Uses and applications

What the substance is used for, by industry and function

Pharmacological actions

  • Estrogen Antagonists

Pharmacology

Triphenylethylene is the core chemical structure of a number of related anti-estrogen compounds. The triphenylethylene antiestrogens, which include idoxifene, toremifene, chlorotrianisene, raloxifene and tamoxifen, act at the level of the estrogen receptor, triggering inhibition or stimulation of estrogen-dependent gene transcription and cellular physiology. Triphenylethylenes were initially developed for the treatment of estrogen-dependent breast cancers. Selective estrogen receptor modulators (SERMs) such as raloxifene and tamoxifen represent triphenylethylene derivatives that affect transcriptional regulation through modulation of specific alpha and beta estrogen receptors that are differentially expressed in various normal and neoplastic tissues.
