GtoPdb Ligand ID: 10204

Synonyms: Z-norendoxifen
Compound class: Synthetic organic
Comment: Norendoxifen is an active metabolite of tamoxifen. In addition to acting as an estrogen receptor modulator, norendoxifen also inhibits aromatase enzyme activity (i.e. inhibits estrogen biosynthesis) [1-2]. We show the Z isomer here as it is more potent in terms of ER modulation and in vivo activity compared to the E isomer.
