生物活性
描述 Endoxifen Z-isomer hydrochloride, recognized as a pivotal Tamoxifen metabolite, plays a crucial role in delivering the anti-estrogenic effects of Tamoxifen in breast cancer cells that express estrogen receptor-alpha (ERα). It impedes hERG tail currents at 50 mV in a dose-responsive manner, with IC50 values established at 1.6 μM[1]. Furthermore, Endoxifen demonstrates greater potency in inhibiting estrogen target genes in the presence of ERβ. Notably, in patients treated with Tamoxifen exhibiting deficient CYP2D6 activity, low Endoxifen concentrations (20 to 40 nM) significantly reduce estrogen-induced cell proliferation rates when ERβ is expressed, contrasting with the higher concentrations required in the absence of ERβ[2].
