Products resulting by free radical attack on aqueous genistein

Genistein (GEN) is a phytoestrogen of the isoflavonoid group, which, in addition to its antitumor properties of breast cancer, also shows various distinguished biological effects. Products resulting from GEN by free radicals reactions in aqueous media were analyzed. Their yields are studied as a function of radical concentration (absorbed radiation dose) in neutral solution. The knowledge of GEN-degradation products is of special interest, since they can initiate biological side effects.
