591-598A series of 4-thiazolidinone derivatives incorporating Mannich base of 3-(3-nitrophenyl)sydnone have been
synthesized by conventional routes and evaluated for their antimicrobial activities against E. coli, P. aerugenosa, S. aureus,
S. pyogenus, C. albicans, A. niger and A. clavatus. Most of the compounds show moderate to very good biological activity.
The structures of synthesized compounds 7a-j have been elucidated by C, H, and N analysis, FT-IR, 1H and 13C NMR and
mass spectrometry
