Chemical compound
D-15414 is anonsteroidal weakestrogen of the2-phenylindole group which was never marketed.[ 1] [ 2] It is the majormetabolite of theselective estrogen receptor modulator (SERM)zindoxifene (D-16726).[ 3] D-15414 has highaffinity for theestrogen receptor (ER) and inhibits the growth of ER-positiveMCF-7 breast cancer cells in vitro .[ 3] However, contradictorily, subsequent research found that the drug produced fullyestrogenic effectsin vitro similarly to but less actively thanestradiol ,with noantiestrogenic activity observed.[ 1] [ 2] The reason for the discrepancy between the findings is unclear, though may be due tomethodology .[ 2] The unexpected estrogenic activity of D-15414 may be responsible for the failure of zindoxifene inclinical trials as a treatment forbreast cancer .[ 1] [ 4]
