Both JNK and LRRK2 are associated with Parkinson's disease (PD), myocardial infarction (Ml), and other medical disorders. Here we report a reasonably selective and potent kinase inhibitors (e.g., compounds 6 and 10) that bound to both JNK and LRRK2 (a dual inhibitor). A bidentate-binding strategy that simultaneously utilized the ATP hinge binding and a unique protein surface site outside of the ATP pocket was applied to the design and identification of this kind of inhibitor. Compound 6 was a potent JNK3 and modest LRRK2 dual inhibitor with an enzyme IC50 value of 12 nM and 99 nM (LRRK2-G2019S), respectively. 6 also exhibited good cell potency, inhibited LRRK2:G2019S induced mitochondrial dysfunction in SHSY5Y cells, and was demonstrated to be reasonably selective against a panel of 116 kinases from representative kinase families.
JNK和LRRK2都与帕
金森病(PD)、心肌梗死(MI)和其他医学疾病相关联。在这里,我们报告了一种相对选择性和有效的激酶
抑制剂(例如,化合物6和10),它们结合了JNK和LRRK2(双重
抑制剂)。采用一种双齿结合策略,同时利用
ATP铰链结合和
ATP口袋外的独特蛋白表面位点,用于设计和识别这种
抑制剂。化合物6是一种强效的JNK3和适度的LRRK2双重
抑制剂,酶IC50值分别为12 nM和99 nM(LRRK2-G2019S)。6还表现出良好的细胞效力,在SHSY5Y细胞中抑制了LRRK2:G2019S诱导的线粒体功能障碍,并被证明对来自代表性激酶家族的116种激酶面板具有相当的选择性。
