Acetanilide was cyclized via Vilsmeier-Haack reagent to give 2- chloro -3- formyl quinoline. The aldehydic group was protected to prevent the preferential attack of nitrogen nucleophiles. The protection of aldehydic group in the present system was achieved with ethylene glycol to afford dioxolan derivative. Dioxolan derivative treated with nitro substituted phenyl hydrazine in alcoholic solution followed by deprotection of aldehydic group afforded the 2-(2-(2- nitrophenyl) hydrazinyl) quinoline-3-carbaldehyde and 2-(2-(2, 4-dinitrophenyl) hydrazinyl) quinoline-3- carbaldehyde. The synthesized derivatives were screened for antimicrobial activity.Keywords

A novel 5(4-(4-substituted)Aminobenzylidine)thiazolidine-2,4-dione derivatives were synthesized and characterized by IR and H-NMR spectral analysis. Antibacterial and antifungal activities of the compounds were assessed by in vitro growth inhibitory activity against Escherichia coli, Staphylococcus aureus, Asperigillus niger, Candida albicans by using the disc diffusion method. Most of all compounds exhibited significant antibacterial activity against Staphylococcus aureus and Escherichia coli, while weak antifungal activity against Asperigillus niger and Candida albicans.
