(重定向自Methoxyestradiol)

2-Methoxyestradiol (2ME2) is a natural metabolite of estradiol. As an experimental drug candidate, it is being developed under the tradename of Panzem. It prevents the formation of new blood vessels that tumors need in order to grow (angiogenesis), hence it is an angiogenesis inhibitor.
