definition
An organic molecule in which a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or a single-ringed pyrimidine, is covalently attached to a five-carbon pentose sugar (deoxyribose in DNA or ribose in RNA). When the phosphate group is covalently attached to the pentose sugar, it forms a nucleotide.
Pharmacologic treatment for herpesvirus infections has targeted the virus-specific enzyme, thymidine kinase (TK ), with nucleoside analogs.
This medicine contains the active ingredient emtricitabine, which is a type of medicine called a nucleoside reverse transcriptase inhibitor.
Attached to the other side of the sugar is a phosphoric acid unit, linking the nucleoside to the neighboring sugar.
However, the unsubstituted nucleosides could lightly yield the fragment ions of the nucleoside base and sugar ring.
The phosphorylation of purine nucleosides to form nucleotides by nucleoside kinase is an alternative pathway of purine salvage.
Chiroscience has made a series of medicines called purine nucleoside phosphorylase (PNP) inhibitors which have shown promise in animal models of arthritis.
The phosphorylation of purine nucleosides to form nucleotides by nucleoside kinase is an alternative pathway of purine nucleosides to form nucleotides by nucleoside kinase is an alternative pathway of purine salvage.
These are all drugs known as nucleoside analogs, nucleoside reverse transcriptase inhibitors (NRTIs ).
