  Disclosed are compounds which bind α4 integrins, preferably VLA-4. Certain of these compounds also inhibit leukocyte adhesion and, in particular, leukocyte adhesion mediated by α4 integrins, preferably VLA-4. Such compounds are useful in the treatment of inflammatory diseases in a mammalian patient, e.g., human, such as asthma, Alzheimer's disease, atherosclerosis, AIDS dementia, diabetes, inflammatory bowel disease, rheumatoid arthritis, tissue transplantation, tumor metastasis and myocardial ischemia. The compounds can also be administered for the treatment of inflammatory brain diseases such as multiple sclerosis.

  本文披露了结合α4整合素的化合物，最好是VLA-4。其中某些化合物还抑制白细胞粘附，特别是由α4整合素介导的白细胞粘附，最好是VLA-4。这些化合物在治疗哺乳动物患者（例如人类）的炎症性疾病中很有用，如哮喘、阿尔茨海默病、动脉粥样硬化、艾滋病痴呆、糖尿病、炎症性肠病、类风湿关节炎、组织移植、肿瘤转移和心肌缺血。这些化合物也可用于治疗炎症性脑部疾病，如多发性硬化症。
