Synthesis, characterization, biological evaluation, and kinetic study of indole base sulfonamide derivatives as acetylcholinesterase inhibitors in search of potent anti-Alzheimer agent

Alzheimer is a prolonged neurodegenerative disease which degenerate the brain cells and particularly affects the person ability to function independently. Despite of dynamic research, there is no proper treatment but can limit their persistent effect in early stages. In search of more potent drug for Alzheimer treatment, we have synthesized indole-based sulfonamide derivatives (1-17). All analogs were screened to find out lead candidate against acetylcholinesterase enzyme under positive control of donepezil as standard drug. Herein this study, analogs 1-4, 6-9, and 13-15 showed potent inhibition while kinetic studies further confirmed their mode of inhibition. All the synthesized analogs were characterized through HR-EI-MS, H-1 NMR and C-13 NMR spectroscopic techniques. (C) 2021 The Author(s). Published by Elsevier B.V. on behalf of King Saud University.

Automated summary

Alzheimer's disease is a neurodegenerative disease that currently lacks effective treatment, but researchers are exploring more potent drugs for treatment, with indole-based sulfonamide derivatives showing potential inhibitory effects.
