Protection of 2′‐Hydroxy Functions of Ribonucleosides [PDF]

open access: yesCurrent Protocols in Nucleic Acid Chemistry, 2000
AbstractThe main purpose of this article is to discuss 2′‐protection in the context of effective oligoribonucleotide synthesis. Emphasis is placed on the 2′‐protecting groups of choice in the synthesis of oligo‐and polyribonucleotides, and the requirements that a protective group must satisfy to become the 2′‐hydroxyl‐protecting group of choice ...

Characterization of nucleoside transport in the intestinal protozoan parasite Giardia intestinalis. [PDF]

open access: yes, 1994
A rapid sampling technique has been adapted and used to measure nucleoside transport in a human-derived isolate of the intestinal protozoan parasite Giardia intestinalis (syn. G.

Dynamic tRNA and rRNA modificome changes upon oxidative stress [PDF]

open access: yes, 2021
Post-transcriptional modifications (PTMs) in RNA are present in all known RNA species and conserved in all kingdoms of life. Transfer RNA (tRNA) has been shown to have numerous conserved modifications, which exemplifies the importance of modifications ...

Novel approach to Synthesis of Pentofurano nucleoside assisted natural phosphate doped with CF3SO3H as catalyst [PDF]

open access: yes, 2013
This article describes a method for the preparation of ribonucleosides using the solid-phase approach. Several D-ribonucleosides are prepared from 1-O-acetyl-2,3,5-tri-O-benzoyl-?-D-ribofuranoside and trimethylsilylated nucleobases under mild conditions ...

Abiotic Ribonucleoside Formation in Aqueous Microdroplets: Mechanistic Exploration, Acidity, and Electric Field Effects

open access: yesChemistryEurope
Aqueous microdroplets have been reported to dramatically increase the rate of chemical reactions. Proposed mechanisms for this acceleration include confinement effects upon droplet evaporation, and Brønsted acid or electric field catalysis at the air ...
