[On the mechanism of noopept action: decrease in activity of stress-induced kinases and increase in expression of neutrophines].

[Article in Russian]

Abstract

The influence of noopept (N-phenylacetyl-L-prolylglycine ethyl ester, GVS-111)--a drug combining the nootrope and neuroprotector properties--on the activity of mitogen-activated protein kinases (MAPKs) and the level of NGF and BDNF gene and protein expression in the frontal cortex, hippocampus, and hypothalamus has been studied in rats. Under conditions of chronic administration (28 days, 0.5 mg/day, i.p.), noopept decreased the activity of stress-induced kinases (SAPK/JNK 46/54 and pERK1/2) in rat hippocampus and increases the level of mRNA of the BDNF gene in both hypothalamus and hippocampus. The content of BDNF protein in the hypothalamus was also somewhat increased. In the context of notions about the activation of stress-induced kinases, as an important factor of amyloidogenesis and tau-protein deposition in brain tissue, and the role of deficiency of the neurotrophic factors in the development of neurodegenerative processes, the observed decrease in the activity of stress-activated MAPKs and increased expression of BDNF as a result of noopept administration suggest thatthis drug hasaspecific activity withrespect to some pathogenetic mechanisms involved in the Alzheimer disease.
