alkylamino residues, designed as estrogen receptor (ER) binding ligands, were successfully synthesized through the McMurry coupling reaction of substituted benzaldehyde/substituted benzophenones and 2-hydroxyphenyl-7-methoxy-chroman-4-one in presence of lithium aluminum hydride and titanium (IV) chloride (LAH-TiCl(4)). Self-coupling of carbonyl reactants led to the formation of several side products. The
设计成雌激素受体的7-甲氧基-4-(4-甲氧基亚苄基)-2-取代的苯基-苯并吡喃I和4- [双-(4-甲氧基苯基)-亚甲基-2-取代的苯基-苯并吡喃II,带有不同的烷基氨基残基,被设计为雌激素受体( ER)的结合配体是在氢化铝锂和氯化钛(IV)(LAH-TiCl( 4))。羰基反应物的自偶联导致形成几种副产物。评价原型的相对结合亲和力(RBA),以及它们的雌激素和抗雌激素活性。用化合物3、7a,7b,7c,8和10a观察到高水平的雌激素活性(> 50%增幅),以及它们的部分雌激素拮抗活性(> 或在子宫水平上为15%)表示化合物的成功设计。化合物4、7a,7b,7c和10a还具有显着的抗人腺癌细胞系(MCF-7细胞系)抗癌活性,这可能与其雌激素依赖性作用有关。
