11β-Methoxyestradiol

Chemical compound

11β-Methoxyestradiol (11β-MeOE2; developmental code name RU-2504) is a synthetic steroidal estrogen which was never marketed.[1][2][3] It has about 86% of the relative binding affinity of estradiol for the estrogen receptor.[1][2] 11β-MeOE2 is structurally related to moxestrol (11β-methoxy-17α-ethynylestradiol).[3][2] 11β-MeOE2 and moxestrol are substantially more potent than their non-methoxylated analogues (estradiol and ethinylestradiol, respectively) in mice.[3]
