ABSTRACT


A small collection of 2-hydroxy-N-(5-methyl/nonsubstituted 4-oxo-2-substituted phenyl-1,3-thiazolidin-3-yl)-2-phenylacetamides (3-16) was synthesized from the cyclocondensation of 2-hydroxy-2-phenyl-N'-[(substitutedphenyl)methylene]acetohydrazides (2) and mercaptoethanoic acid or 2-mercaptopropanoic acid, characterized with spectral and elemental analysis. In order to explore their antimycobacterial potential, newly synthesized fourteen compounds were screened for their inhibitory activity against Mycobacterium tuberculosis strain H37Rv at 6.25 μg/mL with in-vitro primary tests. Compound 7 was found to provide the highest inhibition (98%) M. tuberculosis strain H37Rv, while most of the new derivatives showed different inhibition ratios. For the search of the putative targets which are considered as related to the antimycobacterial activity of these molecules, docking studies were performed. With molecular dynamic simulations, further possible interactions between ligands and the active site of the selected enzymes were investigated. Eventually, molecular modelling studies indicated that at least part of the mechanism of action of these compounds may be mediated by inhibition of MtInhA.
