  鉴定有效和选择性的RIPK2抑制剂来治疗炎性疾病

  摘要：

  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。
