Development of new donepezil analogs: synthesis, biological screening and in silico study rational

Abstract Fifteen new benzothiophene-based compounds were designed, synthesized, and evaluated as potential anti-Alzheimer agents. Most of the synthesized exhibited remarkable AChE inhibitory activity effectively inhibited self-mediated ?-amyloid protein in vitro. Compound 3g (IC 50 = 72.488 ± 3.69 ?M) showed a significant effect exceeding that donepezil 87.414 4.46 ?M). Furthermore, compound 3j 0.498 0.02 best comparable to 0.404 0.03 The vivo evaluation promising ( ) confirmed memory improvement scopolamine-induced impairment model mice. molecular docking simulation Torpedo californica- Tc AChE) active site good agreement with obtained screening results. silico ADMET other physicochemical parameters also reported.
