A series of 1,2,4-triazine-coumarins were prepared by a one-pot, three-component condensation of 1,2-diarylethane-1,2-diones, thiosemicarbazide and 2-coumaryloxy-methyloxiranes using K2CO3 as a catalyst in aqueous medium. This three-component reaction offers several advantages such as simple procedure, environmentally friendly and high yields. The resulting products were characterized by H-1 NMR, C-13 NMR, HRMS and melting points. Furthermore, all newly synthesized compounds were evaluated for their a-glucosidase inhibitory activity. As a result, the majority of the screened compounds displayed potent inhibitory activity with IC50 values in the range of 32.57+/-0.21 to 148.77+/-3.23 mu M, when compared to the standard acarbose (IC50 = 876.14+/-2.46 mu M)
