Desmethylchlorotrianisene (DMCTA) is a nonsteroidal estrogen which is thought to be the major active metabolite of chlorotrianisene (CTA; TACE). [1] [2] It is a 1:1 mixture of cis and trans isomers. [1] [2] DMCTA is produced from CTA via mono-O- demethylation catalyzed by cytochrome P450 enzymes in the liver. [1] [2] CTA is thought to act as a long-lasting prodrug of DMCTA. [1]
