Two Unusual Methylidenecyclopropane Glucosides from Metaxya rostrata C.Presl
Two new natural compounds, (1R,2E)-2-(6-hydroxyhexylidene)cyclopropyl-β-D-glucopyranoside (1) and (6E)-6-[(2R)-2-(β-D-glucopyranosyloxy)cyclopropylidene]hexanoic acid (2), glucosides of a very rare methylidenecyclopropane alcohol, as well as two known glycosides of phenolic acids, namely 4-O-β-D-glucopyranosylcaffeic acid (3) and (E)-4-O-β-D-glucopyranosylcoumaric acid (4), and methyl α-fructof...
متن کامل2-Deprenyl-Rheediaxanthone B Isolated from Metaxya rostrata Induces Active Cell Death in Colorectal Tumor Cells
Metaxya rostrata C. Presl (Metaxyaceae) is a common tree fern in Central and South America that is used for the treatment of intestinal ulcers and tumours in ethnic medicine. Using a bioactivity-guided strategy 2-deprenyl-rheediaxanthone B (XB) has been isolated as one of the active principles in this plant. XB induced loss of cell viability in colorectal cancer cell lines at IC50 concentration...
متن کاملTwo new phenolic glucosides from Lagerstroemia speciosa.
Two new phenolic glucosides, 1-O-benzyl-6-O-E-caffeoyl-β-d-glucopyranoside and 1-O-(7S,8R)-guaiacylglycerol-(6-O-E-caffeoyl)-β-d-glucopyranoside, were isolated from the aerial parts of Lagerstroemia speciosa, along with ten known compounds. The structures of the isolated compounds were determined based on 1D- and 2D-NMR, Q-TOF MS and optical rotation spectroscopic data. All of the compounds sho...
متن کاملTwo new podophyllotoxin glucosides from Sinopodophyllum emodi (Wall.) Ying.
Two new aryltetralin-type lignans, isopodophyllotoxin 7'-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside (1) and 4-demethyl-picropodophyllotoxin 7'-O-beta-D-glucopyranoside (2), along with eight known podophyllotoxin derivatives: 4-demethyl-podophyllotoxin 7'-O-beta-D-glucopyranoside (3), podophyllotoxin 7'-O-beta-D-glucopyranoside (4), deoxypodophyllotoxin (5), picropodophyllotoxin (6),...
متن کاملTwo new cyanogenic glucosides from the leaves of Hydrangea macrophylla.
Chemical investigation of the ethanol extract of the aerial parts of Hydrangea macrophylla collected in the Sichuan Province of China resulted in the isolation of two new cyanogenic glucosides. Their structures were elucidated as [(2R)-2-β-D-glucopyranosyloxy)-2-(3,4-dimethoxy-phenyl)] acetonitrile (1) and {(2R)-2-[α-D-glucopyranosyl(1-->6)β-D-glucopyranosyloxy]-2-(3-hydroxy-4-methoxy-phenyl)}a...
