Description

CAS: 486-66-8 | C15H10O4 | 254.241 g/mol

4',7-Dihydroxyisoflavone is a phytoestrogen that is suggested to play a role in preventing hormone-induced cancers. It 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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
