Chemical Name: 9,10,11,12-Tetrahydro- 9,12-epoxy-1H-diindolo[1,2,3-fg:3',2',1'-kl]pyrrolo[3,4-i][1,6]benzodiazocine-1,3(2H)-dione
Biological ActivitySB 218078 is an inhibitor of checkpoint kinase 1 (Chk1) that displays selectivity over other protein kinases (IC50 values are 15, 250 and 1000 nM for Chk1, cdc2 and PKC respectively). Abrogates G2 cell cycle arrest caused by γ-irradiation and topoisomerase I inhibition. Potentiates cytotoxicity of DNA-damaging drugs, enhancing the efficacy of some chemotherapeutics.
