The present invention relates to selected (R)-2-phenyl-propionamides and (R)-2-phenyl-sulfonamides with a hydrogen bond acceptor atom/group in a well defined position in the chemical space. 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.
本发明涉及在
化学空间中特定位置具有氢键受体原子/基团的选择性(R)-2-苯基-丙酰胺和(R)-2-苯基-磺酰胺。这些化合物表现出对C5a诱导的人类PMN趋化的惊人的强效抑制作用。本发明的化合物绝对不具有CXCL8抑制活性。该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活化的病理过程中非常有用。特别是,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非常有用。
