Marine diterpene glycosides

Bioorganic & Medicinal Chemistry, 2011
Marine diterpene glycosides (MDGs) respresent a small but highly significant group of the much larger class of marine diterpenes. The three well-studied examples of MDGs are eleutherobins, pseudopterosins and fuscosides, all of which exhibit extremely promising biological activity.

Diterpene glycosides from Iphiona aucheri

Phytochemistry, 1994
Iphiona aucheri is responsible for poisoning racing camels (Camelus dromedarius) in the United Arab Emirates U. A. E. Terpenoids, a non-toxic pyrrolizidine alkaloid and two diterpene glycosides, atractyloside and carboxyatractyloside, were isolated and their structures determined by spectroscopic methods.

Diterpene glycosides from Gutierrezia sphaerocephala

Phytochemistry, 1986
Abstract Five new diterpene glycosides, two arabinopyranosides and three xylopyranosides were isolated from Gutierrezia sphaerocephala . One of the arabinosides contained a tiglate ester at the 3′-position of the sugar moiety.

Hypoxylonoids A−G: Isopimarane diterpene glycosides from Xylaria hypoxylon

Phytochemistry, 2021
Seven undescribed isopimarane diterpene glycosides hypoxylonoids A-G, along with five known analogues were obtained from the fungus Xylaria hypoxylon. The structures and absolute configurations of hypoxylonoids A-G were confirmed by extensive spectroscopic and single-crystal X-ray diffraction analyses. Among these compounds, the γ-lactone moiety formed

Diterpene and diterpene glycosides from Rabdosia eriocalyx

Phytochemistry, 1989
Abstract An ent -kaurene diterpenoid, maoecrystal K, and its β-glucopyranoside, rabdoside 1, as well as a minor diterpene glycoside, rabdoside 2 were isolated from Rabdosia eriocalyx . The structures of the three compounds were determined by their spectral properties and chemical transformations.

Synthesis of diterpene glycosides

Monatshefte f�r Chemie Chemical Monthly, 1997
Mono-, di-, and linear triglycosides of a diterpene alcohol, derived from abietic acid and glucose have been synthesized employing peracetylbromo-α-D-glucose (4) and maltose derivatives5 and8 as glycosyl donors. The triglycoside14 exhibits slight haemolytic activity.

Diterpene Glycosides fromEgletes viscosa

Planta Medica, 2005
A phytochemical investigation of the CHCl (3)-soluble extract of the entire plant of Egletes viscosa (Asteraceae), collected in Peru, afforded two new labdane glycosides, 13-hydroxy-7-oxolabda-8,14-diene 13( R)- O-alpha- L-arabinopyranoside and 13-hydroxylabda-7,14-diene 13( R)- O-alpha- L-arabinopyranoside, along with four known compounds.
