RESUMEN

A series of novel 2-amino-3-cyano-6-(1H-indol-3-yl)-4-phenylpyridine derivatives were synthesized and their cytotoxic activity against A549, H460, HT-29 and SMMC-7721 cell lines was evaluated in vitro. Among them, ten compounds (10, 11, 14, 16, 17, 26, 27, 29, 30 and 31) displayed excellent anti-tumor activity against different cell lines. The most promising compound 27 showed strong anti-tumor activity against A549, H460, HT-29 and SMMC-7721 cell lines with IC(50) values of 22, 0.23, 0.65 and 0.77 nM, which were 2.6-, 83-, 1.1×10(3)- and 2.0×10(3)- fold more active than MX-58151 (IC(50) values of 0.058, 0.019, 0.70 and 1.53 μM), respectively.
