Biochem/physiol Actions

The carcinogen hexestrol is a nonsteroidal synthetic estrogen. Metabolic activation of hexestrol to its quinone, which reacts with DNA to form analogous depurinating adducts, may be a primary critical event leading to oncogenic mutations and cancer initiation.

General description

Hexestrol is a synthetic nonsteroidal estrogen, which can be used in human medicine as well as a growth promoter in cattle.
