cytidine diphosphate sodium

Cytidine 5'-diphosphate disodium (CDP sodium salt) produces CTP to support DNA and RNA biosynthesis and ribonucleotide reductase to produce dCMP.

Citicoline sodium (CDP-choline) is an endogenous intermediate in the synthesis of phosphatidylcholine. It also serves as a choline donor in the biosynthesis of the neurotransmitter acetylcholine. Citicoline sodium demonstrates protective effects in cerebral ischemia, traumatic brain injury, and memory disorders. Exogenous administration of citicoline to rodents (500 mg/kg i.p. immediately after ischemia and at 3-h reperfusion) has been shown to stimulate the synthesis of phosphatidylcholine, sphingomyelin, and cardiolipin and to attenuate the release of arachidonic acid and the accumulation of ceramide.

Cytidine 5′-diphosphat (5'-CDP) is synthesized from cytidine monophosphate (CMP) or uridine monophosphate (UMP) by the transfer of phosphoryl group, catalyzed by the enzyme uridylate kinase (UMPK).
