Metabolite Identification
Common Name Estrone-2,3-quinone
Description Estrogen 2,3- and 3,4-quinones are reactive species toward nucleophiles and Michael acceptors. As such, they can bind to DNA and induce cellular damages.Tumors may arise in cells covalently damaged by the free radicals or by the quinones and stimulated to proliferate by hormone receptor-mediated. processes. This hypothesis is supported by the correlation between quinone formation, 8-hydroxylation of guanine bases of DNA and tumor incidence of 4- versus 2-hydroxylated estrogen metabolites. Moreover, estrone-3,4-quinone, but not. estrone-2,3-quinone, induced liver tumors in mice.
