Corticotrophin (ACTH) and its analogues, particularly Semax (Met-Glu-His-Phe-Pro-Gly-Pro), demonstrate nootropic activity. Close functional and anatomical links have been established between melanocortinergic and monoaminergic brain systems. The aim of present work was to investigate the effects of Semax on neurochemical parameters of dopaminergic- and(More)
The peptide Semax (MEHFPGP), which is an analogue of the ACTH (4–10) fragment, has a wide spectrum of activity in the nervous system of mammals, including humans. Using a model of neurotoxicity induced by hydroxydopamine, we studied the ability of Semax to prevent the death of tyrosine hydroxylase-positive neurons in a primary mixed neuroglial cell culture(More)
The synthetic peptide semax (a fragment of ACTH 4-7 Pro-Gly-Pro) enhances the release of extracell dopamine (DA) induced by D-amphetamine (5 mg/kg) in the striatum of Spraig-Dowley (SD) rats and increases the locomotor activity stimulated by D-amphetamine (2 mg/kg) in C57/BL6 mice. The basal content of DA, 3,4-dihydroxyphenylacetic acid (DHPAA), and(More)
Properties of AMPA type glutamate receptors widely presented within mammalian central nervous system are reviewed. AMPA receptors belong to ionotropic subclass of glutamate receptors and participate in fast excitatory glutamatergic transmission in the brain. Molecular structure of AMPA receptors consists of several subunits (GluRA1-GluRA4), which display(More)
