entities were prepared via Suzuki and S(N) reaction as AC-ring substrate mimetics of CYP17. The synthesised compounds 1-31 were tested for activity using human CYP17 expressed in Escherichia coli. Promising compounds were tested for selectivity against hepatic CYP enzymes (3A4, 2D6, 1A2, 2C9, 2C19, 2B6). Two potent inhibitors (27, IC50 = 373 nM/28, IC50 = 953 nM) were further examined in rats regarding their
通过Suzuki和S(N)反应制备新的化学实体,作为CYP17的AC环底物模拟物。使用在大肠杆菌中表达的人CYP17测试合成的化合物1-31的活性。测试了有前途的化合物对肝CYP酶(3A4、2D6、1A2、2C9、2C19、2B6)的选择性。在大鼠中进一步检查了两种强效抑制剂(27,IC50 = 373 nM / 28,IC50 = 953 nM)对血浆睾丸激素水平的影响及其药代动力学特性。化合物28具有与阿比特龙类似的活性,并显示出更好的药代动力学特性(更高的生物利用度,t(1/2)9.5 h对1.6 h)。对接研究揭示了两种不同于底物和类固醇抑制剂之一的新结合方式。
