The present invention relates to selected (R)-arylalkylamino derivatives of formula (I), in which R, R1 and Ar are as defined in the claims. These compounds show a surprising potent inhibitory effect on C5a induced human PMN chemotaxis. The compounds of the invention absolutely lack of CXCL8 inhibitory activity. Said compounds are useful in the treatment of pathologies depending on the chemotactic activation of neutrophils and monocytes induced by the fraction C5a of the complement. In particular, the compounds of the invention are useful in the treatment of sepsis, psoriasis, rheumatoid arthritis, ulcerative colitis, acute respiratory distress syndrome, idiopathic fibrosis, glomerulonephritis and in the prevention and treatment of injury caused by ischemia and reperfusion.
本发明涉及公式(I)中选择的(R)-芳基烷基
氨基衍
生物,其中R、R1和Ar的定义如权利要求中所述。这些化合物表现出惊人的抑制C5a诱导的人类PMN趋化的强效作用。本发明的化合物绝对缺乏CXCL8抑制活性。所述化合物在治疗依赖于补体C5a诱导的中性粒细胞和单核细胞趋化激活的病理状态中有用。特别地,本发明的化合物在治疗败血症、
银屑病、类风湿性关节炎、溃疡性结肠炎、急性呼吸窘迫综合症、特发性纤维化、肾小球肾炎以及缺血再灌注引起的损伤的预防和治疗中有用。
