Triphenylethylene (TPE) is a simple aromatic hydrocarbon that possesses weak estrogenic activity.[1][2] Its estrogenic effects were discovered in 1937.[3] TPE was derived from structural modification of the more potent estrogen diethylstilbestrol, which is a member of the stilbestrol group of nonsteroidal estrogens.[4]

TPE is the parent compound of a group of nonsteroidal estrogen receptor ligands.[1][2][5] It includes the estrogens chlorotrianisene, estrobin (DBE), triphenylbromoethylene, triphenylchloroethylene, triphenyliodoethylene, triphenylmethylethylene; the selective estrogen receptor modulators (SERMs) afimoxifene, brilanestrant, broparestrol, clomifene, clomifenoxide, droloxifene, endoxifen, etacstil, fispemifene, idoxifene, miproxifene, miproxifene phosphate, nafoxidine, ospemifene, panomifene, and toremifene. The antiestrogen ethamoxytriphetol (MER-25) is also closely related, but is technically not a derivative of TPE and is instead a triphenylethanol derivative. The tamoxifen metabolite and aromatase inhibitor norendoxifen is also a TPE derivative. In addition to their estrogenic activity, various TPE derivatives like tamoxifen and clomifene have been found to act as protein kinase C inhibitors.[6]
