direct inhibitors of NOD2 have not been described due to technical challenges of targeting the oligomeric protein complex. Receptor interacting protein kinase 2 (RIPK2) is an intracellular serine/threonine/tyrosine kinase, a key signaling partner, and an obligate kinase for NOD2. As such, RIPK2 represents an attractive target to probe the pathological roles of NOD2 pathway. To search for selective RIPK2
NOD2(含有核苷酸结合的寡聚域的蛋白质2)是一种内部模式识别受体,可识别细菌肽聚糖并刺激宿主免疫反应。NOD2通路功能障碍与许多自身炎症性疾病有关。迄今为止,由于靶向寡聚蛋白复合物的技术挑战,尚未描述NOD2的直接抑制剂。受体相互作用蛋白激酶2(RIPK2)是细胞内丝氨酸/苏氨酸/酪氨酸激酶,是关键的信号传导伴侣,也是NOD2的专一性激酶。因此,RIPK2代表了一个有吸引力的靶标,以探索NOD2途径的病理作用。为了寻找选择性的RIPK2抑制剂,我们采用了虚拟文库筛选(VLS)和基于结构的设计,最终导致了有效而选择性的RIPK2抑制剂8具有优异的口服生物利用度,用于评估RIPK2在各种体外测定以及离体和体内药效学模型中的抑制作用。
