diastereomers. The binding affinity of these compounds to the calf uterine estrogen receptor was measured relative to that of [3H]estradiol by a competitive binding assay. All test compounds showed relative binding affinity (RBA) values between 32 and less than 0.01% that of estradiol. Only meso-3,4-bis(2,4-dihydroxyphenyl)hexane (16) showed an estrogen receptor binding affinity comparable to that
描述了对称的3,3'-和2,2'-双取代的内消旋己烯醇衍生物的合成[3,3'-取代基:OH(1),F(2),Cl(3),Br(4),I (5),CH2N(CH3)2(6),CH3(7),CH2OCH3(8),CH2OC2H5(9),CH2OH(10),NO2(11),NH2(12),N(CH3)2(13 ),COCH3(14)和C2H5(15);2,2'-取代基:OH(16),F(17),Cl(18),Br(19),CH3(20)和C2H5(21)]。1-3的合成是通过将苯乙酮与TiCl4 / Zn还原偶联并随后将顺式3,4-二苯基己基-3-烯氢化而完成的。通过取代己烯雌酚获得化合物4-15,而通过将1-苯基-1-丙醇与TiCl3 / LiAlH4偶联并分离内消旋非对映异构体来合成化合物16-21。通过竞争性结合测定法测量了这些化合物对小牛子宫雌激素受体的结合亲和力与[3H]雌二醇的结合亲
