Effective therapeutic agents are highly desired for immune-mediated allergic diseases. Herein, we report the design, synthesis, and structure–activity relationship of an o-aminopyridinyl alkyne series as novel orally bioavailable antiallergic agents, which was identified through phenotypic screening. Compound optimization yielded a highly potent compound 36, which effectively suppressed mast cell degranulation
免疫介导的过敏性疾病非常需要有效的治疗剂。在此,我们报告了邻氨基吡啶基炔系列作为新型口服生物可利用的抗过敏药物的设计、合成和构效关系,并通过表型筛选进行了鉴定。化合物优化产生了高效的化合物36 ,它以剂量依赖性方式有效抑制肥大细胞脱颗粒(RBL-2H3细胞的IC 50为2.54 nM;腹膜肥大细胞(PMC)为48.28 nM),具有良好的治疗指数。它还调节 IgE/Ag 刺激的 RBL-2H3 细胞中 FcεRI 介导的下游信号蛋白的激活。此外, 36在被动全身过敏反应(PSA)和屋尘螨(HDM)诱导的肺部过敏性炎症小鼠模型中表现出优异的体内药代动力学特性和抗过敏功效。此外,对激酶谱的初步分析确定了 Src 家族激酶作为36的潜在靶标。化合物36可能作为未来抗过敏药物发现的新的有价值的先导化合物。
