Background: Diseases caused by microbial infections are very common worldwide. Although the search of innovative antimicrobial agents is the current focus for the researchers, the treatment of infectious diseases remains an important public health issue and a challenging problem in front of medicinal chemist.

Methods: A series of 2-(4-hydroxyphenyl)-3-(4-(4-nitrophenyl) thiazol-2-yl)thiazolidin-4-one derivatives (T1-T10) was designed and synthesized. All the titled compounds were evaluated for their antimicrobial potential. Antimicrobial activity was performed by tube dilution methods against Gram negative Escherichia coli MTCC 443 (E. Coli), Gram positive bacteria: Staphylococcus aureus MTCC 3160 (S. aureus) and Bacillus subtilis MTCC 441 (B. Subtilis), and fungal strains: Aspergillus niger MTCC 281 (A. niger) and Candida albicans MTCC 227 (C. albicans).

Results: Among the synthesized derivatives, compounds 2, 4 and 10 were found to be most active antimicrobial agents.

Conclusion: In conclusion, a series of 2-(phenyl)-3-(4-(phenyl)thiazol-2-yl)thiazolidin-4-ones have been designed and synthesized. All the titled compounds were evaluated for their in vitro antimicrobial activity against five representative microorganisms. The results of antimicrobial study indicated that the presence of nitro and chloro groups in aromatic ring improved antibacterial activity, whereas the presence of hydroxy group improved antifungal activity of substituted 4-thiazolidinone derivatives.
