The present invention relates to certain substituted oxadiazole, thiadiazole and triazole peptoids which are useful as inhibitors of human neutrophil elastase (HNE) for the treatment of HNE-mediated processes implicated in conditions such as adult respiratory distress syndrome, septic shock and multiple organ failure. A series of studies also have indicated the involvement HNE in myocardial ischemia-reperfusion injury, emphysema. HNE-mediated processes are implicated in other conditions such as arthritis, periodontal disease, glomerulonephritis, dermatitis, psoriasis, cystic fibrosis, chronic bronchitis, atherosclerosis, Alzheimer's disease, organ transplantation, corneal ulcers, and invasion behavior of malignant tumors.
本发明涉及某些取代的
噁唑烷、
噻唑烷和三唑烷肽类化合物,用作人类中性粒细胞
弹性蛋白酶(HNE)的
抑制剂,用于治疗HNE介导的过程,这些过程涉及成人呼吸窘迫综合症、脓毒性休克和多器官衰竭等疾病。一系列研究也表明HNE参与心肌缺血再灌注损伤、肺气肿等疾病。HNE介导的过程还涉及其他疾病,如关节炎、牙周病、肾小球肾炎、皮炎、
银屑病、囊性纤维化、慢性支气管炎、动脉粥样硬化、阿尔茨海默病、器官移植、角膜溃疡和恶性肿瘤的浸润行为。
