(3b), Et (3c), Prop (3d), But (3e)) were synthesized by reaction of 1,2-bis(4-methoxyphenyl)ethanone with the appropriate alkyl halide, followed by a Grignard reaction with 4-methoxyphenylmagnesium bromide, dehydration with phosphoric acid or hydrobromic acid, and ether cleavage with BBr(3). The compounds were tested for estrogen receptor (ER) binding affinity in a competition experiment with radio labeled
1,1,2-三(4-羟苯基)乙烯3a(烷基= Me(3b),Et(3c),Prop(3d),But(3e))的C2-烷基取代的衍生物是通过1的反应合成的,2-双(4-甲氧基苯基)乙酮与适当的烷基卤化物,然后与4-甲氧基苯基溴化镁进行格氏反应,用磷酸或氢溴酸脱水,并用BBr(3)裂解。在与放射性标记的雌二醇([(3)H] -E2)的竞争实验中测试了这些化合物的雌激素受体(ER)结合亲和力,以及在ER阳性MCF-7-2a细胞系中的基因激活。所有化合物均显示出高受体结合亲和力(RBA值:3b(52.1%)> 3a(45.5%)> 3c(29.6%)> 3d(4.03%)> 3e(0.95%))。对激素依赖性MCF-7-2a乳腺癌细胞进行的测试(用质粒ERE(wtc)luc稳定转染)显示,所有1,1,2-三(4-羟苯基)乙烯拮抗1 nM雌二醇(E2)的作用。化合物3b(IC(50)= 15 nM)和3c(IC(50)=
