Synthesis, antimicrobial evaluation and in silico studies of novel 3,4-disubstituted pyrrolidinesulfonamides

Keywords: pyrrolidinesulfonamides, synthesis, in silico studies, β-glucosidase, antimicrobial activity

Abstract

3,4-Disubstituted pyrrolidinesulfonamides were synthesized and screened for their antimicrobial activity. Title compounds were established as potent antibacterial and antifungal agents. Noteworthy antimicrobial activity was found for the title compounds against the tested microorganisms. They exhibit comparable results with standard drugs. Besides the in vitro antimicrobial activity, the synthesized compounds were evaluated for their in silico inhibitory activity on active site of β-glucosidase enzyme. In silico studies were done by GOLD docking method against β-glucosidase 3VKK (PDB Id). In silico studies were conducted to evaluate the ability of synthesized compounds to inhibit the β-glucosidase enzyme. The results revealed that 3,4-disubstitutedpyrrolidinesulfonamides are the potent β-glucosidase inhibitors by binding at the active site. A sensible inhibition against β-glucosidases was observed for the compound with 13,4-oxadizole ring has higher β-glucosidase inhibition activity than the other compounds. The free energy of binding and inhibition constant (Ki) of the docked compounds were evaluated and presented.
