through the gp130 receptor. Model compounds of madindolines were synthesized and tested for thiol reactivity. The heterocyclic moiety of madindoline was shown to form thiol adducts via the Savige-Fontana reaction. The enedione moiety was found to be unreactive toward simple thiols unless the quaternary center was removed. Using the powerful Moore reaction, we have synthesized (+/-)-madindoline A and B in
[反应:见正文]据信,马丹多啉抑制通过gp130受体的细胞因子信号传导。合成了金刚烷胺的模型化合物并测试了硫醇反应性。马丹多林的杂环部分经Savige-Fontana反应显示形成硫醇加合物。发现烯二酮部分对简单的硫醇没有反应,除非除去四元中心。使用强大的摩尔反应,我们分11步合成了(+/-)-madindoline A和B。
