Anticancer Activity of Sea Cucumber Triterpene Glycosides
Triterpene glycosides are characteristic secondary metabolites of sea cucumbers (Holothurioidea, Echinodermata). They have hemolytic, cytotoxic, antifungal, and other biological activities caused by membranotropic action. These natural products suppress the proliferation of various human tumor cell lines in vitro and, more importantly, intraperitoneal administration in rodents of solutions of s...
متن کاملFour new triterpene glycosides from Thalictrum squarrosum.
Four new triterpene glycosides were isolated from the dried aerial parts of Thalictrum squarrosum (Ranunculaceae). They were designated as squarroside I, being a cycloartane-type glycoside, and squarrosides II, III and IV, being oleanene-type glycosides. Their structures were established by using two dimensional (2D) NMR techniques.
متن کاملFive triterpene glycosides from Oxytropis myriophylla.
Four new triterpene glycosides: one cycloartane-type glycoside and three azukisapogenol glycosides were isolated together with one known oleanene bisdesmoside from the Mongolian natural medicine, Oxytropis myriophylla.
متن کاملTriterpene glycosides and glucosyl esters, and a triterpene from the leaves of Schefflera actinophylla.
From the EtOAc and 1-BuOH fractions, three new ursane-type and four new lupane-type triterpenes, along with nine known glycosides and glycosyl esters of lupane-type were isolated from the leaves of Schefflera actinophylla. All the isolated compounds were obtained for the first time from this plant. The structures of the new triterpenes were determined through a combination of spectroscopic and ...
متن کاملSweet and sweetness-inducing activities of new triterpene glycosides, strogins.
In a previous study we isolated homologues of new oleanane-type triterpene glycosides from leaves of Staurogyne merguensis Kuntze and named them strogins. Strogins themselves have a sweet taste (sweet activity), which diminishes in a few minutes. Subsequent application of cold water to the mouth then elicits a sweet taste (sweetness-inducing activity). In the present study we systematically exa...
