Zindoxifene (INN; former developmental code names D-16726, NSC-341952) is a nonsteroidal selective estrogen receptor modulator (SERM) that was under development in the 1980s and early 1990s for the treatment of breast cancer but was not marketed.[1] It showed estrogenic-like activity in preclinical studies and failed to demonstrate effectiveness as a treatment for breast cancer in clinical trials.[2][3] Zindoxifene was the lead compound of the distinct 2-phenylindole class of SERMs,[4][5] and the marketed SERM bazedoxifene was derived from the major active metabolite of zindoxifene, D-15414.[2][3] Zindoxifene was first described in 1984.[1]
