TBST. The probe antibody (recognizing the phosphorus-specific epitope on GEF-H1 b) was added for 1 hour followed by the enzyme-linked goat α -rabbit secondary antibody for 45 minutes. The enzyme-linked antibody was stained with peroxide. After 30 minutes of induction, absorbance at 405nm for abts (moss inc) was read using a spectrophotometer. EC50 values were calculated by sigmoidal curve fitting using four parameter analysis.

The compound 3- [ (4-fluorobenzoyl) amino ] -6, 6-dimethyl-4, 6-dihydropyrrolo [3, 4-c ] pyrazole-5 (1H) -carboxylic acid (1S) -2- (dimethylamino) -1-phenylethyl ester of example 2 has an in vivo tumor growth inhibiting effect on HCT116 human colorectal cancer tumor xenografts in athymic mice. Details are provided below.
Materials and preparation: the HCT116 cell line was obtained from American Type CultureCo (ATCC, Bethesda, Md.). The cells were grown as individual monolayers in McCoy media supplemented with 10% FBS (from Life Technologies, Inc., Bethesda, Md.) and 5% CO maintained at 37 deg.C2Under a humid atmosphere. Tumor cells were harvested near fusion by culture with 0.05% insulin-EDTA and transplanted into athymic mice. The cells were pelleted at 450Xg for 5-10 minutes and the cell pellets were resuspended in serum-free McCoy medium supplemented with 50% matrigel. On day 0, tumor cells (1 × 106 cells/animal) were transplanted into the hind flank region of each mouse and grown to the indicated size before administration of the compounds of each experiment.
Inhibiting tumor growth: when the tumor reaches about 200mm3At size (d), treatment is initiated. The compound or vehicle of example 2 (methylcellulose, MC) was administered in oral gavage 10mL/kg daily or every other day. Tumors were measured using a Vernier caliper and the formula length x width2X 0.4 to calculate the tumor volume. Tumor volumes were measured on selected days and the median tumor volume for each group of 12 animals was expressed as median ± SEM. Grinding machineAt the end of the study (day 39), the highest percentage of tumor growth inhibition was calculated as 100 x (tumor volume final-tumor volume initial) for each group treated with example 2 and was settled as 100 x (tumor volume initial) for the vehicle groupFinally, the product is processedTumor volumeInitial) And when the median tumor volume reached 1250mm3Tumor growth delay was calculated as: median tumor volumeMedicine for curing diabetes Therapeutic groupMedian tumor volumeControl group。
And (3) tumor growth delaying: when the tumor reached-200 mm on day 113Treatment with the compound of example 2 was started and continued for 28 days until tumors of the control group reached the evaluation size (1250 mm)3). To assess the retardation of tumor growth, tumor measurements were continued until tumors in the treated group reached the assessment size (1250 mm)3). The compound of example 2 was administered to tumor-bearing mice as a 10mL/kg volume solution of MC by oral gavage and compared to vehicle alone at the same volume. Oral administration of the compound of example 2 at 50 mg/kg/day or 75 mg/kg/alternate day, statistically had 50% or 37% significant tumor growth inhibition (p 0.05), respectively, compared to vehicle-treated controls (fig. 1). In addition, a delay in tumor growth of 12.2 days or 9.8 days at a dose level of 50 mg/kg/day or 75 mg/kg/alternate day, respectively, was observed. Mice administered the compound of example 2 throughout the 28 day treatment cycle generally appeared healthy and continued to gain weight.
The tumor growth inhibitory effect and tumor growth retardation results of the compound 3- [ (4-fluorobenzoyl) amino ] -6, 6-dimethyl-4, 6-dihydropyrrolo [3, 4-c ] pyrazole-5 (1H) -carboxylic acid (1S) -2- (dimethylamino) -1-phenylethyl ester of example 2 are summarized in the following table and fig. 1.

As can be seen in figure 1, the compound of example 2 inhibited/delayed the growth of HCT116 human colorectal cancer tumor xenografts in athymic mice. When the mean tumor size reached 200mm on day 113The compound of example 2 was orally administered initially at 50 mg/kg/day (QD) or 75 mg/kg/alternate day (QOD) and continued until day 39 to stop treatment. Tumor volumes were measured on selected days, with median tumor volumes for 10 animals per group being median ± SEM. At selected time points, 50&ANOVA p < 0.01 in the 75mg/kg group compared to the vehicle control group.
