The synthesis and biological assessment of novel multi-functionalized pyrrolidine-containing benzenesulfonamides were reported. These compounds showed antimicrobial, antifungal, CAs inhibition, AChE inhibition, and DNA-binding effects. The most potent CAs inhibitor was compound 3b, while compounds 6a and 6b showed remarkable AChE inhibition effects. Additionally, compounds 6a-6c had moderate antituberculosis effects. The study also included molecular docking studies to evaluate the interaction of selected compounds against enzymes (CAs and AChE).
The synthesis and biological assessment of novel multi-functionalized pyrrolidine-containing benzenesulfonamides were reported along with their antimicrobial, antifungal, CAs inhibition, and AChE inhibition as well as DNA-binding effects. The chemical structure of the compounds was elucidated by using FTIR, NMR, and HRMS. Compound 3b, which had Ki values of 17.61 +/- 3.58 nM (hCA I) and 5.14 +/- 0.61 nM (hCA II), was found the be the most potent CAs inhibitor. Compounds 6a and 6b showed remarkable AChE inhibition effects with Ki values 22.34 +/- 4.53 nM and 27.21 +/- 3.96 nM in comparison to tacrine. Compounds 6a-6c had moderate antituberculosis effect on M. tuberculosis with a MIC value of 15.62 mu g/ml. Compounds had weaker antifungal and antibacterial activity in the range of MIC 500-62.5 mu g/ml against standard bacterial and fungal strains. Besides these above, molecular docking studies were performed to examine and evaluate the interaction of the remarkable compounds (3b, 6a and 6b) against the current enzymes (CAs and AChE). Novel compounds gained interest in terms of enzyme inhibitory potencies. Therefore, the most potent enzyme inhibitors may be considered lead compounds to be modified for further research.Communicated by Ramaswamy H. Sarma
