    ABSTRACT: Hemantane demonstrated a pronounced antiparkinsonian activity in the model of hemiparkinsonian syndrome provoked in rats by unilateral intracerebral injection of 6-hydroxydopamine, which was comparable to efficacy of levodopa in decreasing the duration of cataleptogenic state and the degree of akinesia of the contralesional forelimb assessed in the cylinder test. In the stepping test, hemantane exerted a long-term effect in contrast to levodopa, which diminished its beneficial action to the treatment day 21. In the swing test, the behavior normalized only by hemantane.

    ABSTRACT: We studied antihypoxic activity of analogs of endogenous cyclic dipeptide cycloprolylglycine in a mouse model of normobaric hypoxia with hypercapnia and found that antixypoxic effect depends on the structure of the substance. It was shown that different pharmacophores are responsible for the antihypoxic, nootropic, and anxiolytic effects of cycloprolylglycine.

    ABSTRACT: The experiments has been designed to study unpredictable chronic mild stress effect on anti-depressive activities of amitriptyline (10 mg/kg) and fluoxetine (20 mg/kg) in forced swim test in male outbred mice. It is shown that acute treatment with fluoxetine does not produce any antidepressant effects in mice following stress of 14 days while the sub-chronic injections of fluoxetine result in more deep depressive-like behavior. In 28 daily stressed mice, antidepressant effect of fluoxetine is observed independently of the injection rates. Amitriptyline demonstrates the antidepressant activity regardless of the duration of stress or administration scheduling, but at the same time the severity of anti-immobilization effect of amitriptyline in stressed mice is weaker in compare to non-stressed trails. Thus, the injection rates and duration of unpredictable mild chronic stress are the parameters that determine the efficiency of antidepressants in the mouse forced swimming test.

    ABSTRACT: We studied behavioral and neurochemical alterations that were induced by modeling of Alzheimer’s disease (AD) using bilateral intracerebroventricular administration of Aβ25-35 at a dose of 7.5 nmol in each ventricle. After 5.5 weeks, cognitive and psychoemotional alterations in the Morris spatial learning and Porsolt’s forced-swim tests were observed in rats with strong symptoms that are typical of AD. Measurement of the contents of monoamines and their metabolites in rat-brain structures was performed using the HPLC with the ECD method 1 day after the end of the tests. In the dorsal striatum, we found a decrease in the contents of metabolites of dopamine (DA), including homovanillic acid (HVA), 3,4-dihydroxyphenylacetic acid (DOPAC), and 3-methyltyramine (3-MT), and a decrease in the indices of DA utilization, including DOPAC/DA and HVA/DA, whereas the DA content was stable in this structure. In the nucleus accumbens (NA, ventral striatum), we found a decreased level of the HVA/DA ratio, which reflects the lower turnover of extracellular DA. We also found a lower turnover of serotonin (5-HT), which was seen as a decrease in the 5-hydroxyindolacetic acid (5-HIAA)/5-HT ratio, whereas the 5-HT content was elevated. In the hypothalamus, we revealed a significant decrease in the DA level and the levels of its metabolites, including 3-MT and HVA, and 5-HT turnover. We found that Aβ25-35 influenced the indices of amino-acidergic neurotransmission, which was reflected by the higher glutamate content in the striatum. Our data show that cerebral neurotransmitter systems, such as the tuberoinfundibular, mesolimbic, and nigrostrial dopaminergic and the striatal serotonergic and glutamatergic systems, are involved in pathophysiological mechanisms of the development of cognitive and psychoemotional impairments that occur in AD, as modeled by administration of Aβ25-35.

    ABSTRACT: Interoceptive stimulus properties of amitriptyline (54 mg/kg body weight), fluoxetine (10 mg/kg), and pyrrolo[1,2-a][1,4]diazepine derivative GMAL-24 (10 mg/kg) were studied in a standard operant model with liquid reinforcement of drug discrimination (DD) in male Wistar rats. A new experimental schedule that includes subchronic (7-day) administration of a training drug was used to perform DD learning. For the first time, it was found that amitriptyline has a discriminative interoceptive stimulus properties. Neither fluoxetine nor GMAL-24 did exhibit interoceptive properties. Imipramine (15 mg/kg, i.p.) fully substitutes for amitriptyline stimulus in substitution test. Fluoxetine (5 - 20 mg/kg, i.p.) failed to substitute with amitriptyline. Thus, amitriptyline/saline drug discrimination should be used for a comparative analysis of the central mechanisms of action of psychotropic substances, rather than for screening specific antidepressant activity.

