(E)-N-cyclopropyl-3-(3-fluorophenyl)but-2-enamide, has led to the discovery of the potent, centrallyactingmusclerelaxant (E)-2-(4,6-difluoro-1-indanylidene)acetamide, 17. Compound 17 also possesses potent antiinflammatory and analgesic activity. This paper describes the synthesis and the musclerelaxant, antiinflammatory, and analgesic structure-activity relationships of 17 and 67 of its analogues

described a new approach for the design of high–affinityCCR2antagonists, by taking their residence time (RT) on the receptor into account. Here, we report our findings on both structure–affinity relationship (SAR) and structure–kinetic relationship (SKR) studies for a series of 3-((inden-1-yl)amino)-1-isopropyl-cyclopentane-1-carboxamides as CCR2antagonists. SAR studies showed that this class of compounds

pointed to a critical role of the chemokine receptor 2 (CCR2) and chemokine ligand 2 (CCL2). However, one of the biggest problems of high-affinity inhibitors of CCR2 is their lack of efficacy in clinical trials. We report a new approach for the design of high-affinity and long-residence-timeCCR2antagonists. We developed a new competition association assay for CCR2, which allows us to investigate the relation
炎症性疾病(例如神经性疼痛,类风湿性关节炎和多发性硬化症)的临床前模型已指出趋化因子受体2(CCR2)和趋化因子配体2(CCL2)的关键作用。但是,CCR2高亲和力抑制剂的最大问题之一是它们在临床试验中缺乏功效。我们报告了一种新的方法来设计高亲和力和长时间驻留的CCR2拮抗剂。我们开发了一种新的CCR2竞争关联分析,使我们能够研究配体的结构与其受体停留时间的关系[即结构-动力学关系(SKR)],而不是传统的结构-亲和关系(SAR)。 。通过运用SAR和SKR的综合知识,我们能够重新评估作为CCR2拮抗剂的环戊胺的先导过程。1具有良好的结合力(K i = 6.8 nM),但停留时间却很短(2.4分钟)。但是,当优化还基于停留时间时,先导过程会产生化合物22a,这是一种新型的高亲和力CCR2拮抗剂(3.6 nM),停留时间为135分钟。
