Cytidine is a nucleoside molecule that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) via a β-N1-glycosidic bond. Cytidine is a component of RNA.
If cytosine is attached to a deoxyribose ring, it is known as a deoxycytidine.
Dietary sources of cytidine include foods with high RNA (ribonucleic acid) content,[1] such as organ meats, Brewer's yeast, as well as pyrimidine-rich foods such as beer. During digestion, RNA-rich foods are broken-down into ribosyl pyrimidines (cytidine and uridine), which are absorbed intact.[1] In humans, dietary cytidine is converted into uridine, [2] which is probably the compound behind cytidine's metabolic effects.
There are a variety of cytidine analogs with potentially useful pharmacology. For example, KP-1461 is an anti-HIV agent that works as a viral mutagen,[3] and zebularine exists in E. coli and is being examined for chemotherapy. Low doses of azacitidine and its analog decitabine have shown results against cancer through epigenetic demethylation.[4]
