beta- and gamma-Hydroxynitrile glucosides are structurally related to cyanogenic glucosides (alpha-hydroxynitrile glucosides) but do not give rise to hydrogen cyanide release upon hydrolysis. Structural similarities and frequent co-occurrence suggest that the biosynthetic pathways for these compounds share common features. Based on available literature

Production of zearalenone-4-glucoside, a-zearalenol-4-glucoside and ß-zearalenol-4-glucoside
Mycotoxin Research, 2007The work at hand describes the production of the zearalenone (ZON) metabolites zearalenone-4-glucoside (ZON-4G), a-zearalenol-4-glucoside (oc-ZOL-4G) and ß-zearalenol-4-glucoside (ß-ZOL-4G). In a first step a genetically modified yeast strain, expressing theArabidopsis thaliana UDP-glu-cosyltransferase UGT73C6, was treated with ZON to produce ZON-4G ...

Microbial glucosidation of dihydroxyanthraquinones. General properties of the glucosidation system
Folia Microbiologica, 1974Corresponding mono-β-d-glucosides were obtained by fermentation ofStreptomyces aureofaciens B 96 with four isomeric dihydroxyanthraquinones (alizarin, quinizarin, chrysazin and anthraflavin). The effect of some factors (sugar source, concentration of substrates, pH) on biosynthesis of 1-hydroxy-2-(β-d-glucopyranosyloxy)anthraquinone was studied and ...

Generation of primary amide glucosides from cyanogenic glucosides
Phytochemistry, 2009The cyanogenic glucoside-related compound prunasinamide, (2R)-beta-d-glucopyranosyloxyacetamide, has been detected in dried, but not in fresh leaves of the prunasin-containing species Olinia ventosa, Prunus laurocerasus, Pteridium aquilinium and Holocalyx balansae. Experiments with leaves of O.

Berichte der deutschen chemischen Gesellschaft, 1909
Wahrend die Aldosen bei Gegenwart von starker Salzsaure leicht zwei Molekule Athylmercaptan fixieren unter Bildung von schon krystallisie-renden Mercaptalen, sind die den synthetischen Glucosiden entsprechenden Thio-Verbindungen noch unbekannt. Da aber schwefelhaltige Glucoside im Pflanzenreich haufig vorkommen, so bietet die Kenntnis der einfachsten ...

Pharmacology & Therapeutics, 1990
A number of studies have shown that drug glucosidation occurs in vertebrates. This review summarizes information on the chemical, physical and biological properties of eleven drug glucosides. Three out of two hundred individuals exhibited a complete lack of amobarbital-N-glucoside formation. The data from a pair of identical twins who were deficient in

Pyrimidinylmethylphenyl glucoside as novel C-aryl glucoside SGLT2 inhibitors
Bioorganic & Medicinal Chemistry Letters, 2010Novel C-aryl glucoside SGLT2 inhibitors containing pyrimidine motif were designed and synthesized for biological evaluation. Among the compounds assayed, pyrimidine containing methylthio moiety 11 g demonstrated the best in vitro inhibitory activity against SGLT2 in this series to date (IC(50)=10.7 nM).

Synthese einiger Glucoside [PDF]
Berichte der deutschen chemischen Gesellschaft, 1909 Fur die kunstliche Bereitung der Glucoside sind zwei Methoden bekannt. Die erste, von Michael gefundene beruht auf der Wechselwirkung zwischen Phenol und Acetochlorglucose in alkalisch-alkoholischer Losung. Bei der zweiten werden Zucker und Alkohole durch die Wirkung von Salzsaure vereinigt.
