Abstract

Three new diterpene esters with a myrsinol-type skeleton have been isolated from Euphorbia decipiens BOISS. & BUHSE. The structure elucidation of the isolated compounds was based primarily on two-dimensional (2D)-NMR techniques including correlation spectroscopy (COSY), heteronuclear multiple quantum coherence (HMQC), heteronuclear multiple bond correlation (HMBC) and nuclear Overhauser effect spectroscopy (NOESY) experiments. Compounds 1 and 3 are active against prolyl endopeptidase and compound 2 showed inhibitory activity against urease enzyme.

摘要

从拟大戟（Euphorbia decipiens BOISS. & BUHSE.）中分离出了三种具有肉豆蔻醇型骨架的新型二萜酯。所分离化合物的结构解析主要基于二维（2D）-核磁共振技术，包括相关光谱法（COSY）、异核多量子相干（HMQC）、异核多键相关（HMBC）和核Overhauser效应光谱（NOESY）实验。化合物1和3对脯氨酰内肽酶有活性，化合物2对脲酶显示出抑制活性。
