Animal models suggest that the chemokine ligand 2/CC‐chemokine receptor 2 (CCL2/CCR2) axis plays an important role in the development of inflammatory diseases. However, CCR2 antagonists have failed in clinical trials because of a lack of efficacy. We previously described a new approach for the design of CCR2 antagonists by the use of structure–kinetics relationships (SKRs). Herein we report new findings
动物模型表明趋化因子配体2 / CC-趋化因子受体2(CCL2 / CCR2)轴在炎症性疾病的发展中起着重要作用。但是,由于缺乏疗效,CCR2拮抗剂在临床试验中失败了。先前,我们通过使用结构动力学关系(SKR)描述了一种设计CCR2拮抗剂的新方法。本文中,我们报告了有关参考化合物MK-0048,其非对映异构体及其结构类似物(如CCR2拮抗剂)的结构亲和力关系(SAR)和SKR的新发现。4-芳基哌啶基的SAR值表明在3位的亲脂性氢键接受取代基是有利的。但是,SKRs建议具有一定大小的亲脂基团[例如3-Br:K i = 2.8 nM,停留时间(t res)= 243分钟;3- i Pr:K i= 3.6 n M,t res= 266分钟]。另外,其他取代基和分子的进一步优化,同时将羧酸保持在3位,也可以延长t res;这在MK-0483(K i = 1.2 n M,t res = 724 min)和紧密的类似物(K
