This invention relates to substituted benzanilides which are ligands, agonists or antagonists, of the CCR5 receptor. In addition, this invention relates to the treatment and prevention of disease states mediated by CCR5, including, but not limited to, asthma and atopic disorders (for example, atopic dermatitis and allergies), rheumatoid arthritis, sarcoidosis and other fibrotic diseases, atherosclerosis, psoriasis, autoimmune diseases such as multiple sclerosis, and inflammatory bowel disease, all in mammals, by the use of substituted benzanilides which are CCR5 receptor antagonists. Furthermore, since CD8+ T cells have been implicated in COPD, CCR5 may play a role in their recruitment and therefore antagonists to CCR5 could provide potential therapeutic in the treatment of COPD. Also, since CCR5 is a co-receptor for the entry of HIV into cells, selective receptor ligands may be useful in the treatment of HIV infection.
本发明涉及作为CCR5受体的配体、激动剂或拮抗剂的取代苯甲酰亚胺。此外,本发明还涉及通过使用作为CCR5受体拮抗剂的取代苯甲酰亚胺,治疗和预防由CCR5介导的疾病状态,包括但不限于哮喘和变应性疾病(例如,特应性皮炎和过敏症)、类风湿性关节炎、结节病和其他纤维化疾病、动脉粥样硬化、银屑病、自身免疫性疾病如多发性硬化症和炎症性肠病,所有这些疾病都发生在哺乳动物中。此外,由于CD8+ T细胞与慢性阻塞性肺病(COPD)有关,CCR5可能在其招募中发挥作用,因此CCR5的拮抗剂可能为COPD的治疗提供潜在的治疗方法。另外,由于CCR5是HIV进入细胞的共受体,选择性的受体配体可能在治疗HIV感染中是有用的。
