Abstract
Amide of lambertian acid suppresses hyperactivation of inotropic glutamate receptors in hippocampal sections induced by a decrease in the level of magnesium ions (a selective blocker of glutamate NMDA receptors). Treatment of the sections with amide of lambertian acid in standard physiological saline does not prevent development of NMDA-dependent synaptic potentiation. Lambertian acid isolated from needles and turpentine of Siberian pine (Pinus sibirica R. Mayr), and its derivatives may become a source of substances with glutamatergic mechanism of action for treatment of cognitive and neurodegenerative disorders.
Keywords:
amide of lambertian acid; hippocampal sections; hyperactivation of glutamatergic receptors; post-tetanic synaptic potentiation.
