Abstract

A series of isatin analogs containing a hydrophilic group, including a pyridine ring, ethylene glycol group, and a triazole ring, have been synthesized, and their inhibition potency for caspase-3 was measured both in vitro (i.e., recombinant enzyme) and in whole cells (HeLa cells). The analogs having a hydrophilic group, including 12, 13, 16, 38, and 40, have dramatically increased activity in vitro and in HeLa cells compared to the corresponding unsubstituted N-phenyl isatin analogs.
