NNC 45-0095

NC 45-0095 is a synthetic nonsteroidal selective estrogen receptor modulator (SERM) which was under development by Novo Nordisk for the treatment of postmenopausal osteoporosis but was never marketed.[1][2][3][4][5] It is a partial agonist of the estrogen receptor (IC50 (for binding inhibition) = 9.5 nM; EC50 = 13 nM) with mixed estrogenic and antiestrogenic activity, and shows full estrogenic activity in bone and uterus (Emax (relative to moxestrol, in Ishikawa endometrial cancer cell line) = 105%).[1][4] The compound is a pyrroloindolizine derivative.[1][2] Its development was discontinued by 2003.[5]
