Synthesis, Characterization and Antimicrobial Evaluation of some 1,2,4-Triazolo-5-Thione Derivatives

Due to this increasing predicament of antibiotic confrontation, the lot of distinct antibiotics available is dwindling and there are only smatterings of new antibiotics in the drug development channel. Therefore, an intense necessitate for new antimicrobial drugs. In current study, substituted 1,2,4-triazolo-5-thione derivatives were synthesized from substituted aromatic aldehydes, succinic acids and the structure of synthesized compounds were established by physicochemical (Melting Point, Rf value) and spectral analysis (IR, NMR & Mass). The title compounds were then evaluated for their antimicrobial activity against ciprofloxacin as a standard drug using agar plate method. Among all synthesized derivatives A5 and A6 found were found to possess very promising antimicrobial activity. Keywords: 1,2,4-triazolo-5-thione, anti-microbial, antibiotic, thione, Ciprofloxacin.
