PF-477736, >=98% (HPLC)

Application

PF-477736 has been used as a checkpoint protein 1 (CHK1) inhibitor to study the effect of CHK1 in cell cycle regulation in primary breast and lung primary epithelial cells.

Biochem/physiol Actions

PF-00477736 is a potent, selective ATP-competitive small-molecule inhibitor that inhibits Chk1 with a Ki of 0.49 nM. The compound abrogates cell cycle arrest induced by DNA damage and enhances cytotoxicity of clinically important chemotherapeutic agents, including gemcitabine and carboplatin.

PF-477736 may be effectively used to resensitize platinum resistant ovarian cancer cells. PF-477736 alone or in combination with other chemotherapeutic agents may be used to treat triple-negative breast cancer.
