Synthesis and Antimicrobial Activities of Novel Series of 3-(4-(2-substituted thiazol-4-yl)phenyl)-2-(4-methyl-2-substituted thiazol-5-yl)thiazolidin-4-one Derivatives

In the present investigation, a novel series of 3‐(4‐(2‐substituted thiazol‐4‐yl)phenyl)‐2‐(4‐methyl‐2‐substituted thiazol‐5‐yl)thiazolidin‐4‐one derivatives were synthesized by condensation of 2‐substituted‐4‐methylthiazole‐5‐carbaldehyde with 4‐(2‐substituted thiazol‐4‐yl)benzenamine followed by cyclo‐condensation with thioglycolic acid in toluene. All the newly synthesized compounds were characterized by spectral (IR, 1H NMR, 13C NMR, and Mass) methods. The title compounds were screened for quantitative antibacterial activity (minimal inhibitory concentration). All compounds 7a, 7b, 7c, 7d, 7e, 7f, 7g, 7h and 8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h show moderate to good antimicrobial activity, whereas compounds (7a, 7b, 7c, 7d, 7e, 7f, 7g, 7h) also show moderate antifungal activity.
