2-Methoxyestradiol

2-methoxy Estradiol (2-ME2) is a natural metabolite formed by CYP450-mediated hydroxylation followed by catechol-O-methyltransferase (COMT) methylation of estradiol. Administration of 2-hydroxy estradiol (2-HE2) to rats results in formation and clearance of 2-ME2 with t½ values of 7.9 and 24.9 minutes, respectively. 2-ME2 exhibits no affinity for estrogen receptors. 2-ME2 has achieved considerable attention as an anti-cancer agent acting as an angiogenesis inhibitor via the HIF-1alpha pathway. The levels of COMT and 2-ME2 are significantly lower in women with severe pre-eclampsia.Formal Name: 2-methoxy-estra-1,3,5(10)-triene-3,17beta-diol. CAS Number: 362-07-2.
