Abstact

CHK-1 is one of the key enzymes regulating checkpoints in cellular growth cycles. Novel 4-(amino-alkylamino)-3-benzimidazole-quinolinones were prepared and assayed for their ability to inhibit CHK-1. These compounds are potent cell permeable CHK-1 inhibitors and showed synergistic effect with a DNA-damaging agent, camptothecin.
