General description

Cytidine 5′-diphosphocholine (CDP-choline) contains cytidine and choline linked via a diphosphate bridge.

Application

Cytidine 5′-diphosphocholine sodium salt dihydrate has been used as a physiological metabolite for the identification of gemcitabine diphosphate choline (GdPC) by liquid chromatography-mass spectrometry (LC-MS/MS) method in the Kennedy pathway .

Biochem/physiol Actions

Cytidine 5′-diphosphocholine (CDP-choline) plays an important role in the synthesis of phosphatidylcholine. It is also involved in the biosynthesis of acetylcholine, a neurotransmitter. CDP-choline has therapeutic effects against hypoxia, cerebral ischemia and traumatic brain injury. It also exhibits therapeutic effects against learning and memory disorders, drug addiction and Alzheimer′s and Parkinson′s diseases.

Brain phosphatidylcholine (PC) levels are regulated by a balance between synthesis and hydrolysis. Pro-inflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 (IL-1alpha/beta) activate phospholipase A(2) (PLA(2)) and PC-phospholipase C (PC-PLC) to hydrolyze PC. PC hydrolysis by PLA(2) releases

Potential therapeutic effects of cytidine 5-diphosphocholine (citicoline), a key intermediary in the biosynthesis of the membrane phospholipid, phosphatidylcholine, are presumably related to enhanced phospholipid synthesis in the ischemic brain. We evaluated prolonged citicoline treatment in a temporary focal ischemia model.