    ABSTRACT: Anticonvulsant activity and pharmacokinetics of nanoemulsion and unmodified substance of carbamazepine were compared in experiments on mice. Carbamazepine nanoemulsion demonstrated significant anticonvulsant activity and was superior to unmodified substance of carbamazepine against seizures induced by maximum electric shock and picrotoxin. Relative bioavailability of carbamazepine after administration of nanoemulsion was 160% compared to unmodified substance. Carbamazepine nanoemulsion more effectively penetrated through BBB by 1.5 times in comparison with unmodified substance.

    ABSTRACT: The role of GABA-A receptors in psychotropic effects of pyrrolo[1,2-a][1,4]diazepine derivatives GMAL-24 and GMAL-27 has been studied on an operant method with liquid reinforcement of drug discrimination in male Wistar rats. It is established that, in substitution tests, GMAL-24 (2, 5, 10 mg/kg) and GMAL-27 (2, 5, 10 mg/kg) do not produce interoceptive effects of phenazepam (1 mg/kg) and fail to inhibit interoceptive effects of corasol (20 mg/kg). The obtained results indicate that pyrrolo[1,2-a][1,4]diazepine derivatives do not exhibit GABA-A receptor-positive modulator properties in vivo.

    ABSTRACT: Experiments on adult Wistar rats with streptozotocin-induced diabetes showed that antihyperglycemic activity of an original nootropic and neuroprotective drug Noopept (N-phenylacetyl-L-prolylglycine ethyl ester) is more pronounced under conditions of oral application than after intraperitoneal injection. These data provided a basis for studying the effect of Noopept on major indexes of the incretin system. Streptozotocin was shown to decrease the concentrations of incretin GLP-1 and insulin in the blood. Noopept had a normalizing effect on these parameters. This influence of Noopept was not related to the inhibition of a major enzyme metabolizing incretins (dipeptidyl peptidase IV). A reference drug sitagliptin also increased the contents of incretins and insulin, which was associated with the inhibition of dipeptidyl peptidase IV. It is known that GLP-1 increases NGF expression in the insular system. Our results suggest that the increase in incretin activity contributes to the antiapoptotic effect of Noopept on pancreatic β cells. The mechanism for an increase in blood GLP-1 level after oral application of Noopept requires further investigations.

    ABSTRACT: Levodopa-induced heavy dyskinesia was modeled in rats with severe hemiparkinsonian syndrome induced by injection of 6-hydroxydopamine in the left medial forebrain bundle. It is established that the antidyskinetic effect of the injectable dosage form of a new antiparkinsonian drug hemantane (5 mg/kg) after a single intravenous administration is weaker than that of the most effective in clinical practice antidyskinetic drug amantadine (20 mg/kg). However, after five days of treatment, the effect of hemantane injections exceeded that of amantadine.

    ABSTRACT: We have studied the influence of intraperitoneal introduction of a selective blocker of mitochondrial translocation protein 18kD PK11195 (5 mg/kg), indomethacin (5 and 10 mg/kg), finasteride (5 and 15 mg/kg), and neurosteroid pregnenolone (20 mg/kg) on the exploratory behavior of male BALB/c mice, C57BL/6 mice, and Wistar rats in open-field test. It is found that treatment with PK11195 weakens the exploratory behavior in open-field test in mice of both strains. Finasteride and indomethacin decrease the exploratory responses in rodents regardless of the species or type of stress emotional response phenotype. Pregnenolone possesses activating effect in open-field in open-field test, but enhances the inhibitory effect of finasteride in BALB/c mice.

    ABSTRACT: Developing diabetes was modeled on adult male Wistar rats by repeated intraperitoneal injections of streptozotocin in a subdiabetogenic dose of 30 mg/kg for 3 days. Proline-containing dipeptide drug Noopept or a standard diabetic drug dipeptidyl peptidase-4 inhibitor sitagliptin was administered per os in a dose of 5 mg/kg before each injection of the toxin and then for 16 days after streptozotocin course. In active control group, spontaneously increase glucose level and reduced tolerance to glucose load (1000 mg/kg intraperitoneally) were observed on the next day after the third administration of toxin. Basal glucose level decreased by day 16, but glucose tolerance remained impaired. Noopept normalized the basal blood glucose level and tolerance to glucose load on the next day after administration of streptozotocin. The effect of Noopept persisted to the end of the experiment. At early terms of the experiment, sitagliptin was somewhat superior to Noopept by the effect on baseline glucose level, but was inferior by the influence on glucose tolerance.. By the end of the experiment, Noopept significantly (by 2 times) surpassed sitagliptin by its effect on glucose tolerance.

