  Some new derivatives of glycyrrhetic acid and oleanolic acid were prepared and characterized. Various combinations of the modified and normal functional groups were synthesized as required for a separate study of the uncoupling activities of glycyrrhetic acid and oleanolic acid. The hydroxyl functions of these two acids were modified to β-carboxypropionyl, acetyl and β-methoxycarbonylpropionyl esters. The carboxyl function of glycyrrhetic acid was converted to amide, p-amidobenzoic acid, o-amidobenzoic acid and the glycine conjugate of the acid. 11-Deoxy (glycyrrhetic acid) and 9,11-dehydro-11-deoxo (from both acids) analogues were prepared. 11-Oxo analogues of oleanolic acid were synthesized as well as the methyl esters.

  摘要：制备和表征了一些甘草酸和齐墩果酸的新衍生物。根据需要合成了修改和正常官能团的各种组合，以便对甘草酸和齐墩果酸的解耦活性进行单独研究。这两种酸的羟基功能被修改为β-羧丙酰基、乙酰基和β-甲氧羰基丙酰酯。甘草酸的羧基功能转化为酰胺、对-氨基苯甲酸、邻-氨基苯甲酸和该酸的甘氨酸结合物。制备了11-去氧（甘草酸）和9,11-脱氢-11-去氧（来自两种酸）的类似物。合成了齐墩果酸的11-酮类似物以及甲酯。

  Two triterpenoid–peptide conjugates containing oleanolic acid and glycyrrhetinic acid were synthesized and the properties of self-assembly into organogels were studied systematically. The results showed that the xerogels could selectively adsorb dyes from water and it could be utilized in water purification by removing toxic dyes. In addition, the formation of supramolecular gels was associated to basicity increase by employing pH-indicator dyes in water.

  研究人员合成了含有齐墩果酸和甘草次酸的两种三萜肽共轭物，并对其自组装成有机凝胶的特性进行了系统研究。结果表明，异构凝胶能选择性地吸附水中的染料，可用于水净化，去除有毒染料。此外，通过在水中使用 pH 指示剂染料，超分子凝胶的形成与碱性增加有关。
