Transglycosylation Reactions of 6-Thioguanine Acyclonucleosides

Nucleosides, Nucleotides and Nucleic Acids, 2000
9-(2-Acetoxyethoxy)methyl-N2-acetyl-6-thoguanine (2) undergoes two different transglycosylation reactions: i) the 79 isomerization, which gives the respective 7-regioisomer (3) as the major product, ii) the 9S6 glycosyl migration, which leads to a 9,S6-disubstituted product (4). S6-Methylation completely stopped the reversibility of transglycosylation.

Benzimidazoles in the Reaction of Enzymatic Transglycosylation

Nucleosides, Nucleotides and Nucleic Acids, 1995
Abstract Substrate activity of a broad spectrum of derivatives of benzimidazole in the reaction of enzymatic ribo- and 2-deoxyribosylation catalyzed by purine nucleoside phosphorylase of whole cells of E. coli BMT-1D/1A has been studied. Guanosine or 2′-deoxyguanosine were used as glycosyl donors.

Enzymatic transglycosylation

2009
The most important functions of carbohydrates are structural roles and energy storage, but carbohydrate parts of glycoproteins and glycolipids are involved in biological functions mainly related to cell recognition events. Carbohydrates are also important molecules in the technological domain.

[Transglycosylation of L-ascorbic acid].

Prikladnaia biokhimiia i mikrobiologiia, 2007
Cyclodextrin glucanotransferases (CGTase, EC 2.4.1.19) produced by mesophilic, thermophilic, and halophilic bacilli, as well as maltase (EC 3.2.1.20) produced by various strains of Saccharomyces cerevisiae have been applied for transglycosylation of L-ascorbic acid using starch, maltodextrin, gamma-cyclodextrin, and maltose as donors of glucosyl ...

Transglycosylation Reaction of 6-Thioguanosine

Nucleosides and Nucleotides, 1999
Abstract Peracetylated 6-thioguanosine (2) undergoes the so far unknown N→S transglycosylation reaction to form a stable 9,S6 -bis(ribosyl) derivative (3) and N2-acetyl-6-thioguanine (4). The reaction takes place at elevated temperatures with no catalyst, or in solution in the presence of acidic catalysts.

[Transglycosylation of benzo[h]quinazolines].

Prikladnaia biokhimiia i mikrobiologiia, 2009
This was the first study to apply cyclodextrin glucanotransferases (CGTase, EC 2.4.1.19) produced by mesophilic, thermophilic, alkaliphilic, and halophilic bacilli as well as pullulanase, beta-amylase, beta-galactosidase, and beta-fructofuranosidase for transglycosylation of benzo[h]quinazolines.
