by the lack of suitable chemical tools with a range of pharmacological profiles. A high-throughput screen was conducted to discover novel chemical matter with the potential to modulate CXCR7 receptor activity. This led to the identification of a series of diphenylacetamides confirmed in a CXCL12 competition assay indicating receptor binding. Further evaluation of this series revealed a lack of activity
非典型趋化因子受体CXCR7已在包括免疫疾病和心脏病在内的各种疾病中得到了研究。缺乏适当的具有多种药理学特征的化学工具限制了阐明CXCR7的作用。进行了高通量筛选,以发现可能调节CXCR7受体活性的新型化学物质。这导致鉴定出一系列在CXCL12竞争试验中证实的表明受体结合的二苯乙酰胺。对该系列的进一步评估显示,在测量β-arrestin募集的功能测定中缺乏活性。最有力的代表化合物10(K i = 597 nM)在β-arrestin分析中被确定为拮抗剂(IC50 = 622 nM)。据我们所知,这是第一个报道的CXCR7小分子β-arrestin拮抗剂,可作为体外化学工具来阐明CXCL12置换与β-arrestin拮抗作用在诸如心脏损伤等疾病模型中的适用性,并作为起点针对用于研究CXCR7受体药理的体内工具化合物的命中优化。
