Description: 4-ALKENYL ( AND ALKYNYL ) OXINDOLES AS INHIBITORS OF CYCLIN-DEPENDENT KINASES, IN PARTICULAR CDK2 Uncontrolled cell proliferation is the hallmark of cancer. Cancerous tumor cells typically have some form of damage to the genes that directly or indirectly regulate the cell-division cycle. Cyclin-dependent kinases (CDKs) are enzymes which are critical to cell cycle control. See, e.g., Coleman et al., "Chemical Inhibitors of Cyclin-dependent Kinases," Annual Reports in Medicinal Chemistry, vol. 32, 1997, pp. 171 -179. These enzymes regulate the transitions between the different phases of the cell cycle, such as the progression from the Gi phase to the S phase (the period of active DNA synthesis), or the progression from the G 2 phase to the M phase, in which active mitosis and cell-division occurs. See, e.g., the articles on this subject appearing in Science, vol. 274, 6 December 1996, pp 1643-1677. CDKs are composed of a catalytic CDK subunit and a regulatory cyclin subunit. The cyclin subunit is the key regulator of CDK activity, with each CDK interacting with a specific subset of cyclins: e.g. cyclin A (CDK1 , CDK 2). The different kinase/cyclin pairs regulate progression through specific stages of the cell cycle. See, e.g., Coleman, supra. Aberrations in the cell cycle control system have been implicated in the uncontrolled growth of cancerous cells. See, e.g., Kamb, "Cell-Cycle Regulators and Cancer," Trends in Genetics, vol. 11 , 1995, pp. 136-140; and Coleman, supra. In addition, changes in the expression of or in the genes encoding CDK's or their regulators have been observed in a number of tumors. See, e.g., Webster, "The Therapeutic Potential of Targeting the Cell Cycle," Exp. Opin. Invest. Drugs, Vol. 7, pp. 865-887 (1998), and references cited therein. Thus, there is an extensive body of literature validating the use of compounds inhibiting CDKs as anti- proliferative therapeutic agents. See, e.g. U.S. Patent No. 5,621 ,082 to Xiong et al; EP 0 666 270 A2; WO 97/16447; and the references cited in Coleman, supra, in particular reference no. 10. Thus, it is desirable to identify chemical inhibitors of CDK kinase activity. It is particularly desirable to identify small molecule compounds that may be readily synthesized and are effective in inhibiting one or more CDKs or CDK/cyclin complexes, for treating one or more types of tumors. Indolinone (also known as oxindole) compounds asserted to be useful in the regulating abnormal cell proliferation through tyrosine kinase inhibition are disclosed in WO 96/401 16, WO 98/07695, WO 95/01349, WO 96/32380, WO 96/22976, WO 96/16964 (tyrosine kinase inhibitors), and WO 98/50356 (2- indolinone derivatives as modulators of protein kinase activity). Oxindole derivatives have also been described for various other therapeutic uses: 5,206,261 (improvement of cerebral function); WO 92/07830 (peptide antagonists); EP 580 502 A1 (antioxidants). There continues to be a need for easily synthesized, small molecule compounds for the treatment of one or more types of tumors, in particular through regulation of CDKs. It is thus an object of this invention to provide such compounds and compositions containing such compounds. The present invention is directed to novel 4-alkenyl- and 4-alkynyl oxindoles which inhibit cyclin-dependent kinases (CDKs), in particular CDK2. These compounds and their pharmaceutically acceptable salts, and prodrugs of said compounds, are anti-proliferative agents useful in the treatment or control of cell proliferative disorders, in particular cancer.

These effects indicate that the compounds of the present invention are useful in treating cancer, in particular solid tumors such as breast and colon tumors. CDK2 FlashPlate Assay To determine inhibition of CDK2 activity, purified recombinant retinoblastoma (Rb) protein was coated on 96 well FlashPlates (New England Nuclear, Boston, MA). Rb is a natural substrate for phosphorylation by CDK2 (Herwig and Strauss Eurr. J. Biochem., Vol. 246 (1997) pp. 581-601 and references therein). Recombinant active human Cyclin E/CDK2 complexes were partially purified from extracts of insect cells. The active Cyclin E/CDK2 was added to the Rb-coated FlashPlates along with 33 P-ATP and dilutions of test compounds. Plates were incubated for 25 minutes at room temperature with shaking, then washed and counted in the Topcount scintillation counter (Packard Instrument Co., Downers Grove, IL). Dilutions of test compounds were tested in duplicate in each assay. The percent inhibition of Rb phosphorylation, which is a measure of the inhibition of CDK2 activity, was determined according to the following formula: 100 x test compound - nonspecific"] total - nonspecific s where "test compound" refers to the average counts per minute of the test duplicates, "nonspecific" refers to the average counts per minute when no Cyclin E/CDK2 was added, and "total" refers to the average counts per minute when no compound was added. The results of the foregoing in vitro experiments are set forth in Tables I A and I B below. Each of the compounds in Table I A had IC 5 o less than 4.0 μM. TABLE I A TABLE I A - (Cont.) AA <4.0 BB <4.0 DD <4.0 FF <4.0 HH <4.0 TABLE I B Cell-Based Assays The estrogen receptor negative epithelial breast carcinoma line (MDA-MB- 435) was purchased from American Type Cell Culture Collection (ATCC; Rockville, MD) and was grown in the medium recommended by ATCC. For analysis of the effect of the test compounds on growth of these cells, the cells were plated at 2000 cells per well in a 96-well tissue culture plate, and were incubated overnight at 37°C with 5% CO2. The next day, the test compounds were dissolved in 100% dimethyl sulfoxide (DMSO) to yield a 10 mM stock solution. Each compound was diluted with sterile medium to 1 mM in a sufficient quantity to yield a final concentration of 120 μM. The compounds were then serially diluted in medium with 1.2% DMSO. One-fourth final volume of the diluted compounds was transferred to 96 well plates. Test compounds were assayed in duplicate. DMSO was added to a row of "control cells" such that the final concentration of DMSO in each well was 0.3%. Wells to which no cells were added served as the "blank." Wells to which no inhibitor was added served as "no inhibitor control". The plates were returned to the incubator, and 5 days post addition of test compound, were analyzed as described below. 3-(4,5-Dimethylthiazole-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (thiazolyl blue; MTT) was added to each well to yield a final concentration of 1 mg/mL. The plates were then incubated at 37°C for 3 hours. The plates were centrifuged at 1000 rpm for 5 minutes prior to aspiration of the MTT-containing medium. The MTT-containing medium was then removed and 100 μL 100% ethanol was added to each well to dissolve the resulting formazan metabolite. To ensure complete dissolution, plates were shaken for 15 minutes at room temperature. Absorbencies were read in a microtiter plate reader (Molecular Dynamics) at a wavelength of 570 nm with a 650 nm reference. Percent inhibition was calculated by subtracting the absorbance of the blank (no cell) wells from all wells, then subtracting the division of the average absorbance of each test duplicate by the average of the controls from 1.00. Inhibitory concentrations (IC50) were determined from the linear regression of a plot of the logarithm of the concentration versus the percent inhibition. The colon carcinoma line SW480 also was obtained from the ATCC and was tested according to the same protocol provided above with the following modification: cell line SW480 was plated at 1000 cells per well and analyzed at 4 days post addition of test compound. The results of the foregoing in vitro tests are set forth below in Tables II and III.
