A Glycosynthase Catalyst for the Synthesis of Flavonoid Glycosides
Angewandte Chemie International Edition, 2007 Glycosylation of lipophilic small molecules is one of the predominant strategies by which the bioactivity of these compounds is modulated in living organisms. Indeed, even simple plants, such as Arabidopsis thaliana, dedicate over 120 open reading frames encoding many activated sugar-dependent glycosyltransferases to this task alone.

Substrate Selectivities of GH78 α-L-Rhamnosidases from Human Gut Bacteria on Dietary Flavonoid Glycosides. [PDF]
Moleculesα-L-rhamnosidases play a key role in the metabolism and biodegradation of dietary flavonoid glycosides. We have developed a novel microplate spectrophotometric method to rapidly evaluate the conversion rates and substrate selectivities of ...

New Flavonoid Glycosides and Cyanogenic Glycosides from Dracocephalum peregrinum
Chemical and Pharmaceutical Bulletin, 2009 Separation of ethyl acetate fractionation of Dracocephalum peregrinum afforded three new flavonoid glucosides (1-3), and a new cyanogenic glucoside (4). Their structures were elucidated based on HR-electron spray ionization (ESI)-MS, EI-MS, UV, IR, 1D-, and 2D-NMR data. 1-4 were tested in vitro for their antiinflammatory activity against the RAW 264.7,
