Broparestrol (INN ) (brand names Acnestrol, Longestrol; former developmental code name LN-107), also known as α-bromo-α,β-diphenyl-β-p-ethylphenylethylene (BDPE), is a synthetic, nonsteroidal selective estrogen receptor modulator (SERM) of the triphenylethylene group[1] that has been used in Europe as a dermatological agent and for the treatment of breast cancer.[2][3][4][5][6] The drug is described as slightly estrogenic[7] and potently antiestrogenic,[8][9] and inhibits mammary gland development and suppresses prolactin levels in animals.[10] It is structurally related to clomifene and diethylstilbestrol.[6][10] Broparestrol is a mixture of E- and Z- isomers (LN-1643 and LN-2299, respectively), both of which are active, and are similarly antiestrogenic but, unlike broparestrol, were never marketed.[2]
