A synthetic peptide analog of ACTH(4-10) developed in Russia, studied for nootropic, neuroprotective, and anxiolytic effects.
Gateways to Clinical Trials is a guide to the most recent clinical trials in current literature and congresses. The data in the following tables have been retrieved from the Clinical Trials Knowledge Area of Prous Science Integrity, the drug discover…
The present concept of relative instability of regulatory peptides (RPs) in organisms must be amended. The recently characterized family of glyprolines and some other prolyl-glycyl-proline (PGP)-containing oligopeptides show the stability quite compa…
We studied the effect of neonatal treatment with pharmacological preparations (Semax and buspiron) and solvents (distilled water and physiological saline) on the pain threshold in 3-4-month-old mice of 6 genotypes. Neonatal administration of the solv…
The binding characteristics of the peptide Semax (Met-Glu-His-Phe-Pro-Gly-Pro) to plasma membranes of basal nuclei of the rat forebrain and the dynamics of its degradation during its incubation with these membranes were studied. Binding of the homoge…
This report describes studies cf the effects of the ACTH(4-10) analog Semax (MEHFPGP) on the behavior of white rats with lesions to the brain dopaminergic system induced by the neurotoxin MPTP. Neurotoxin was given as single i.p. doses of 25 mg/kg. N…
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-amphet…
In order to substantiate the feasibility of using the "Semax" neuroprotector in the treatment of optic-nerve diseases its pharmacokinetics in the intranasal administration was studied in experiments with rats; besides, the physical-and-chemical prope…
DBA/2, CBA mice, and their F1 hybrids (first series) and 101/HY and C3H mice (second series) were injected as neonates (2-7 days of life) with Semax (sc., 7 microg per animal). Semax is a peptide analogue of ACHT4-10 fragment which is resistant to de…
Semax and mexidol significantly increase the survival of white mongrel male mice upon bilateral ligation of common carotid arteries. Semax virtually completely prevented retrograde amnesia development in ligated mice under conditions of a complex ext…
As respiratory sounds contain mechanical and clinical pulmonary information, technical efforts have been devoted during the past decades to analysing, processing and visualising them. The aim of this work was to evaluate deterministic interpolating f…
It is suggested to reproduce a retrograde amnesia in mice by means of a complex extremal action: emaciating swim in cold water with simultaneous wheel rotation. It was found that nootropes such as pyracetam, mexidol, semax, nooglutil, acephen, and no…
One-hour immobilization stress considerably disturbed microcirculation in the mesentery: blood flow in small mesenteric vessels decreased or stopped and numerous hemorrhages appeared. Lymphatic vessels lost spontaneous activity and did not respond to…
Stress increased secretory activity of mast cells in the mesentery and subcutaneous fat of rats. Intraperitoneal injection of Semax and prolyl-glycyl-proline in doses of 0.05 and 1 mg/kg, respectively, 1 h before stress abolished this effect. The tes…
Previously we showed that peptides PGP, PG, GP and semax have protective anti-ulcer properties using different models of ulcerogenesis. Semax (MEHFPGP) is a nootropic analogue of adrenocorticotropin 4-7 stabilized by PGP in the C-terminal region. In…
This report describes studies of the characteristics of serum albumin in rats with different predicted levels of resistance to emotional stress in control conditions and in conditions of experimental emotional stress. The effects of peptides increasi…
We studied the effect of exposure to acute hypobaric hypoxia in the progestational period on the content of biogenic amines in the brainstem and cerebral cortex in rat pups of different age. The possibility of correcting hypoxia-induced changes with…
We studied immediate and delayed changes in ECG in female albino rats subjected to acute hypobaric hypoxia on days 4-5 of pregnancy and evaluated the possibility of correction of hypoxia-produced disturbances with some peptides. Acute hypoxia lengthe…
