RIBONUCLEOSIDES AND RNA

Annual Review of Biochemistry, 1995
Landmark discoveries such as the autocatalytic cleavage activity of certain RNA molecules, as well as small oligoribonucletide ribozymes and later the in vitro evolution of novel bioactive oligoribonucleotides (SELEX), have created entire new fields of biochemical research.

Distribution of purine ribonucleoside kinase and selectivet oxicity of 6-methylthiopurine ribonucleoside

Biochemical Pharmacology, 1968
Abstract 6-Methylthiopurine ribonucleoside (MMPR) and several other adenosine analogues have important antitumor properties. These must be converted to the nucleotide by a purine ribonucleoside kinase in order to be biologically active. MMPR is converted to the nucleotide by an enzyme indistinguishable from adenosine kinase.

Ribonucleosides as minor milk constituents

Zeitschrift für Ernährungswissenschaft, 1991
Ribonucleosides are minor milk constituents and show a typical pattern which is assumed to be species-specific. As well as the unmodified components adenosine, cytidine, guanosine, inosine, and uridine, modified compounds such as Nl-methyladenosine and N6-carbamoylthreonyladenosine--products of the transfer RNA catabolism--have been identified and ...

The metabolism of ribonucleoside by the human erythrocyte

Biochimica et Biophysica Acta (BBA) - General Subjects, 1968
Abstract 1. 1. Metabolic intermediates were isolated from erythrocytes after incubation of fresh or stored human blood for 2 h at 37° with inosine, inosine plus adenine or with adenosine. 2. 2. The metabolism of inosine or adenosien by fresh erythrocytes led to a large increase in the concentration of fructose diphosphate and triose phosphate

Reduction of Ribonucleosides to 2′‐Deoxyribonucleosides

Current Protocols in Nucleic Acid Chemistry, 2005
AbstractRibonucleosides are converted into 2′‐deoxyribonucleosides in good yields by a four‐step procedure. Selective protection of the 3′‐ and 5′‐hydroxyl groups with 1,3‐dichloro‐1,1,3,3‐tetraisopropyl‐1,3‐disiloxane is followed by functionalization of the 2′‐hydroxyl group with phenoxythiocarbonyl chloride.
