Description: Acolbifene, also known as EM-652, or SCH-57068, is a selective estrogen receptor modulator (SERM). Acolbifene is currently being studied in the prevention of breast cancer in women at high risk of breast cancer. EM-652 (SCH 57068) and the prodrug EM-800 (SCH57050) which are the most potent of the known antiestrogens. EM-652 is the compound having the highest affinity for the estrogen receptor, including estradiol. It has higher affinity for the ER than ICI 182780, hydroxytamoxifen, raloxifene, droloxifene and hydroxytoremifene. EM-652 has the most potent inhibitory activity on both ER alpha and ER beta compared to any of the other antiestrogens tested. EM-652 was also the most potent inhibitor of the percentage of cycling cancer cells. ( J Steroid Biochem Mol Biol. 1999 Apr-Jun;69(1-6):51-84.)
