Synthesis and evaluation of novel 1,2,3-triazole-based acetylcholinesterase inhibitors with neuroprotective activity

Bioorg Med Chem Lett. 2016 Aug 15;26(16):3881-5. doi: 10.1016/j.bmcl.2016.07.017. Epub 2016 Jul 7.

Abstract

A series of new 1,2,3-triazole derivatives were synthesized and evaluated for anticholinesterase and neuroprotective activities. Some synthetic derivatives, especially compound 32, exhibited improved acetylcholinesterase (AChE) inhibitory activity by comparison with the hit 1, high selectivity toward AChE over butyrylcholinesterase (BuChE), and suitable in vitro neuroprotective effect against amyloid-β25-35 (Aβ25-35)-induced neurotoxicity in SH-SY5Y cells. Furthermore, these molecules have desired physicochemical properties in the range of CNS drugs and showed no cytotoxicity against two normal cells, including human keratinocytes HaCaT and murine fibroblasts NIH-3T3. The preliminary bioassay results and docking study indicated that compound 32 might be a promising lead compound with dual action for the treatment of Alzheimer's disease.
