etiology of estrogen-dependent diseases (EDD) like breast cancer and endometriosis. 17β-Hydroxysteroid dehydrogenase type 1 (17β-HSD1) catalyses the last step of E2 biosynthesis and is thus a promising target for the treatment of EDD. The previously described bicyclic substituted hydroxyphenylmethanones (BSHs) display high inhibitory potency towards human 17β-HSD1, but marginal activity towards rodent
17β-雌二醇(E2)是最有效的人类雌激素,已知参与雌激素依赖性疾病(EDD)的病因,如乳腺癌和子宫内膜异位症。1型17β-羟基类固醇脱氢酶(17β-HSD1)催化E2生物合成的最后一步,因此是治疗EDD的有希望的靶标。先前描述的双环取代的羟苯基甲烷(BSHs)对人17β-HSD1具有高抑制力,但对啮齿动物17β-HSD1的活性却很小,这排除了在动物子宫内膜异位症模型中进行原理研究的证据。这项工作的目的是在BSHs类中进行结构优化,以增强对啮齿动物(小鼠和大鼠)17β-HSD1的抑制活性,同时保持对人类酶的活性。在苯甲酰基部分上引入氟原子产生具有所需性质的化合物。应用分子对接和同源性建模来阐明结合模式和种间活性差异。化合物33是两者的最有效的抑制剂的人类和大鼠17β-HSD1是最新的(IC 50 = 2nM的和97 nM的,分别地)。
