This experiment was designed to synthesize 18 kinds of polyhydroxybenzophenones by using Friedel-Crafts reaction, and to measure the inhibitory activity on α-glucosidase with p-nitrophenyl-β-D- galactopyranoside (PNPG) as a substrate. Here, acarbose (IC50a= a1674.75aaμmolaL-1) was used as the reference inhibitor. The results demonstrated that most of the target compounds had remarkable inhibitory activities on α-glucosidase. Among all these compounds, 2,4,4′,6-butahydroxydiphenylketone (11) was found to be the most potent α-glucosidase inhibitor with an IC50 value of 10.62aaμmolaL-1. In addition, we found these compounds were competitive inhibitors through the kinetic analysis. The results suggested that such compounds might be utilized for the development of new candidates for diabetes treatment. A series of polyhydroxybenzophenones was synthesized and evaluated as α-glucosidase inhibitors. Compound 11 was found to be the most potent inhibitor. Copyright
