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 internalisation pathways in immune competent human cells is described. Said immune competent human cells are incubated at conditions capable of inducing co-stimulatory receptor internalisation in the presence of at least one test compound and the suppression of the ligand-induced co-stimulatory receptor internalisation 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.
本发明涉及一种新颖的杂环化合物,一种包含该化合物的药物组合物,以及该化合物在临床治疗可能受益于免疫调节的医疗状况的方法和用途,例如类风湿关节炎、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,本发明涉及一种新颖的杂环化合物,这些化合物是CD80拮抗剂,能够抑制CD80和CD28之间的相互作用。描述了一种筛选化合物的方法,用于评估它们抑制免疫能力的能力,即抑制免疫能力的人类细胞内的配体诱导的共刺激受体内化途径。在至少一种试验化合物存在的条件下,孵育这些免疫能力的人类细胞,能够诱导共刺激受体内化,并确定抑制配体诱导的共刺激受体内化。还描述了一种用于此类方法的试剂盒,以及一种能够阻断配体诱导受体下调的免疫调节药物。
