A series of indole-2-carboxylic acid benzylidene-hydrazides has been identified as a new class of potent apoptosis inducers through a novel cell-based caspase HTS assay. The screening hit, 5-chloro-3-methyl-indole-2-carboxylic acid (4-nitrobenzylidene)-hydrazide (3a), was found to arrest T47D cells in G(2)/M and to induce apoptosis as measured by the flow cytometric analysis assay. A SAR study was carried out by modification of the substitutions on the indole and benzene rings. Substitution at the 3-position of the indole ring was found to be important for apoptotic activity. A 20-fold increase of apoptotic activity was achieved from screening hit 3a to 5-methyl-3-phenyl-indole-2-carboxylic acid (4-methylbenzylidene)-hydrazide (9a) and 5-chloro-3-phenyl-indole-2-carboxylic acid (4-nitrobenzylidene)-hydrazide (9b), with EC(50) value of 0.1microM in the caspase activation assay in T47D breast cancer cells. Compound 9b also was found to be highly active in a standard growth inhibition assay with a GI(50) value of 0.9microM in T47D cells. Compound 3a and its analogs were found to inhibit tubulin polymerization, which is the most probable primary mechanism of action of these compounds.
