Genistin and daidzin are among the major isoflavonoids in soybeans and soy products,
genistin has antioxidant activity and anticarcinogenic properties, can inhibit UV light-induced plasmid DNA damage and cell growth in human melanoma cells.[1]
Genistein and genistin inhibit cell proliferation by disrupting the cell cycle, which is strongly associated with the arrest induction of either G1 or G2/M phase and may induce apoptosis, speculates that both genistein and genistin may prove useful as anticancer drugs and that the combination of genistein and genistin may have further anticancer activity.[2]
Dietary genistin can stimulate growth of estrogen-dependent breast cancer tumors similar to that observed with genistein.[3]
Genistin and daidzin have preventive effects on bone loss in ovariectomized rats fed a calcium-deficient diet.[4]
