日期:——
An intramolecular nucleosidation approach provides easy access to orotidine in high yields. Notably, orotate itself is used as a leaving group at the anomeric position. This method has the potential for facileaccess to derivatives of orotidine of therapeutic interest, with implications for prebiotic formation of nucleosides.

The efficient synthesis of O-β-D-ribofuranosyl-(1″2′)-guanosine-5″-O-phosphate and O-β-D-ribofuranosyl-(1″2′)-adenosine-5″-O-phosphate, minor tRNA components, have been developed, and their conformational properties were examined by NMR spectroscopy.
Provided herein are stereoisomerically pure ester and carbonate analogues of nicotinamide riboside and nicotinamide riboside hydride, and pharmaceutical compositions and uses thereof. The stereoisomerically pure ester and carbonate analogues of nicotinamide riboside and nicotinamide riboside hydride may be used to treat a disease or disorder that would benefit from increased NAD levels including a mitochondrial disease or disorder, insulin resistance, a metabolic syndrome, diabetes, obesity, for increasing insulin sensitivity in a subject, or to treat or prevent a skin condition.
The compounds have general formulas (I) or (II):
wherein R1 is —C(═O)—X—(C2-C18 straight chain or branched) alkyl or —C(═O)—X—(C2-C18 straight chain or branched) alkenyl; each R2 is independently selected from hydrogen, and a —C(O)—X—(C1-C18 straight chain or branched) alkyl or a —C(O)—X—(C2-C18 straight chain or branched) alkenyl; and X is a covalent bond or O.
