A variety of metabolic intermediates of the glycolytic pathway and tricarboxylic acid cycle have been found to be inhibitors of 6-phosphogluconate dehydrogenase isolated from sheep liver. All nucleoside 5’-triphosphates and 5’diphosphates are inhibitors with Ki values averaging 0.8 mM, nucleoside 5’-monophosphates are also inhibitory with Ki values averaging 6 mu. The 2’and 3’monophosphates of ...

We have developed a synthetic route for the preparation of a hybrid bisubstrate small molecule based on a nucleoside. A prototype compound was designed and docked into the catalytic domain of the AdSS enzyme bridging the region between the magnesium center of the protein to the nucleoside region. The synthesis involves coupling a brominated peptide fragment capable of complexing magnesium to a ...

The method of conjugation of a nucleoside or related compound to a carrier protein may have a significant effect on the specificity of the antibodies elicited. It is demonstrated, by means of the membrane-filtration assay, that anti-isopentenyladenosine antibodies produced by the 'periodate procedure' are much more reactive with the periodateoxidized form of the nucleoside than with the parent ...

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has developed into an unprecedented global pandemic. Nucleoside analogs, such as Remdesivir and Favipiravir, can serve the first-line broad-spectrum antiviral drugs by targeting viral polymerases. However, underlying mechanisms for efficacies these are far from well understood. Here, we reveal that a pyrazine derivativ...

A rigid molecular clip comprising bisphosphonate binding sites and aromatic sidewalls forming an electron-rich cavity is able to distinguish between nucleosides and nucleotides in aqueous solution. Neutral nucleosides as well as antibiotics derived thereof are drawn into the unpolar interior of the cleft and lead to substantial upfield-shifts in the H NMR spectrum. Nucleoside drugs can therefor...

An easy and efficient strategy to obtain libraries of 5'-phosphodiester and 5'-phosphoramidate monoester nucleoside analogues in a highly pure form has been developed, starting from a new nucleoside based solid support. The nucleoside scaffold has been anchored through a 5'-phosphodiester linkage to Tentagel HL resin, functionalized with a 3-chloro-4-hydroxyphenylacetic linker. The solid phase ...

[structure: see text] The alpha-l-threofuranosyl nucleoside triphosphates of T, G, and D (tTTP, tGTP, and tDTP) were synthesized from the described 2'-O-DMT-protected derivatives using the Eckstein method, while the corresponding C derivative (tCTP) was prepared from the 2'-O-acetyl derivative. The prepared alpha-l-threofuranosyl nucleoside triphosphates, despite being one carbon shorter than t...
