  四氢喹啉的发现和Benzomorpholines作为新的有效RORγt激动剂小号

  摘要：

  视黄酸受体相关的孤儿受体γt（RORγt）是调节Th17细胞分化和白介素17（IL-17）产生的重要核受体。RORγt激动剂可增加RORγt的基础活性，并可能为癌症免疫治疗提供潜在途径。在此，在室内文库筛选期间，将命中化合物1鉴定为弱RORγt激动剂。LHS核心1的变化导致鉴定了四氢喹啉化合物6作为部分RORγt激动剂（最大作用= 39.3％）。探索了LHS核心，酰胺连接基和RHS芳基磺酰基部分的取代基之间的详细结构-活性关系，并发现了一系列新型的四氢喹啉和苯并吗啉作为有效的RORγt激动剂。四氢喹啉化合物8g（EC 50 = 8.9±0.4 nM，最大作用= 104.5％）和苯并吗啉化合物9g（EC 50 = 7.5±0.6 nM，最大作用= 105.8％）是具有高RORγt激动活性的代表性化合物。双重FRET检测，在基于细胞的Gal4报告基因检测和Th17细胞分化检测中显示出良好的活性（300

  implicated in numerous chronic inflammatory conditions. Herein, a pyrido[2,3-d]pyrimidin-7-one based class of RIPK2 kinase and NOD2 cell signaling inhibitors is described. For example, 33 (e.g. UH15–15) inhibited RIPK2 kinase (IC50 = 8 ± 4 nM) and displayed > 300-fold selectivity versus structurally related activin receptor-like kinase 2 (ALK2). This molecule blocked NOD2-dependent HEKBlue NF-κB activation

  受体相互作用蛋白激酶 2 (RIPK2) 是一种参与促炎核苷酸结合寡聚化结构域 (NOD) 细胞信号转导的酶，该信号通路与许多慢性炎症状况有关。本文描述了基于 pyrido[2,3-d]pyrimidin-7-one 的一类 RIPK2 激酶和 NOD2 细胞信号传导抑制剂。例如，33 (例如UH15 – 15 ) 抑制 RIPK2 激酶 (IC 50  = 8 ± 4 nM) 并显示出与结构相关的激活素受体样激酶 2 (ALK2) 相比 > 300 倍的选择性。该分子阻断 NOD2 依赖性 HEKBlue NF-κB 活化（IC 50 = 20 ± 5 nM）和 CXCL8 生产（浓度 > 10 nM）。分子对接表明，Ser25 在富含甘氨酸的环中的参与可能会提供比 ALK2 更高的选择性，并且守门员和 αC 螺旋之间区域的最佳占据可能有助于有效的 NOD2 细胞信号传导抑制。最后，该化合物还表现出良好的体外ADME
