Design, synthesis, and α-glucosidase-inhibitory activity of phenoxy-biscoumarin–N-phenylacetamide hybrids
Thirteen new phenoxy-biscoumarin–N-phenylacetamide derivatives (7a–m) were designed based on a molecular hybridization approach as new α-glucosidase inhibitors. These compounds were synthesized with high yields and evaluated in vitro for their inhibitory activity against yeast α-glucosidase. The obtained results revealed that a significant proportion of the synthesized compounds showed considerable α-glucosidase-inhibitory activity in comparison to acarbose as a positive control. Representatively, 2-(4-(bis(4-hydroxy-2-oxo-2H-chromen-3-yl)methyl)phenoxy)-N-(4-bromophenyl)acetamide (7f), with IC50 = 41.73 ± 0.38 μM against α-glucosidase, was around 18 times more potent than acarbose (IC50 = 750.0 ± 10.0 μM). This compound was a competitive α-glucosidase inhibitor. Molecular modeling and dynamic simulation of these compounds confirmed the obtained results through in vitro experiments. Prediction of the druglikeness/ADME/toxicity of the compound 7f and comparison with the standard drug acarbose showed that the new compound 7f was probably better than the standard drug in terms of toxicity.
