Chemical synthesis and isolation of UDP-2-deoxy glucose and galactose

2-Deoxy sugars are attractive compounds in synthetic chemistry with regard to reactivity and stereoselectivity. Moreover, their ability to inhibit enzymes and metabolism is significant in biology. In this study, uridine-5′-diphosphate (UDP)-2-deoxy glucose (11) and galactose (12) were synthesized chemically. These sugar donors for glycosyltransferases were obtained α-selectively via phosphorylation using thioglycosides, coupling reaction with uridine-5′-monophosphate (UMP)-morpholidate, and moderate deacetylation. Isolation was carried out by sequential silica-gel chromatography using two kinds of developing solvents in a refrigerator. The structures were elucidated from the NMR results. Investigation of stability showed that the synthesized UDP-2-deoxy sugars were hydrolyzed much faster in buffer (pH 4) than the natural UDP sugars.

A Simple synthesis of sugar nucleoside diphosphates by chemical coupling in water

Sugar nucleotides made easy: The new reagent ImIm , which is formed in-situ in water, is shown to activate nucleoside 5'-phosphates to their imidazolides, these can subsequently couple with sugar-1-phosphates; the whole procedure takes place in water. This truly simple method yields a crude product mixture that can be used directly as a source of donors for glycosyltransferase- mediated oligsaccharide synthesis. In the scheme, B stands for the nucleobases U, A, or G. Copyright

Optimization of UDP-N-acetylmuramic acid synthesis

UDP-N-acetylmuramic acid (UDP-MurNAc) is a substrate of MurC, an important enzyme in the intracellular pathway of bacterial peptidoglycan biosynthesis. Various approaches towards preparation of UDP-Mur/VAc have been published but these synthetic preparations were shown to include many problematic steps. An optimization study with the focus on muramyl phosphate and UMP-morpholidate coupling was performed, resulting in a synthetic procedure enabling robust and easily reproducible production on a multi-gram scale.

Multi gram synthesis of UDP-N-acetylmuramic acid

As part of an effort to discover novel antibacterial agents, a new and efficient synthesis was established in order to provide a large amount of UDP-N-acetylmuramic acid (UDP-MurNAc).
