Synthesis of New Hispolon Derived Pyrazole Sulfonamides for Possible Antitubercular and Antimicrobial Agents

Abstract

Abstract. A series of 10 new hispolonpyrazole sulfonamides were designed and synthesized using hispolons and 4-sulfonamide phenylhydrazine hydrochloride with better yields. The synthesized pyrazole sulfonamides were screened for anti-TB, anti-bacterial, and anti-fungal activities to compare the role sulfonamide moiety. Among them, 3a and 3b showed selective potent anti-tubercular nature (MIC 6.25µg/mL). Further, the antimicrobial studies of the compounds showed only compound 3b with a good inhibition zone on Staphylococcus aureus among other bacteria and fungi studied.   Resumen.Se prepararon 10 nuevas hispolon-pirazol-suklfonamidas con buenos rendimientos haciendo reaccionar hipolonas y el clorhidrato de 4-sulfonamidil-fenílhidrazina. Los productos obtenidos se probaron contra cepas de hongos y bacterias con especial interés en la tuberculosis, encontrando algunos derivados con actividades del orden de MIC 6.25µg/mL.
