    Product Description

    KU-0058948 is an inhibitor of poly(ADP-ribose) polymerase 1 (PARP1) and PARP2 (IC50s = 3.4 and 1.5 nM, respectively).1 It is selective for PARP1 over PARP3, PARP4, and tankyrase (IC50s = 40, 1,200, and >10,000 nM, respectively). It also selectively inhibits the survival of mouse embryonic stem cells lacking Brca1 or Brca2 over mouse embryonic stem cells expressing wild-type Brca1 or Brca2. KU-0058948 (1 µM) induces apoptosis in P39 and MUTZ-3 acute myeloid leukemia (AML) cells.2 It decreases the survival of P39 and MUTZ-3 cells but not a variety of other AML and non-AML cells, including ME-1, U937, HL-60, and K562 cells. KU-0058948 (5 nM) potentiates cytotoxicity induced by MS-275 (Item No. 13284) in patient-derived AML cells. It reduces survival of HCT116 cells deficient in phosphatase and tensin homolog (PTEN) but not those expressing wild-type PTEN or containing a PTEN construct (HCT116+/neo).3
