The present invention provides compounds of formula I:
1
wherein G is a small group selected from hydrogen or C
1-3
alkyl, Q is pyridine or pyrimidine, and R
1
-R
3
are as defined in the specification. These compounds are selective JNK inhibitors showing good activity against the three isoforms of JNK (JNK1, JNK2 and JNK3) and relatively low activity against p38 kinase. The compounds are therefore useful for treating JNK-mediated diseases, especially neurodegenerative diseases in which all three JNK isoforms are implicated.
本发明提供了I式化合物:1其中G是氢或C1-3烷基中的小基团,Q是
吡啶或
嘧啶,R1-R3如规范中所定义。这些化合物是选择性JNK
抑制剂,对JNK的三个亚型(JNK1、JNK2和JNK3)表现出良好的活性,并对p38激酶的活性相对较低。因此,这些化合物可用于治疗JNK介导的疾病,特别是所有三个JNK亚型都涉及的神经退行性疾病。
