hit-to-lead optimization led to the discovery of a novel chemotype series exemplified by the trans racemic compound 11i. This series provided CXCR7 antagonists that block CXCL11- and CXCL12-induced ß-arrestin recruitment. Further structural modifications on the trisubstituted piperidine scaffold of 11i yielded compounds with high CXCR7 antagonistic activities and balanced ADMET properties. The effort described
趋化因子受体CXCR7,也称为ACKR3,是七种跨膜G蛋白偶联受体(GPCR),涉及多种病理,例如神经系统疾病,自身免疫性疾病和癌症。通过结合和清除趋化因子CXCL11和CXCL12,CXCR7调节它们的细胞外水平。在最初的高通量筛选活动中,出现了热门3。一触即发的优化导致发现了一种新型的化学型系列,例如反式外消旋化合物11i。该系列提供了可阻断CXCL11和CXCL12诱导的β-arrestin募集的CXCR7拮抗剂。11i的三取代哌啶骨架的进一步结构修饰产生具有高CXCR7拮抗活性和平衡ADMET性质的化合物。本文所述的努力最终导致了ACT-1004-1239(28f)的发现。ACT-1004-1239的生物学特性表明它是一种有效的,不可逾越的拮抗剂。在小鼠中口服ACT-1004-1239的剂量高达100 mg / kg导致血浆CXCL12浓度呈剂量依赖性增加。
