Antimicrobial screening of N-[(2-substituted phenyl)-4-oxo-1,3-thiazolidine-3-Yl]isonicotinamides

Some new N-[(2-substituted phenyl)-4-oxo-1, 3-thiazolidine-3-yl]isonicotinamide derivatives (3a-e) have been synthesized by the reaction of N'-[(1E)-arylmethylene]isonicotinohydrazide (2a-e) with thioglycolicacid These compounds were characterized on the basis of elemental and spectral analysis. The title compounds were screened for their antimicrobial activity and found to exhibit a variable degree of activity.
