coumarines 1 and 2 significantly inhibit 17β-HSD1 in a recombinant enzyme assay, with high selectivity against 17β-HSD2. We postulated that the introduction of various p-substituted phenyl moieties to position 6 or 7 of the coumarin core using the Suzuki-Miyaura cross-coupling reaction would provide mimetics of steroidal structures with improved inhibition of 17β-HSD1. The best inhibitor in the series
17β-羟基类固醇脱氢酶1(17β-HSD1)是一种酶,可催化NADPH依赖性的弱雌激素雌酮还原为最有效的雌激素雌二醇,后者通过雌激素受体发挥增殖作用。17β-HSD1在雌激素反应性组织中的过表达与激素依赖性疾病的发展有关,例如乳腺癌和子宫内膜异位症。因此,17β-HSD1代表了开发新疗法的诱人靶标。我们发现,在重组酶分析中,简单的香豆素1和2可以显着抑制17β-HSD1,对17β-HSD2具有高选择性。我们假设引入了各种p-使用Suzuki-Miyaura交叉偶联反应将香豆素核心的6或7位取代的苯基部分提供类固醇结构的模拟物,对17β-HSD1的抑制作用得到改善。该系列中最好的抑制剂被证明是6a,IC 50为270 nM,对17β-HSD1的选择性比对17β-HSD2的要好,并且对α和β雌激素受体的选择性也很高。
