1-Aryl-4-substituted isoquinolines analogues of Formula (I) and Formula (II) are provided, as follows : wherein R1, R2, R3, R8, R9, A and Ar are defined herein. Such compounds are ligands of C5a receptors. Preferred compounds of Formula (I) and (II) 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 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 1-aryl-4-substituted isoquinolines, which are useful as probes for the localization of C5a receptors.
提供了Formula (I)和Formula (II)的1-芳基-4-取代异喹啉类似物,具体如下:其中R1、R2、R3、R8、R9、A和Ar在此处定义。这些化合物是C5a受体的配体。Formula (I)和(II)的优选化合物与C5a受体结合亲和力高,并在C5a受体上表现为中性拮抗剂或逆向激动剂活性。本发明还涉及包含这些化合物的药物组合物,以及利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,本发明提供了标记的1-芳基-4-取代异喹啉,可用作C5a受体的定位探针。
