In present study, the novel thiazolidinone derivatives were designed and synthesized. The formation of the target compounds was confirmed by the elemental analyses, FT-IR, mass spectroscopy and 1H NMR spectroscopy. These derivatives were subjected to antibacterial and antioxidant activities. The antibacterial results revealed that these derivatives were selectively active against Gram-negative Pseudomonas aeruginosa bacteria. Also, these derivatives displayed a good DPPH radical scavenging effect. Drosophila melanogaster flies were used for evaluating the toxic impact of novel thiazolidinone derivatives.
