General description

Daidzein is an isoflavone present in soy. It regulates oxidative stress, angiogenesis, cell growth and apoptosis. Daidzein has antioxidant, antiestrogenic and antiatherogenic properties. It provides protection against osteoporosis.

Application

Daidzein has been used:
  • as a control to evaluate fertility in rats
  • to study its effects on ovarian cancer
  • to simulate in vitro antioxidant activity

Biochem/physiol Actions

Soy isoflavone daidzein protects against oxidative damage in liver cells induced by 7,12-dimethylbenz[a]anthracene (DMBA). Catalase and superoxide dismutase activity, down-regulated by DMBA, was restored by daidzein.
Daidzein is a phytoestrogen that is suggested to play a role in preventing hormone-induced cancers. Arrests cell cycle at G1 in Swiss 3T3 cells.

Packaged under Argon.

Epidemiological studies suggest a lowered risk of hormone-dependent cancers among vegetarians, but the basis for this association remains unclear. Vegetables and fruits contain certain compounds which can be converted to biologically active hormone-like substances, such as lignans and isoflavones, by
