tyrosine kinase (Syk) is a promising strategy for the treatment of various allergic and autoimmune disorders such as asthma, rheumatoid arthritis, and allergic rhinitis. Previously, a Syk inhibitor with novel indazole scaffold was discovered by structure‐based virtual screening. Herein, the structure–activity relationship of the indazole Syk inhibitors was investigated. Several new inhibitors demonstrated

酪氨酸激酶 (Syk) 是治疗各种过敏性和自身免疫性疾病(如哮喘、类风湿性关节炎和过敏性鼻炎)的有前景的策略。此前,通过基于结构的虚拟筛选发现了一种具有新型
吲唑支架的
Syk 抑制剂。在此,研究了
吲唑 Syk 抑制剂的构效关系。几种新的
抑制剂显示出对 Syk 的有效活性。特别是,化合物 18c 显示出良好的 Syk 抑制活性 (IC50 = 1.2 µM),代表了用于进一步优化的良好先导化合物。
