Curator's Comment: Description was created based on several sources, including http://www.ncbi.nlm.nih.gov/pubmed/1893497

TAT-59 (Miproxifene Phosphate) is a triphenylethylene analog of tamoxifen. TAT-59 is the phosphate ester prodrug of the practically insoluble parent drug DP-TAT-59. It is an antiestrogen developed in Japan for breast cancer. It is a potent antitumor agent for hormone-dependent tumors. Most of TAT-59 metabolites possessed remarkable binding affinity toward estrogenic receptors as well as fairly good antiuterotrophic activity.
