The present invention provides a compound having excellent JAK3 inhibitory activity and being useful as an active ingredient of an agent for treating and/or preventing various immune diseases including autoimmune diseases, inflammatory diseases, and allergic diseases.
As a result of investigations with respect to novel condensed heterocyclic derivatives, the inventors have verified that a condensed pyridine compound has excellent JAK3 inhibitory activity, thereby completing the present invention.
More specifically, it has been verified that since the compound according to the present invention has inhibitory activity against JAK3, the compound is useful as an active ingredient of an agent for treating or preventing diseases caused by undesirable cytokine signal transduction (e.g., rejection during live organ/tissue transplantation, autoimmune diseases, asthma, atopic dermatitis, rheumatism, psoriasis and atherosclerotic disease), or diseases caused by abnormal cytokine signal transduction (e.g., cancer and leukemia).
本发明提供了一种化合物,该化合物具有优异的 JAK3 抑制活性,可用作治疗和/或预防各种免疫疾病(包括自身免疫性疾病、炎症性疾病和过敏性疾病)的药物的活性成分。
通过对新型缩合杂环衍生物的研究,本发明者验证了一种缩合吡啶化合物具有优异的 JAK3 抑制活性,从而完成了本发明。
更具体地说,由于根据本发明的化合物对 JAK3 具有抑制活性,因此该化合物可用作治疗或预防由不良细胞因子信号转导引起的疾病(如:活体器官/组织过程中的排斥反应)的制剂的活性成分、活体器官/组织移植过程中的排斥反应、自身免疫性疾病、哮喘、特应性皮炎、风湿病、牛皮癣和动脉粥样硬化疾病),或由异常细胞因子信号转导引起的疾病(如癌症和白血病)。
