Further derivatives (formyl, hydroxymethyl, oxirane, mercapto) were prepared from 4-bromotamoxifen via the 4-lithio derivative. Several of the derivatives (Br, I, SMe, SOMe, SO2Me, oxirane, CHO, CH2OH) displayed a higher affinity for estrogen receptors (ER) of calf uterine cytosol than did tamoxifen, but there was no relationship between affinity to ER and the ability to inhibit the growth of the MCF-7
描述了在1-苯环的4-位上取代的他莫昔芬衍生物的范围。合成4-碘-,4-溴-和4-(甲硫基)他莫昔芬的关键步骤是1,2-二芳基丁酮与(4-卤代苯基)锂或[4-(甲硫基)苯基]镁的反应溴化物。使用4-(甲硫基)他莫昔芬的氧化前体制备甲基亚磺酰基和甲基磺酰基衍生物。由4-溴苯莫西芬经由4-硫代衍生物制备其他衍生物(甲酰基,羟甲基,环氧乙烷,巯基)。几种衍生物(Br,I,SMe,SOMe,SO2Me,环氧乙烷,CHO,CH2OH)对小牛子宫细胞溶质的雌激素受体(ER)的亲和力高于他莫昔芬,但对ER的亲和力与体外抑制MCF-7乳腺癌细胞系生长的能力。
