New triterpenoid saponin glycosides from the fruit fibers of Trichosanthes cucumerina L

Five new triterpenoid saponin glycosides, trichocucumerisides A-E (1-5), together with eleven known compounds (6-16) were isolated from fruit fibers. The structures of the new compounds were elucidated by detailed analysis of NMR and mass spectroscopic data as well as chemical reactions. The anti-in...

Description
Summary:Five new triterpenoid saponin glycosides, trichocucumerisides A-E (1-5), together with eleven known compounds (6-16) were isolated from fruit fibers. The structures of the new compounds were elucidated by detailed analysis of NMR and mass spectroscopic data as well as chemical reactions. The anti-inflammatory study against nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 cells shows that compounds 7 and 9 exhibited stronger NO inhibitory activity, with IC values of 3.0 and 2.7 μM, respectively, with comparison to positive references Celecoxib and aminoguanidine (IC values 75.7 and 75.0 μM, respectively). Compounds 7 and 9 also possessed a greater selectivity index (SI) of approximately 3-4-fold activity than that of the positive references.
