Biological Activity

PF 477736 is a selective checkpoint kinase 1 (Chk1) inhibitor (Ki values are 0.49 and 47 nM for Chk1 and Chk2 respectively). Abrogates cell cycle arrest at S and G2-M checkpoints; sensitizes cells to DNA damage. Enhances docetaxel (Cat. No. 4056) efficacy in tumor cells and xenografts.
