Chromanones with leishmanicidal activity from Calea uniflora.
The dichloromethane extract of Calea uniflora afforded a mixture of two novel chromanones, uniflorol-A (1) and uniflorol-B (2), and one known chromanone, 2,2-dimethyl-6-(1-hydroxyethyl)-chroman-4-one (3). The structures of these compounds were determined by spectroscopic methods. Biological activity of the compounds against Leishmania major promastigotes was evaluated. Mixture of the novel chro...
متن کاملNew pregnane glycosides from Cynanchum ascyrifolium.
Two new pregnane glycosides, cynascyrosides D and E, were isolated from the roots of Cynanchum ascyrifolium. The structures of these compounds were determined on the basis of spectroscopic and chemical evidence as cynajapogenin A 3-O-alpha-L-cymaropyranosyl-(1-->4)-beta-D-digitoxopyranosyl-(1-->4)-beta-L-cymaropyranoside and cynajapogenin A 3-O-beta-D-glucopyranosyl-(1-->4)-alpha-L-diginopyrano...
متن کاملInsecticidal Constituents and Activity of Alkaloids from Cynanchum mongolicum.
Based on MS and NMR data and bioassay-guided tracing, three insecticidal alkaloids I, II and III from Cynanchum mongolicum were identified to be antofine N-oxide, antofine and tylophorine. Alkaloid I was more toxic than alkaloids II and III, but they were less active against Spodoptera litura than total alkaloids. The contact toxicity from these alkaloids against the aphid Lipaphis erysimi was ...
متن کاملThree new steroidal glycosides from the roots of Cynanchum auriculatum.
Three new steroidal glycosides, cyanoauriculosides F, G and H (1-3), were isolated from the roots of Cynanchum auriculatum (Asclepiadaceae) along with two known steroidal derivatives. On the basis of spectroscopic analysis and chemical methods, their structures were identified as 20-O-acetyl-8,14-seco-penupogenin-8-one 3-O-α-L-cymaropyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-α-L-diginopyranosyl-...
متن کاملC21 steroidal glycosides from the roots of Cynanchum paniculatum.
As a part of our continuing research for bioactive constituents from Cynanchum plants, four new C21 steroidal glycosides, cynapanoside D-G (1-4), together with six known compounds (5-10) were isolated from the roots of Cynanchum paniculatum (Bge.) Kitag. Their structures were elucidated on the basis of 1D- and 2D-NMR spectroscopic data as well as HR-ESI-MS analysis. Compound 8 exhibited potent ...
