GDC-0575 is an inhibitor of checkpoint kinase 1 (Chk1; IC50 = 1.2 nM).1 It is greater than 30-fold selective for Chk1 over a panel of more than 450 wild-type and mutant kinases. GDC-0575 (500 nM) enhances apoptosis induced by cytarabine (Item No. 16069) in HL-60, KG-1, U937, and ML-1 human acute myeloid leukemia (AML) cells.
