摘要

从 Lindera glauca（林达草）的根中分离出了三种新的酯类化合物 glasesterterpenoids A-C（1-3），它们具有前所未有的 7-Cyclohexyldecahydronaphthalene 碳骨架。通过量子化学计算和光谱方法阐明了它们的结构。提出了 1-3 的生物发生途径。在生物测定中，与阳性对照喜树碱相比，glasesterpenoid C 具有 DNA 拓扑异构酶 1（Top1）抑制活性。这些发现代表了从鳞茎草根中首次发现具有 7-环己基十氢萘碳骨架的酯类化合物。

Glasesterterpenoids A−C: three sesterterpenoids with 7-cyclohexyldecahydronaphthalene carbon skeleton isolated from the root of Lindera glauca

Three novel sesterterpenoids glasesterterpenoids A−C (1−3), featuring an unprecedented 7-cyclohexyldecahydronaphthalene carbon skeleton, were isolated from the root of Lindera glauca (L. glauca). Their structures were elucidated by quantum chemical calculations and spectroscopic methods. The biogenetic pathway for 1−3 is proposed. In the bioassay, glasesterterpenoid C exhibited DNA topoisomerase 1 (Top1) inhibitory activity compared with the positive control, camptothecin. These findings represent the first examples of sesterterpenoids with a 7-cyclohexyldecahydronaphthalene carbon skeleton from the root of L. glauca.
