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