rings, were synthesized. The occurring E and Z isomers were isolated, and their identity was established by 1H NMR spectroscopy. A study on structure-activity relationship was carried out with regard to estradiol receptor affinity in vitro, estrogenic and antiestrogenic properties in the immature mouse, and inhibition of the hormone-dependent MXT mammary tumor of the mouse in vivo. Among the tested compounds
1,1,2-三苯基丁-1-烯(26-35),在两个芳族化合物中被一个或两个3,4-二乙酰氧基或一个3,4-二乙酰氧基和一个3-或4-乙酰氧基取代环,被合成。分离出现的E和Z异构体,并通过1H NMR光谱确定其身份。进行了结构-活性关系的研究,涉及体外雌二醇受体亲和力,未成熟小鼠的雌激素和抗雌激素特性以及体内抑制小鼠激素依赖性MXT乳腺肿瘤。在测试的化合物中,大多数1,1,1-二取代的1,1,2-三苯基丁-1-烯(29,Z-30,Z,E-31)和(E)-1-(3-乙酰氧基苯基)- 1-苯基-2-(3,4-二乙酰氧基苯基)丁-1-烯(E-35)及其各自的Z异构体(Z-35)发挥抗雌激素特性。化合物Z-30,Z,E-31,Z-35,E-35抑制激素依赖性MXT肿瘤的生长。E-35显示出在治疗过程中最佳的抗肿瘤作用而没有雌激素副作用。
