rCYP11B1 inhibition led to compound 8 as a new promising lead compound. Significant improvements compared to starting point IV were achieved regarding inhibitory potency against both human and rat CYP11B1 (IC50 values of 2 and 163 nM, respectively) as well as selectivity over hCYP19 (IC50 = 1900 nM). Accordingly, compound 8 was around 7- and 28-fold more potent than metyrapone regarding the inhibition
11日的抑制β羟化酶是用于治疗库欣综合征,特别是复发和亚临床病例有希望的策略。为在大鼠中获得概念验证,已努力确定抑制人和大鼠CYP11B1的新型先导化合物。对h CYP11B1,h CYP11B2和h CYP19(化合物IV)的强效混杂抑制剂的修饰表现出中度的r CYP11B1抑制作用,导致化合物8作为一种新的有前途的先导化合物。与起始点IV相比,对人和大鼠CYP11B1的抑制效力均获得了显着改善(IC 50值分别为2和163 nM)以及在h CYP19上的选择性(IC 50 = 1900 nM)。因此,就抑制人和大鼠CYP11B1而言,化合物8的效力比甲吡酮高约7倍和28倍,并且相对于h CYP11B2表现出相当的选择性(SF为3.5对4.9)。随着对该新的先导化合物8的进一步优化,预期将发现具有令人满意的概况的候选药物。
