Synthesis, Characterization and Biological Evaluation of some Newer 5-[6-Chloro/Fluor/Nitro-2-(p-Chloro/Fluoro/Methyl Phenyl)-Quinolin-4-yl]-1,3,4-Oxadiazole-2-Thiols

Abstract

Recent study shows that quinolines represent one of the most active classes of compounds possesses wide spectrum biodynamic activities and use as potent therapeutic agents. In present research work, 5-[6-chloro/fluoro/nitro-2-(p-chloro/fluoro/methyl phenyl)-quinolin-4-yl]-1,3,4-oxadiazole-2-thiols have been synthesized by condensation of substituted quinoline-4-carbohydrazides and mixture of carbon disulphide and potassium hydroxide. All of these compounds were screened for their in vitro anti microbial assay against gram (+ve), gram (-ve) bacteria and fungi activity compared with standard drugs viz., Ampicilin, Chloramphenicol, Ciprofloxacin, Norfloxacin, Griseofulvin and Nystatin at different concentrations.
