in the initial compounds of this series with a pyridone ring resulted in the mitigation of cell cytotoxicity. Further systematic structure–activity relationship (SAR) efforts driven by structural biology studies led to the discovery of pyridone 34, a potent pan-JAK inhibitor with good selectivity, long lung retention time, low oral bioavailability, and proven efficacy in the lipopolysaccharide-induced
Janus激酶(JAKs)在调节与哮喘和慢性阻塞性肺疾病有关的炎性细胞因子的表达和功能中起关键作用。本文描述了一系列适合吸入给药的新型嘌呤酮JAK抑制剂的设计,合成和药理学评估。用吡啶酮环代替该系列起始化合物中存在的咪唑并吡啶铰链结合基序可减轻细胞的细胞毒性。由结构生物学研究推动的进一步的系统构效关系(SAR)的努力导致发现了吡啶酮34,一种有效的泛JAK抑制剂,具有良好的选择性,较长的肺保留时间,较低的口服生物利用度,并且在通过吸入途径经脂多糖诱导的气道炎症大鼠模型中被证明具有疗效。
