摘要:Provided herein is a simple, one-step, non-enzymatic synthesis of O-Acetyl-ADP-ribose (OAADPR) from NAD and sodium acetate in acetic acid. The extension of this reaction to other carboxylic acids, demonstrates that the reaction between NAD, and NAD analogs produces mixtures of the corresponding 2′- and 3′-carboxylic esters. Included are O-carboxyl-ADP-ribose compounds and corresponding methods of synthesis (e.g., O-propionyl-ADP-ribose, O-succinyl-ADP-ribose, O-malonyl-ADP-ribose), as well as non-adenosine nucleoside compounds.

摘要:A preparative enzymatic synthesis of hyaluronic acid (HA) from UDP-N-acetyl-D-glucosamine (UDP-GlcNAc) and UDP-glucuronic acid (UDP-GlcA) catalyzed by hyaluronic acid synthase is coupled with regeneration of the sugar nucleotides. Polymerizing UDP-GlcA and UDP-GlcNAc to form hyaluronic acid results in the formation of released UDP. The released UDP is, in turn, employed in the regeneration of UDP-GlcA and UDP-GlcNAc. Use of the released UDP for regenerating UDP-GlcA and UDP-GlcNAc prevents a build-up of these compounds and prevents or reduces feed back inhibition of the hyaluronic acid synthase reaction that would otherwise be caused by such build-up. Accordingly, the product yield is enhanced by the recycling of these compounds.

摘要:A process of regiospecific synthesis of N-9 purine nucleoside analogs in either solution or solid phase synthesis is described. The introduction of the sugar moiety or its analogue on to a 6-heteroarylium purine or its mesomeric betaine so that formation of only the N-9 position regioisomers of the purine nucleoside analogs (either D or L enantiomers) is obtained. This regiospecific introduction of the sugar moiety allows the synthesis of purine nucleoside analogs in high yields without formation of the N-7-positional regioisomers, while the 6-heteroaryliums are leaving groups facilitated for nucleophilic displacement. Solid supported 6-heterarylium purine bases can be used for purine based library synthesis and synthesis of nucleotide monophosphates and polyphosphates. Processes for providing novel 6-heteroarylium purines and their corresponding mesomeric betaines for the regiospecific synthesis of N-9 purine nucleoside analogs and nucleotides are described.
