The central role of microtubules in cell division and mitosis makes them a particularly important target for anticancer agents. On our early publication, we found that a series of 2- (3′, 4′, 5′-trimethoxybenzoyl)-3-aminobenzo [b] thiophenes exhibited strong antiproliferative activity in the submicromolar range and significantly arrested cells in the G2– M phase of the cell cycle and induced apoptosis. In order to investigate the importance of ...
