Stolonidiol, a marine natural product, has been reported to potentiate the activity of choline acetyltransferase (ChAT), the enzyme that produces the neurotransmitter acetylcholine. Here we report the total synthesis of stolonidiol starting from (R)-(+)-limonene. To identify the mechanism by which ChAT activity is increased, we sought to identify the biological target of stolonidiol. We show that stolonidiol
据报道,Stolonidiol 是一种海洋天然产物,可增强胆碱乙酰转移酶 (ChAT) 的活性,该酶可产生神经递质乙酰胆碱。在这里,我们报告了从 (R)-(+)-柠檬烯开始的 stolonidiol 的全合成。为了确定 ChAT 活性增加的机制,我们试图确定 stolonidiol 的生物学靶点。我们表明,stolonidiol 与蛋白激酶 C (PKC) 的佛波酯结合位点结合,诱导 PKC 易位到细胞膜,并激活激酶活性。此外,我们证实了在用 stolonidiol 处理细胞后观察到的 ChAT 活性增加,并表明这种作用是由 PKC 介导的。总的来说,我们的数据强烈表明,stolonidiol 激活 PKC 是导致 ChAT 活性增强的原因。
