Abstract
In this study, a novel series of 4-thiazolidinone derivatives (1-17) was synthesized and evaluated for its in vitro antimicrobial and anticancer potentials. N-(2-(5-(4-nitrobenzylidene)-2-(4-chlorophenyl)-4-oxothia- zolidin-3-ylamino)-2-oxoethyl) benzamide (7, pMICam = 1.86 mu M/mL) was found to be the most active antimi- crobial agent. The anticancer study results demonstrated that N-(2-(5-(4-hydroxybenzylidene)-2-(4- methoxyphenyl)-4-oxothiazolidin-3-ylamino)-2-oxoethyl) benzamide (10, IC50 = 18.59 mu M) was the most active anticancer agent. QSAR studies indicated the importance of topological parameter, Kier's alpha third order shape index (k alpha(3)) as well as electronic parameters, cosmic total energy (cos E) and energy of highest occupied molecular orbital (HOMO) in describing the antimicrobial activity of synthesized compounds.
