Description: PF-00477736, also known as PF-477736, is a potent CHK1 inhibitor with potential chemopotentiation activity. PF-477736 inhibits chk1, an ATP-dependent serine-threonine kinase that is a key component in the DNA replication-monitoring S/G2 checkpoint system. By overriding the last checkpoint defense against DNA damaging agent-induced lethal damage, chk1 inhibitor PF-477736 may potentiate the antitumor efficacy of various chemotherapeutic agents against tumor cells with intrinsic checkpoint defects.
