Estradiol mustard, also known as chlorphenacyl estradiol diester, as well as estradiol 3,17β-bis(4-(bis(2-chloroethyl)amino)phenyl)acetate, is a synthetic, steroidal estrogen and cytostatic antineoplastic agent and a chlorphenacyl nitrogen mustard-coupled estrogen ester that was never marketed.[1] It is selectively distributed into estrogen receptor (ER)-positive tissues such as ER-expressing tumors like those seen in breast and prostate cancers.[2] For this reason, estradiol mustard and other cytostatic-linked estrogens like estramustine phosphate have reduced toxicity relative to non-linked nitrogen mustard cytostatic antineoplastic agents.[2] However, they may stimulate breast tumor growth due to their inherent estrogenic activity and are said to be devoid of major therapeutic efficacy in breast cancer,[3] although estramustine phosphate has been approved for and is used (almost exclusively) in the treatment of prostate cancer.[4]
