D-15414 is a nonsteroidal weak estrogen of the 2-phenylindole group which was never marketed.[1][2] It is the major metabolite of the selective estrogen receptor modulator (SERM) zindoxifene (D-16726).[3] D-15414 has high affinity for the estrogen receptor (ER) and inhibits the growth of ER-positive MCF-7 breast cancer cells in vitro.[3] However, contradictorily, subsequent research found that the drug produced fully estrogenic effects in vitro similarly to but less actively than estradiol, with no antiestrogenic activity observed.[1][2] The reason for the discrepancy between the findings is unclear, though may be due to methodology.[2] The unexpected estrogenic activity of D-15414 may be responsible for the failure of zindoxifene in clinical trials as a treatment for breast cancer.[1][4]
