This phenomenon, named excitotoxicity, has also been implicated in epileptic seizures and various chronic and progressive neurodegenerative diseases, such as Huntington’s chorea, Alzheimer’s disease, and Parkinson’s disease. Injury (trauma or ischemia) in the brain triggers an abnormal release of glutamate and other excitatory aminoacids that contribute significantly to neuronal death. These results indicate that the nucleotides included in Nucleo CMP Forte ® are promising therapeutic molecules for the prevention of neuronal death in brain caused by focal ischemia, Parkinson’s disease or other neurodegenerative pathologies. More interestingly, drug pre-treatment significantly reduced MPP +- and glutamate-induced cell death in SH-SY5Y cells and in rat cortical cells. Nucleo CMP Forte ® pre-treatment significantly increased the rate of cell division in SH-SY5Y cells, as well as the synthesis of triglycerides and phospholipids. Cell viability was measured at different times. We used the human dopaminergic cell line SH-SY5Y and a primary culture of rat cortical cells pre-treated with the drug for 24 hours and then exposed to MPP + or glutamate at a range of concentrations. We examined its neuroprotective effects on cell toxicity induced by glutamate excitotoxicity or by 1- methyl-4-phenyl-pyridinium (MPP +), an in vitro cell model of Parkinson’s disease. Its effects on brain pathologies has received little attention. It has been prescribed for peripheral nervous system disorders, such as lumbosciatalgia, diabetic or alcoholic polyneuropathy, or trigeminal neuralgia. Nucleo CMP Forte ® is a nucleotide-based drug consisting of cytidinemonophosphate, uridinemonophosphate, uridinediphosphate and uridinetriphosphate.
