Catalog Number: 4277
Alternate Names: PF-0044736
Chemical Name: (R)-α-Amino-N-[5,6-dihydro-2-(1-methyl-1H-pyrazol-4-yl)-6-oxo-1H-pyrrolo[4,3,2-ef][2,3]benzodiazepin-8-yl]-cyclohexaneacetamide
Biological Activity
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.
