Design and synthesis of tamoxifen derivatives as a selective estrogen receptor down-regulator.

Abstract:

:We designed and synthesized an estrogen receptor (ER) down-regulator (5), which is a derivative of tamoxifen with a long alkyl side chain. Compound 5 effectively reduced ER protein levels in MCF-7 cells and had an antagonistic effect.
