    Novel coumarin-triazole-coumarin dyads were synthesized and characterized, and their alpha-glycosidase inhibitory activities were evaluated spectrophotometrically. Compound 4e exhibited the most pronounced inhibitory effect, with an IC50value of 38.98 +/- 0.77 mu M. The IC50 values for 4d and 4a were 93.55 +/- 1.70 mu M and 95.04 +/- 3.55 mu M, respectively. The Lineweaver-Burk plot showed that 4e inhibited alpha-glycosidase in a mixed type. In addition, the Ki value obtained from the Dixon plot was 19.95 +/- 0.15 mu M for alpha-glycosidase.
