Both JNK and LRRK2 are associated with Parkinson's disease (PD), myocardial infarction (MI), 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)和其他医学疾病有关。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)。采用一种双齿配体结合策略,同时利用ATP铰链结合和ATP口袋外的独特蛋白表面位点,设计和鉴定了这种抑制剂。化合物6是一种强效的JNK3和适度的LRRK2双重抑制剂,其酶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,并被证明在代表性激酶家族的116个激酶面板中相对选择性较好。
