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.
Potent and selective ATP-competitive inhibitor of Checkpoint kinase 1 (Chk1)

Reduction in nucleotide pools through the inhibition of mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) has been demonstrated to effectively reduce cancer cell proliferation and tumour growth. The current study sought to investigate whether this antiproliferative effect could be enhanced by combining
