Daidzin is an isoflavone. Like many isoflavones, daidzin exhibits antioxidant properties, helping to neutralize free radicals and reduce oxidative stress. Daidzin is a potent inhibitor of human ALDH2 (mitochondrial aldehyde dehydrogenase 2) with an IC50 of 80 nM. This chemical is the glucoside of the isoflavone daidzein (sc-24001) found in soy bean meal (Soja hispada). Daidzein can be liberated from daidzin through hydrolysis. Daidzin has also been shown to demonstrate chemopreventive activities by inhibiting the bioactivation of carcinogenic arylamines.
