<p>Disclosed are compounds of the formula (I) wherein: R2 is hydrogen, alkyl, or cycloalkyl; R3 is hydrogen, lower alkyl, lower alkoxy, halogen, trifluoromethyl, lower alkynyl, lower alkenyl, nitrile, nitro, -COR4, -CO2R?4, -CONR4R5, -CONR4OR5, -SO¿2NR?4R5, -SO¿2NR?4R5, -SO¿2R4, -SO3R4, formula (II), or -NR4R5; Y is N or CR7; R9 is lower alkyl, haloalkyl, or aryl; X and Z are independently hydrogen, halogen, lower alkyl, lower alkoxy, trifluoromethyl, hydroxy, nitrile, nitro, -NR4R5, -N(O)R?4R5, -NR4R5R6W, -SR4¿, -C(O)R4, -CO2R?4, -CONR4R5, -SO¿2NR?4R5, -SO¿2R4, -SO3R4, P(O)(OR4)(OR5), -T(CH¿2)mQR?4, -C(O)T(CH¿2)mQR?4, or -NR4C(O)T(CH¿2)mQR?5; m is 1 to 6. These compounds are useful for treating cell proliferative disorders, such as cancer, atherosclerosis, and restenosis. These compounds are potent inhibitors of cyclin-dependent kinases (cdks) and growth factor-mediated kinases.</p> |
