estrone into biologically active estradiol. In this study, a library of fused (di)cycloalkeno thieno[2,3-d]pyrimidin-4(3H)-one based compounds was synthesized, and the biological activities against 17β-HSD1 in a cell-free and in a cell-based assay were evaluated. Several thieno[2,3-d]pyrimidin-4(3H)-one based compounds, at 0.1 and 1 μM test concentrations, were found to be potent 17β-HSD1 inhibitors.
许多乳腺肿瘤是激素依赖性的,雌激素,尤其是雌二醇(E2),在其生长和发育中起关键作用。17β-羟基类固醇脱氢酶1(17β-HSD1)是女性性类固醇生物合成中的关键酶,可催化NADPH依赖性雌激素还原为具有生物活性的雌二醇。在这项研究中,合成了一个融合的(di)cycloalkeno thieno [2,3- d ] pyrimidin-4(3 H)-one为基础的化合物的文库,并在无细胞和有毒的条件下针对17β-HSD1的生物活性。对基于细胞的测定进行了评估。几种噻吩并[2,3- d ]嘧啶-4(3 H测试浓度为0.1和1μM的基于1的化合物是有效的17β-HSD1抑制剂。例如,4-(3-羟基苯硫基)-1,2,7,8,9,10,11,13-八氢-13-氧代-[1]苯并噻吩并[2',3':4,5]-嘧啶基[1,2 - a ]氮杂-3-甲醛(7f)是迄今为止最有效的非甾体17β-HSD1抑制剂之一,在0
