Daidzein is an isoflavone compound derived from soybeans structurally classified as a phytoestrogen with structural similarity to endogenous estrogen It has been widely investigated for its potential in biomedical research particularly in oncology and cell biology studies Daidzein exhibits anticancer-related biological activity possibly via modulation of hormonal signaling pathways and interference with cell cycle progression as exemplified by inducing cell cycle arrest at the G1 phase in cultured mammalian cells Additionally it demonstrates antioxidant properties providing protective effects against oxidative stress-mediated cell injury such as hepatic cellular damage induced by chemical carcinogens Daidzein is thus employed in studies focused on hormone-dependent tumorigenesis cell-cycle regulation mechanisms and oxidative-stress-induced cellular responses
