General description

A cell-permeable Staurosporine (Cat. No. 569397) derived anticancer agent that reversibly and ATP-competitively inhibits several protein kinases (IC50 = 29 nM, 34 nM, 30 nM, 590 nM and 530 nM for PKCα, PKCβ, PKCγ, PKCδ and PKCε; IC50 = 7 nM, 27 nM, 50 nM, 50 nM, 150 nM and 1.04 M for Chk1, Cdc25C-associated protein kinase 1, Cdk1, PAK4, Cdk5/p25 and Chk2; IC50 = 33 nM, 50 nM, 95 nM, 500 nM, 500 nM and 1.0 M for PDK1, lck, MAPKAP kinase-2, Akt, GSK-3β and PKA, respectively). At higher concentrations (>15 M), affects the activities of Src, PIM-1, CKII, DNA-PK, ErK1, ILK-1 and MAPKK1). Reported to suppress thymidylate synthase expression, induce apoptosis with caspase activation, and sensitize tumor cells to a range of DNA-damaging agents.

Polo-like kinase 1 (PLK1) is a master kinase that regulates cell cycle progression. How its enzymatic activity is regulated in response to DNA damage is not fully understood. We show that PLK1 is enriched at double strand breaks (DSBs) within
