, A and Ar are defined herein. Such compounds are ligands of C5a receptor. Preferred compounds of Formula I bind to C5a receptors with high affinity and exhibit neutral antagonist or inverse agonist activity at C5a receptors. The present invention also relates to pharmaceutical compositions comprising such compounds, and to the use of such compounds in treating a variety of inflammatory, cardiovascular, and immune system disorders. In addition, the present invention provides labeled 3-substituted-6-aryl pyridines, which are useful as probes for the localization of C5a receptors.
本发明提供了式I的3-取代-6-芳基吡啶化合物:
其中,R1、R2、R3、R8、R9、A和Ar的定义如下。这些化合物是C5a受体的配体。式I的优选化合物具有高亲和力结合C5a受体,并在C5a受体上表现出中性拮抗剂或反向激动剂的活性。本发明还涉及包含这些化合物的制药组合物,以及使用这些化合物治疗各种炎症、心血管和免疫系统疾病的用途。此外,本发明还提供了标记的3-取代-6-芳基吡啶化合物,可用作C5a受体定位的探针。
