Cyanohydrin glycosides of Passiflora: distribution pattern, a saturated cyclopentane derivative from P. guatemalensis, and formation of pseudocyanogenic alpha-hydroxyamides as isolation artefacts.
Nineteen species of Passiflora (Passifloraceae) were examined for the presence of cyanogenic glycosides. Passibiflorin, a bisglycoside containing the 6-deoxy-beta-D-gulopyranosyl residue, wasExpand
Polysaccharides from lichens: structural characteristics and biological activity.
TLDR
The current review summarizes present knowledge on the structural characteristics and biological activity of lichen polysaccrides. Expand
Rhamnopyranosylgalactofuranan, a new immunologically active polysaccharide from Thamnolia subuliformis.
TLDR
The immunomodulating activity of Ths-3 was tested in an in vitro phagocytosis assay and the classical anticomplementary assay, and proved to be active in both tests. Expand
Cyanohydrin glucosides of turneraceae
TLDR
This is the first report of linamarin from the Turneraceae, and both types of 1,4-dioxygenated cyclopentanes ( cis and trans ) were represented. Expand
Exopolysaccharides from Cyanobacterium aponinum from the Blue Lagoon in Iceland increase IL-10 secretion by human dendritic cells and their ability to reduce the IL-17+RORγt+/IL-10+FoxP3+ ratio in
TLDR
The study shows that EPSs secreted by C. aponinum stimulate DCs to produce vast amounts of the immunosuppressive cytokine IL-10, which may play a role in the beneficial clinical effect on psoriasis following bathing in the Blue Lagoon. Expand
Immunologically active (1→3)-(1→4)-α-D-Glucan from Cetraria islandica
Summary A polysaccharide, Ci-3, resembling isolichenan except with a much higher degree of polymerization, has been isolated from the water extract, as well as from the alkali extract, of the lichenExpand
Structural characterisation of a highly branched galactomannan from the lichen Peltigera canina by methylation analysis and NMR-spectroscopy
Abstract An alkali-extractable water-soluble polysaccharide, Pc-4, was isolated from the lichen Peltigera canina using ethanol fractionation and size exclusion chromatography. The average molecularExpand
Secondary metabolites from cetrarioid lichens: Chemotaxonomy, biological activities and pharmaceutical potential.
TLDR
While the ethnic uses of cetrarioid lichens and the pharmaceutical potential of their secondary metabolites have been recognized, the knowledge of a large number of lichen substances with interesting structures is still limited to various in vitro assays with insufficient biological annotations, and this area still deserves more research in bioactivity, drug targets and screening.

In vitro and in vivo immunomodulating effects of traditionally-prepared extract and purified compounds from Cetraria islandica
Cetraria islandica has been used for centuries in folk medicine in many countries to treat a number of conditions, mainly as an aqueous extract. C. islandica contains many compounds, some of whichExpand
Marchantin A, a macrocyclic bisbibenzyl ether, isolated from the liverwort Marchantia polymorpha, inhibits protozoal growth in vitro.
TLDR
In vitro anti-plasmodial activity-guided fractionation of a diethyl ether extract of the liverwort species Marchantia polymorpha led to isolation of the bisbibenzyl ether, marchantin A, which showed inhibitory effects against Plasmodium falciparum and other protozoan species in vitro. Expand
