coumarin-isatin derivatives. Furthermore, enzyme kinetic studies showed that compound 5p is a non-competitive inhibitor with a Ki of 2.14 mum. Molecular docking analysis revealed the existence of hydrophobic and hydrogen interactions between compound 5p and the active site of alpha-glucosidase. Our results indicate that coumarin-isatin derivatives as a new class of alpha-glucosidase inhibitors.

biologically active component. The reported MptpB inhibitors show excellent selectivity against a selected panel of protein tyrosinephosphatases, including MptpA (M. tuberculosis protein tyrosinephosphatase A), PTP1B (protein tyrosinephosphatase 1B), SHP-2 (Src homology 2 domain-containing protein tyrosinephosphatase), PTPN2, h-PTPβ (human protein tyrosinephosphatase β), and VHR (Vaccinia virus VH1-related
