Synthesis and in-vitro activity of some new class of thiazolidinone and their arylidene derivatives

Abstract

In an attempt to find a new class of anti microbial agents, a series of thiazolidinone and their 5-arylidene derivatives containing 4-(4-methyl benzamido)-benzoyl moiety were synthesized via the reaction of benzocaine with appropriate chemical reagents. These compounds were screened for their antibacterial activity against Gram-positive bacteria (Bacillus subtilis and Bacillus thuringiensis), Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa) and antifungal activity against Botrytis fabae, Fusarium oxysporan and Candida albicans. On the other hand the synthesized compounds were also screened for their anti tubercular activity. IR, 1H NMR, 13C NMR and MS spectral analyses established the structures of the newly synthesized compounds. The results revealed that some of these compounds have shown promising antimicrobial and anti tubercular activity in comparison with standard drugs. Copyright © 2005 KCSNET.
