General description

A cell-permeable, ATP-competitive, and reversible indolocarbazole derivative that acts as a potent and selective inhibitor of checkpoint kinase (Chk1) in vitro. It inhibits Chk1 phosphorylation of cdc25C with an IC50 of 15 nM. However, SB-218078 is a much weaker inhibitor of Cdc2 (IC50 = 250 nM) and PKC (IC50 = 1 µM).

A cell-permeable, ATP competitive, and reversible indolocarbazole derivative that acts as a potent inhibitor of checkpoint kinase (Chk1) in vitro (Ki = 15 nM). Binds to the ATP-binding pocket of Chk1, producing only slight changes in the protein conformation. Also inhibits the activity of CDK1 (Ki = 23 nM), CDK2 (Ki = 5.6 nM), and CDK4 (Ki = 16 nM). Inhibits Chk1 phosphorylation of Cdc25C (IC50 = 15 nM).
