简介
In this study, we synthesized nine novel hybrids derived from D-xylose, D-ribose, and D-galactose sugars connected by a methylene chain with lophine. The compounds were synthesized by a four-component reaction to afford the substituted imidazole moiety, followed by the displacement reaction between sugar derivatives with an appropriate N-alkylamino-lophine. All the compounds were found to be the potent and selective inhibitors of BuChE activity in mouse serum, with compound 9a (a D-galactose derivative) being the most potent inhibitor (IC50 = 0.17 μM). According to the molecular modeling results, all the compounds indicated that the lophine moiety existed at the bottom of the BuChE cavity and formed a T-stacking interaction with Trp231, a residue accessible exclusively in the BuChE cavity. Noteworthily, only one compound exhibited activity against AChE (8b; IC50 = 2.75 μM). Moreover, the in silico …
