The synthesis of C(4)H and C(4)Me analogues of the JNK/p38 pathway activator anisomycin, based upon an aldol or Claisen construction of the C(3)–C(4) bond, has been demonstrated. The relative activation of the JNK/SAPK1 and p38/SAPK2 pathways in RAW macrophages by these analogues, and their synthetic precursors, has been assessed using immunoblot assays against phosphorylated c-Jun and MAPKAP-K2. These studies demonstrate that some of the synthetic C(4) analogues are also potent activators of these stress kinase pathways.
基于 C(3)-C(4) 键的醛醇或克莱森结构,我们合成了 JNK/p38 通路激活剂安诺霉素的 C(4)H 和 C(4)Me 类似物。利用针对磷酸化 c-Jun 和 MAPKAP-K2 的免疫印迹分析法,评估了这些类似物及其合成前体对 RAW 巨噬细胞中 JNK/SAPK1 和 p38/SAPK2 通路的相对激活作用。这些研究表明,一些合成的 C(4) 类似物也是这些应激激酶通路的强效激活剂。
