The first synthesis of the tamoxifen metabolite norendoxifen is reported. This included syntheses of (E)-norendoxifen, (Z)-norendoxifen, and (E,Z)-norendoxifen isomers. (Z)-Norendoxifen displayed affinity for aromatase (Ki 442 nM), estrogen receptor-α (EC50 17 nM), and estrogen receptor-β (EC50 27.5 nM), while the corresponding values for (E)-norendoxifen were aromatase (Ki 48 nM), estrogen receptor-α
报道了他莫昔芬代谢物去甲内酯的首次合成。这包括 ( E )-去甲甲氧苄啶、( Z )-去甲甲氧苄啶和 ( E,Z )-去甲甲氧苄啶异构体的合成。( Z )-去甲氧苯丙胺显示出对芳香酶 ( K i 442 nM)、雌激素受体-α (EC 50 17 nM) 和雌激素受体-β (EC 50 27.5 nM) 的亲和力,而 ( E )-去甲氧灵的相应值是芳香酶 ( K i 48 nM)、雌激素受体-α (EC 50 58.7 nM) 和雌激素受体-β (EC 5078.5 纳米)。使用 ( E )-norendoxifen 对芳香酶进行对接和能量最小化研究,结果为基于结构的药物设计提供了基础。在小鼠中测定了 ( E , Z )-norendoxifen的口服药代动力学参数,发现( Z )-norendoxifen 导致显着高于 ( E )-norendoxifen 的血浆浓度和暴露量(AUC 值
