Abstract

A novel series of 1,6-bis-triazole-benzyl-α-glucoside derivatives (7a-7ee) were designed, synthesized and evaluated for inhibitory activity against α-glucosidase. Most of the synthesized compounds exhibited good activity with IC<sub>50</sub> ranging from 3.73 µM to 53.34 µM and are more potent than the standard drug acarbose (IC<sub>50</sub> = 146.25 ± 0.40 µM). SARs study showed the ester and menthol moiety play an important role in the inhibitory activity. The molecular docking model of the potent compounds 7f, 7z, 7cc and 7dd showed good binding energy and interacts well with amino acid residues around the active site of the enzyme, which confirmed the in vitro activity results.
