Synthesis of Novel Analogues of Marine Indole Alkaloids: Mono(indolyl)-4-trifluoromethylpyridines and Bis(indolyl)-4-trifluoromethylpyridines as Potential Anticancer Agents
摘要:
Mono(indolyl)-4-trifluoromethylpyridines and bis(indolyl)-4-trifluoromethylpyridines were synthesized using Suzuki cross-coupling reaction between 2-chloro-4-trifluoromethylpyridine 9, 2,6-dichloro-4-trifluoromethylpyridine 6 or 2,6-dichloro-3-cyano-4-trifluoromethylpyridine 23 and N-tosyl-3-indolylboronic acid 10. They were evaluated for cytotoxic activity against P388 and A-549 cells with IC50 values. 4-Trifluoromethyl-2,6-bis[3'-(N-tosyl-6'-methoxylindolyl)]pyridine 18 was identified as the most potent in this series.

Optically active alpha -indolyl N-substituted glycines were synthesized by reaction of an indolyl boronic acid with glyoxylic acid using chiral methylbenzylamine as the chiral auxiliary with high diastereoselectivity. The absolute configuration of the product was determined by a single-crystal X-ray analysis. (C) 2001 Elsevier Science Ltd. All rights reserved.

A series of novel monoindolyl-4-trifluoromethylpyridines and bisindolyl-4-trifluoromethylpyridines was designed and synthesized as potential antitumor agents. They were evaluated for preliminary cytotoxic activity against P388 and A-549 cells with IC50 values. 4-Trifluoromethyl-2,6-bis[3'-(N-tosyl-6'-methoxyl-indolyl)] pyridine was identified as the most potent in this series.
