NCIt definition : An orally bioavailable estradiol metabolite with potential antineoplastic activity.
2-Methoxyestradiol inhibits angiogenesis by reducing endothelial cell proliferation
and inducing endothelial cell apoptosis. This agent also inhibits tumor cell growth
by binding to tubulin, resulting in antimitotic activity, and by inducing caspase
activation, resulting in cell cycle arrest in the G2 phase, DNA fragmentation, and
apoptosis. (NCI04);
Alternative definition : NCI-GLOSS: 2ME2. A drug derived from estrogen that belongs to the family of drugs
called angiogenesis inhibitors. It prevents the formation of new blood vessels that
tumors need in order to grow.;
