strategy for the treatment of a variety of pathologies, in particular inflammatory and autoimmune diseases. In this work, we designed and developed novel thieno[2,3d]pyrimidine derivatives, in order to explore their activity and selectivity as RIPK2 inhibitors. Primary in vitro evaluations of the new molecules against purified RIPKs (RIPK1-4) demonstrated outstanding inhibitory potency and selectivity for
在人类细胞中,受体相互作用蛋白激酶 2 (RIPK2) 主要介导含有核苷酸结合寡聚化结构域的受体 1 和 2 (NOD1/2) 的下游酶级联,这些受体是促炎信号传导的调节因子。因此,RIPK2的靶向抑制已被提议作为治疗多种病理,特别是炎症和自身免疫性疾病的药理学策略。在这项工作中,我们设计并开发了新型噻吩并[ 2,3d ]嘧啶衍生物,以探索它们作为RIPK2抑制剂的活性和选择性。针对纯化 RIPK (RIPK1-4) 的新分子的初步体外评估表明,其对 RIPK2 酶具有出色的抑制效力和选择性。此外,在活细胞中进行的针对 RIPK2-NOD1/2 信号通路功效的研究表明,它们的效力可以调整到低纳摩尔范围。这可以通过仅改变噻吩并[ 2,3d ]嘧啶支架的位置6处的取代来实现。最终评估了一组先导抑制剂对除 RIPK 之外的 58 种人类激酶的选择性,显示出极大的特异性。因此,我们获得了新的抑制剂
