Abstract: In the present work, new quinolone-2-thio-acetamide-propane hydrazide-benzimidazole derivatives 12a-o were assigned as potent anti-diabetic agents that targeting α-glucosidase and α-amylase as two important targets in treatment of type 2 diabetes. General scaffold of these compounds was designed based on the reported potent α-glucosidase and α-amylase inhibitors and derivation was performed in acetamide moiety. In vitro evaluation of the new compounds 12a-o demonstrated that most of the synthesized compounds were more potent than standard inhibitor acarbose against α-glucosidase while all these new compounds were more potent than acaerbose against α-amylase. The most potent compound against both studied enzymes was compound 12n that was a 4-fluorophenylacetamide derivative. This compound was 5 and 23.8 folds more potent than acarbose against α-glucosidase and α-amylase, respectively, and with excellent binding energies in comparison to acarbose attached to active sites of these enzymes. Molecular dynamics and pharmacokinetic studies of compound 12n was also performed.
