Daidzin is a potent, selective inhibitor of human mitochondrial aldehyde dehydrogenase with a Ki of 40 nM, and uncompetitively with respect to the coenzyme NAD+. [1]
Daidzin has preventive effect on bone loss in ovariectomized rats appears to be due to suppression of bone turnover. [2]
Daidzin in the rhizome of Pueraria lobata are prodrugs, which has antiallergic and antithrombotic activities, can inhibit ADP- and collagen-induced platelet aggregation, produced by intestinal microflora.[3]
Daidzin and puerarin can induce a conformational change of beta-CD, which is compressed in one direction and stretched in the other. [4]
