The present invention relates to a novel heterocyclic compound, a pharmaceutical composition comprisining said compound, a method and use of said compound for clinical treatment of medical conditions which may benefit from immunomodulation, e.g. rheumatoid arthritis, multiple sclerosis, diabetes, asthma, transplantation, systemic lupus erythematosis and psoriasis. More particularly the present invention relates to novel heterocyclic compounds, which are CD80 antagonists capable of inhibiting the interactions between CD80 and CD28. A method of screening compounds for their ability of inhibiting ligand-induced co-stimulatory receptor internalization pathways in immune competent human cells is described. Said immune competent human cells are incubated at conditions capable of inducing co-stimulatory receptor internalization in the presence of at least one test compound and the suppression of the ligand-induced co-stimulatory receptor internalization determined. There is also described a kit for use in such a method, as well as an immunoregulatory drug capable of blocking down-modulation of a ligand-induced receptor.
本发明涉及一种新型杂环化合物,一种含有该化合物的药物组合物,以及该化合物的方法和用途,用于临床治疗可能从免疫调节中受益的医疗状况,例如类风湿性关节炎、多发性硬化症、糖尿病、哮喘、移植、系统性红斑狼疮和牛皮癣。更具体地,本发明涉及新型杂环化合物,这些化合物是CD80拮抗剂,能够抑制CD80和CD28之间的相互作用。还描述了一种筛选化合物的方法,用于抑制免疫能力人类细胞中配体诱导的共刺激受体内化途径的能力。在至少一种测试化合物的存在下,将这些免疫能力人类细胞孵育在能够诱导共刺激受体内化的条件下,并确定抑制配体诱导的共刺激受体内化。还描述了一种用于该方法的试剂盒,以及一种能够阻止配体诱导的受体下调的免疫调节药物。
