Zindoxifene (D 16726 or 5-acetoxy-2-(4-acetoxyphenyl)-1-ethyl-3-methylindole), is an antiestrogenic phenylindole with a high affinity for the estrogen receptor. Zindoxifene exerts inhibiting activity against tumors of prostatic and mammary origins both in vitro and in vivo. It was in phase I/II study for the treatment of advanced breast cancer. Zindoxifene development has been discontinued.
