antagonist of CC chemokinereceptor 2 (CCR2), a class A GPCR that has been pursued as a therapeutic target in inflammation and immuno-oncology. Based on a known intracellularly binding CCR2 antagonist, several covalent derivatives were synthesized and characterized by radioligand binding and functional assays. These studies revealed compound 14 as an intracellular covalent ligand for CCR2. In silico
共价作用抑制剂构成了已获批准的小分子治疗药物的很大一部分,而且还在不断增长,同时也是各种体外和体内应用的有用工具。在这里,我们旨在开发 CC 趋化因子受体 2 (CCR2) 的共价拮抗剂,这是一种 A 类 GPCR,已被用作炎症和免疫肿瘤学的治疗靶点。基于已知的细胞内结合 CCR2 拮抗剂,合成了几种共价衍生物,并通过放射性配体结合和功能测定对其进行了表征。这些研究揭示了化合物14作为 CCR2 的细胞内共价配体。计算机建模和定点诱变证实了14与三个近端半胱氨酸残基之一形成共价键,可以互换接合。据我们所知,化合物14代表了第一个报道的 CCR2 共价配体。由于其独特的特性,它可能代表正在进行和未来 CCR2 药理学研究的有前途的工具。

A series of biarylsulfonamides was identified as hCCR2 receptor antagonist but suffered from high plasma protein binding resulting in a >100 fold shift in activity in a functional GTP gamma S assay run in tandem in the presence and absence of human serum albumin. Introduction of an aryl amide with ethylenediamine linker led to compounds with reduced shifts and improved activity in whole blood. (C) 2011 Elsevier Ltd. All rights reserved.

bioluminescence resonance energy transfer (BRET) assays. Here, we report the structure-based development of fluorescent ligands targeting the intracellular allostericbindingsite (IABS) of the CC chemokine receptor 2 (CCR2), a class A GPCR that has been pursued as a drug target in oncology and inflammation. Starting from previously reported intracellular CCR2 antagonists, several tetramethylrhodamine
