Novel substituted indolocarbazoles were synthesized, and their kinase inhibitory capability was evaluated in vitro. 6-Substituted indolocarbazoles 4 were found to be potent and selective D1/CDK4 inhibitors. 4d and 4h exhibited potent and ATP-competitive D1/CDK4 activities with IC50 values of 76 and 42 nM, respectively. Both compounds had high selectivity against the other kinases. These D1/CDK4 inhibitors inhibited tumor cell growth, arrested tumor cells at the G1 phase, and inhibited pRb phosphorylation.

A series of fluoroindolocarbazoles were studied with respect to their topoisomeraseIactivity, cytotoxicity, selectivity, and in vivo antitumoractivity. Emerging from this series was BMS-251873, a potential clinical candidate possessing a robust pharmacological profile including curativeantitumoractivityagainstprostatecarcinoma.
