are substituted with one p- and one m-acetoxy group in two different aromatic rings, were synthesized. The E and Z isomers were isolated, and their identity was established by 1H NMR spectroscopy. A study of the structure-activity relationship was carried out with regard to estradiol receptor affinity in vitro, estrogenic and antiestrogenic properties (mouse), inhibition of the hormone-dependent human
合成了在两个不同的芳环中分别被一个对乙酰基和一个间乙酰氧基取代的1,1,2-三苯基丁-1-烯(E-和Z-10-12)。分离出E和Z异构体,并通过1 H NMR光谱确定它们的身份。研究了体外的雌二醇受体亲和力,雌激素和抗雌激素特性(小鼠),体外抑制激素依赖性人MCF7乳腺癌细胞系以及激素依赖性MXT乳腺的结构-活性关系。小鼠体内肿瘤。在测试的化合物中,(E)-和(Z)-1-(3-乙酰氧基苯基)-1-(4-乙酰氧基苯基)-2-苯基丁-1-烯+(E-10和Z-10)和( Z)-1-(3-乙酰氧基苯基)-1-苯基-2-(4-乙酰氧基苯基)-丁-1-烯(Z-12)被证明是部分抗雌激素药,可抑制MCF7细胞系。它们对小鼠的激素依赖性MXT乳腺癌发挥抑制生长的作用。在E-10和Z-10的情况下,此作用仅比1,1-双(4-乙酰氧基苯基)-2-苯基丁-1-烯(13)和他莫昔芬的作用稍弱。在所应用的实验条件下
