Phosphorylation of uridine and cytidine by uridine–cytidine kinase
Journal of Biotechnology, 2014Uridine 5'-monophosphate (5'-UMP) and cytidine 5'-monophosphate (5'-CMP) were biosynthesized by recombinant uridine-cytidine kinase (UCK) and acetate kinase (ACK). The ack and uck genes from Escherichia coli K12 and the uck1, uck2 and ack genes from Lactobacillus bulgaricus ATCC 11842 were cloned and inserted into the plasmid pET-28a.

Solvolyses of Cytosine and Cytidine
Journal of Pharmaceutical Sciences, 1972It has been confirmed by UV spectrophotometry and TLC that cytosine and cytidine deaminate to uracil and uridine, respectively, at all pH values. These products slowly degrade further in strongly alkaline solutions. Cytidine also undergoes a parallel degradation in strongly alkaline solutions to a nonchromophoric compound, which can be assigned to a ...

AbstractThe large change in the electronic absorption spectrum of cytidine on going from an aqueous to an aprotic medium is attributed to the existence of a hydrogen bonded solvent‐solute complex in solvents capable of donating a proton. The spectrum of cytidine in a variety of solvents and the spectra of a number of nontautomerising model compounds ...

Abstract A practical, seven-step synthesis of 5-(β- d -ribofuranosyl)cytosine ( 1 , ψ-cytidine) was achieved. ψ-Uridine was converted into the 2′,3′-isopropylidene acetal 2 in 85% yield. Tosylation of 2 to the 5′-sulfonate 3 , followed by deacetonation, afforded 5′- O -tosyl-ψ-uridine ( 6 ) in good yield.
