Norendoxifen, also known as 4-hydroxy-N,N-didesmethyltamoxifen, is a nonsteroidal aromatase inhibitor (AI) of the triphenylethylene group that was never marketed.[1] It is an active metabolite of the selective estrogen receptor modulator (SERM) tamoxifen.[1] Unlike tamoxifen, norendoxifen is not a SERM, and instead has been found to act as a potent and selective competitive inhibitor of aromatase (Ki = 35 nM).[1] Drugs with dual SERM and AI activity, such as 4'-hydroxynorendoxifen, have been developed from norendoxifen, and may have therapeutic potential as antiestrogens in the treatment of estrogen receptor-positive breast cancer.[2]
