pathologic processes. We synthesized novel 11H-indeno[1,2-b]quinoxalin-11-one oxime analogs and tryptanthrin-6-oxime (indolo[2,1-b]quinazoline-6,12-dion-6-oxime) and evaluated their effects on JNK activity. Several compounds exhibited sub-micromolar JNK binding affinity and were selective for JNK1/JNK3 versus JNK2. The most potent compounds were 10c (11H-indeno[1,2-b]quinoxalin-11-one O-(O-ethylcarboxymethyl)
c-Jun N末端激酶(JNK)在许多生理和病理过程中起着核心作用。我们合成了新型11H-茚并[1,2-b]喹喔啉-11-一肟类似物和色胺素6-肟(吲哚[2,1-b]喹唑啉-6,12-dion-6-肟),并对其进行了评估。对JNK活性的影响。几种化合物表现出亚微摩尔的JNK结合亲和力,对JNK1 / JNK3和JNK2具有选择性。最有效的化合物是10c(11H-茚并[1,2-b]喹喔啉-11-一个O-(O-乙基羧甲基)肟)和色胺酮-6-肟,它们的JNK1和JNK3的解离常数(Kd)为分别为22和76 nM,以及150和275 nM。分子建模表明在JNK催化位点的结合相互作用的模式,并且所选的肟衍生物是潜在的竞争性JNK抑制剂。化合物的JNK结合活性与其抑制脂多糖(LPS)诱导的人单核THP-1Blue细胞和白介素6(IL-β)中核因子-κB/活化蛋白1(NF-κB/ AP-1)活化的能力有关。
