We report the identification of 13 (INCB3284) as a potent human CCR2 (hCCR2) antagonist. INCB3284 exhibited an IC50 of 3.7 nM in antagonism of monocyte chemoattractant protein-1 binding to hCCR2, an IC50 of 4.7 nM in antagonism of chemotaxis activity, an IC50 of 84 μM in inhibition of the hERG potassium current, a free fraction of 58% in protein binding, high selectivity over other chemokine receptors and G-protein-coupled receptors, and acceptable oral bioavailability in rodents and primates. In human clinical trials, INCB3284 exhibited a pharmacokinetic profile suitable for once-a-day dosing (T 1/2 = 15 h).
我们报告了13(INCB3284)作为一种有效的人CCR2(hCCR2)拮抗剂的鉴定结果。INCB3284在拮抗单核细胞趋化蛋白-1与hCCR2结合方面的IC50为3.7 nM,在拮抗趋化活性方面的IC50为4.7 nM,在抑制hERG钾电流方面的IC50为84 μM,蛋白结合的游离分数为58%,对其他趋化因子受体和G蛋白偶联受体具有高选择性,并且在啮齿动物和灵长类动物中具有可接受的口服生物利用度。在人体临床试验中,INCB3284表现出适合每日一次给药的药代动力学特征(T 1/2 = 15小时)。
