Isolated from Streptomyces sp., Antibiotic UCN-01 inhibits protein kinase C (PKC) and cyclin-dependent kinase 2 (CDK2) resulting in accumulation of cells in the G1 phase and induction of apoptosis. UCN-01 also enhances the cytotoxicity of other anti-cancer drugs, such as DNA-damaging agents and anti-metabolite drugs, through putative abrogation of G2 and/or S phase accumulation induced by these anti-cancer agents.
