MedKoo CAT#: 201830

CAS#: 362-07-2

Description: 2-methoxyestradiol, also known as 2-ME, is 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.

Additional Information

2-Methoxyestradiol (2ME2) is a drug that prevents the formation of new blood vessels that tumors need in order to grow (angiogenesis). It is derived from estrogen, although it binds poorly to known estrogen receptors, and belongs to the family of drugs called angiogenesis inhibitors. It has undergone Phase 1 clinical trials against breast cancers. Preclinical models also suggest that 2ME2 could also be effective against inflammatory diseases such as rheumatoid arthritis. The CAS name for 2ME2 is (17 beta)-2-methoxyestra-1,3,5(10)-triene-3,17-diol. It also acts as a vasodilator. Several studies have been conducted showing 2ME2 is a microtubule-inhibitor and effective against prostate cancer in rodents. see http://en.wikipedia.org/wiki/2-methoxyestradiol .
