Abstract

Rebeccamycin derivative 1 bearing a sugar moiety linked to both indole nitrogens and an amino substituent on the carbohydrate unit was synthesized in three steps from the bacterial metabolite. This compound was found to be a highly potent checkpoint kinase 1 inhibitor with an IC(50) value of 2.8nM.
