Abstract

Several arylthioindoles had excellent activity as inhibitors both of tubulin polymerization and of the growth of MCF-7 human breast carcinoma cells. Methyl 3-[(3,4,5-trimethoxyphenyl) thio]-5-methoxy-1H-indole-2-carboxylate (21), the most potent derivative, showed IC50 ) 2.0 microM, 1.6 times more active than colchicine and about as active as combretastatin A-4 (CSA4). Compound 21 inhibited the growth of the MCF-7 cells at IC50 ) 13 nanoM. Colchicine and CSA4 had 13 nanoM and 17 nanoM IC50 values, respectively, with these cells.
