Abstract

A new series of 2-substituted quinazolin-4(3H)-one derivatives including coumarin nucleus has been synthesized and screened for their lipase and a-glucosidase inhibition properties. Among the synthesized compounds, N'-{2-[2-(3,4-dichlorobenzyl)-4-oxoquinazolin-3(4H)-yl]acetyl}-2-oxo-2H-chromene-3-carbohydrazide and N'-{2-[2-(4-bromobenzyl)-4-oxoquinazolin-3(4H)-yl] acetyl}-2-oxo-2H-chromene-3-carbohydrazide showed the best inhibitory effect against a-glucosidase with IC50 values of 6.11 +/- 0.40 and 7.34 +/- 0.37 mu M, respectively. These compounds also showed strong anti-lipase activity (IC50 3.52 +/- 0.49 and 2.85 +/- 0.27 mu M, respectively).
