INDOLYL- PYRIDONE DERIVATIVES HAVING CHECKPOINT KINASE 1 INHIBITORY ACTIVITY.

摘要

Compounds of formula (I) have checkpoint kinase 1 (CHK1 ) inhibitory activity: wherein R1, R2, R5 and R6 are independently selected from hydrogen, hydroxy, methyl, trifluoromethyl, hydroxymethyl, methoxy, trifluoromethoxy, methylamino and dimethylamino; R3, and R4 are independently selected from hydrogen, hydroxy, C1-C3 alkyl, fluoro-(C1-C3)-alkyl, hydroxy-(C1C3)-alkyl, C1-C3 alkoxy, fluoro-(C1-C3)-alkoxy, hydroxy-(C1-C3)-alkoxy, -N(R11)-R12, -AIk-N(R11)-R12, -0-AIk-N(R11)-R12, -C(=O)OH, carboxy-(C1-C3)-alkyl, or -C(=O)-NH-R13; AIk is a straight or branched chain divalent C1-C6 alkylene radical; R7 and R8 are independently selected from hydrogen, hydroxy, or C1-C3 alkoxy; X is a straight chain divalent C1-C3 alkylene radical, optionally substituted on one or more carbons by R9 and/or R10; W is selected from -C(=O)-N(-R16)- or -N(-R17)-C(=O)-; Y is hydrogen, C1-C3 alkyl, C1-C3 alkoxy, or halo; and Q is selected from optionally substituted phenyl, optionally substituted cyclohexyl, or an optionally substituted 6-membered monocyclic heteroaryl ring.
