Two new cardenolide glycosides from Biondia hemsleyana

open access: yes, 2002
Two new cardenolide glycosides, biondianosides A and B, were isolated from the roots of endemic plant of Biondia hemsleyana (Warb.) Tsiang. Their structures were elucidated as periplogenin-3-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glycopyranosyl-(1- ->4 ...

Bioaccessibility, Intestinal Permeability and Plasma Stability of Isorhamnetin Glycosides from Opuntia ficus-indica (L.)

open access: yesInternational Journal of Molecular Sciences, 2017
Isorhamnetin glycosides are representative compounds of Opuntia ficus-indica that possess different biological activities. There is slight information about the changes in bioaccessibility induced by the glycosylation pattern of flavonoids, particularly ...

Protein hydrolysates in cell culture: Toward multi‐omics characterization

open access: yesBiotechnology Progress, EarlyView.
While protein hydrolysates are widely used in cell culture applications, they remain undefined and variable products. Multi‐omic characterization evaluating composition and function can transition hydrolysates toward semi‐defined media components.

Two new xanthone glycosides from Swertia tetraptera

open access: yes, 2001
Two new xanthone glycosides, tetraswerosides A and B, were isolated from the whole plant of Swertia tertraptera. Their structures were determined as 3-O-beta -D-glucopyranosyl-1-hydroxy-4,7-dimethoxyxanthone and 3-O-[beta -D-xylopyranosyl-(1-->6)-beta -D-

2-Deoxy-2-iodo-α-mannopyranosyl and -talopyranosyl Acetates:  Highly Stereoselective Glycosyl Donors for the Synthesis of 2-Deoxy-α-glycosides

open access: yes, 2016
TMS-OTf- or TBS-OTf-promoted glycosidation reactions of 2-deoxy-2-iodo-α-mannopyranosyl acetates 8−10 and the 2-deoxy-2-iodo-α-talopyranosyl acetate 11 provide the corresponding 2-deoxy-2-iodo-α-pyranosides, precursors to 2-deoxy-α-glycosides, as the ...

Synthesis and Glycosidase Inhibition Studies of Novel Exoglycals Targeting GH3 Family Enzymes: Insights from Comparative Analysis with Macrolide Antibiotics

open access: yesChemistry – A European Journal, EarlyView.
A series of structurally diverse exoglycals was synthesized using a modified Julia‐olefination approach from sugar‐derived precursors. These glycosidase transition‐state mimics were further diversified via CuAAC chemistry to yield triazole‐conjugated analogues.

Studies of iridoid glycosides using liquid chromatography/electrospray ionization tandem mass spectrometry

open access: yes, 2007
Fragmentation pathways of five iridoid glycosides have been studied by using electrospray ionization multi-stage tandem mass spectrometry (ESI-MSn). The first-stage MS data of the five iridoid glycosides were compared.

Four new pregnane glycosides from the stems of Marsdenia tenacissima

open access: yes, 2006
Four new pregnane glycosides, tenacigenosides A-D (1-4), along with six known pregnane aglycones and five known pregnane glycosides, were isolated from the stems of Marsdenia tenacissima (ROXB.) WIGHT et ARN. (Asclepiadaceae).