    ABSTRACT: The pharmacodynamics and pharmacokinetics of hemisuccinate 3-hydroxyphenazepam (HS-3-HPh, levana)--a new hypnotic 1,4-benzodiazepine derivative--have been studied. It is established that HS-3-HPh in doses of 0.05, 0.1 and 2 mg/kg produces reliable hypnotic action (shortens the period of falling asleep, reduces the number of awakenings at night-time, and increases sleep duration) in the hexenal sleep potentiation test on mice. After a 7-day drug administration, no withdrawal syndrome has been observed. The concentration of 3-oxyphenazepam (3-OP, the main metabolite of HS-3-HPh) in brain after drug administration is significantly higher than the content of 3-OP upon its introduction. The content of 3-OP upon its introduction rapidly decreases, while that upon the administration of HS-3-HPh is retained on a stationary level for a rather long time (about 6 h). It can be suggested that a specific character of HS-3-HPh hypnotic action is determined by peculiarities of its pharmacokinetics, namely, easier entering the brain and subsequent hydrolysis with release of the active metabolite (3-OP).

    ABSTRACT: Hemantane is a novel antiparkinsonian drug that is undergoing clinical trials. Hemantane in the dosage range 10 – 40 mg/kg demonstrated anti-inflammatory activity and decreased statistically significantly the intensity of the exudative reaction in an acetic-acid peritonitis model in mice. Hemantane (10 mg/kg) in a neuro-inflammation model induced by lipopolysaccharide injection in rats prevented loss of body mass, development of forepaw akinesia contralateral to the operation, and smell disturbance.

    ABSTRACT: The research on the nansomal forms s of low-sialylated recombinant human erythropoietin (ls-rhEPO) gave evidence for the efficiency of the nanotechnological approach to targeted delivery of this protein to the brain of experimental animals. Nanosomal ls-rhEPO formulations were found to exhibit neuroprotector activity. The established ability of the nanosomal formulations of ls-rhEPO to enhance BDNF and NGF gene expression in animal brain is to a great extent responsible for the mechanism of the neuroprotector action of this protein.

    ABSTRACT: A series of new 1,2,4,5-tetrahydro-3H-pyrrolo[1,2-a][1,4]diazepin-3-one derivatives were synthesized from widely available furfurol, 3-aminopropionic acid, and amines. The antidepressant and anxiolytic properties of the obtained compounds were investigated. Results of Nomura and Porsolt forced swimming tests showed that some of the compounds exhibited antidepressant activity at doses of 7 μmol/kg (1.1 – 2.2 mg/kg). Use of the Vogel conflict test showed that several compounds possessed anxiolytic activity at the same doses. The activities of the most active compounds exceeded those of the reference drugs, antidepressant amitriptyline and daily tranquilizer medazepam, at doses of 10 mg/kg.

    ABSTRACT: A large amount of clinical and experimental data suggest the involvement of neurotrophins, in particular the brain-derived neurotrophic factor (BDNF), in depression pathogenesis. However, the therapeutic use of BDNF is limited because of its instability in biological fluids, poor blood-brain barrier (BBB) permeability, and the presence of side effects. A low-molecular-weight mimetic GSB-106, which is a substituted dimeric dipeptide bis(N-monosuccinyl-L-seryl-L-lysine)hexamethylenediamide, was designed and synthesized based on the BDNF fourth loop structure at the V.V. Zakusov Institute of Pharmacology (RAMS). GSB-106 was found to exhibit an antidepressant activity in various models of depressive-like state when administered intraperitoneally to outbred mice and rats. An effect for the substance, when administered daily for 4-5 days, was detected in the Porsolt forced swimming test (0.1 and 1.0 mg/kg) and in the tail suspension test in mice (1.0 and 1.5 mg/ kg). An effect for GSB-106 at doses of 0.1 and 0.5 mg/kg was observed after a single application in experiments on rats in the Nomura water wheel test. The obtained evidence supports the hypothesis on the involvement of BDNF in the pathogenesis of various depression conditions, thus opening prospects for searching for new original antidepressants.
