Pharmacophore optimization of imidazole chalcones to modulate microtubule dynamics.

ABSTRACT: We recently reported a new class of imidazole-based chalcones as potential antimitotic agents. In view of their promising cytotoxic activity, a comprehensive structure-activity relationship (SAR) of these compounds was undertaken focusing on four major structural variations: the length of the molecule, the Michael acceptor character, the nature and substitution pattern of ring B, and the nature of the amide functionality tethering ring B. These second-generation analogs (IBCs) demonstrated a superior bioactivity profile than the previously reported imidazole chalcones (referred to as IPEs). The analog IBC-2 with one less methylene group (nor series) and para-fluoro substituted ring B demonstrated the best cytotoxicity profile among the library of compounds. A computational analysis of the
