    • Disclosed are conjugates exhibiting VLA-4 antagonistic properties. Certain of these conjugates also inhibit leukocyte adhesion and, in particular, leukocyte adhesion mediated by VLA-4. The conjugates of this invention are characterized as containing more than one VLA-4 inhibiting compound covalently attached to a bio-compatible polymer, such as polyethylene glycol. Conjugates of the invention are defined by formula I, wherein A, B, and q are described in the specification. Such conjugates 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 conjugates can also be administered for the treatment of inflammatory brain diseases such as multiple sclerosis.
    • 公开了表现出VLA-4拮抗性质的缀合物。 这些缀合物中的某些也抑制白细胞粘附,特别是由VLA-4介导的白细胞粘附。 本发明的缀合物的特征在于含有多于一种共价连接到生物相容性聚合物如聚乙二醇的VLA-4抑制化合物。 本发明的缀合物由式I定义,其中A,B和q在说明书中描述。 这样的缀合物可用于治疗哺乳动物患者(例如人,例如哮喘,阿尔茨海默病,动脉粥样硬化,艾滋病痴呆,糖尿病,炎性肠病,类风湿性关节炎,组织移植,肿瘤转移和心肌缺血)中的炎性疾病。 也可以将缀合物用于治疗炎性脑疾病如多发性硬化症。
