ERK1/2 kinase is a key downstream node of the RAS-RAF-MEK-ERK signaling pathway. A highly potent and selective ERK1/2 inhibitor is a promising option for cancer treatment that will provide a potential solution for overcoming drug resistance. Herein we designed and synthesized a novel scaffold featuring a pyrrole-fused urea template. The lead compound, SHR2415, was shown to be a highly potent ERK1/2 inhibitor that exhibited high cell potency based on the Colo205 assay. In addition, SHR2415 displayed favorable PK profiles across species as well as robust efficacy in a mouse Colo205 xenograft model.
ERK1/2激酶是RAS-RAF-MEK-ERK信号通路的关键下游节点。一种高效且选择性的ERK1/2抑制剂是癌症治疗的一个有前景的选择,它将为克服耐药性提供潜在的解决方案。在此,我们设计并合成了一种具有吡咯稠合脲模板的新型骨架。先导化合物SHR2415被证明是一种高效的ERK1/2抑制剂,基于Colo205试验显示出高细胞活性。此外,SHR2415在不同物种中表现出良好的药代动力学特征,并且在小鼠Colo205异种移植模型中具有强大的疗效。
