BACKGROUND Reboxetine is a potent antidepressant, with efficacy comparable to that of imipramine, desipramine, and fluoxetine, and has improved side-effect profile. The basis of its efficacy and improved tolerability is sought through studies of reboxetine in a number of pharmacological models of depression. METHODS Pharmacological selectivity for uptake(More)
Both 5-HT1A and 5-HT2A receptors have been implicated in modulating ethanol self-administration. A novel serotonergic compound, FG 5974, with combined 5-HT1A agonist/5-HT2A antagonist activities, has shown effects in decreasing ethanol consumption in two-bottle choice paradigms. In the present study, the effect of this compound on operant responding for(More)
PNU-151774E [(S)-(+)-2-(4-(3-fluorobenzyloxy) benzylamino) propanamide, methanesulfonate] is a structurally novel anticonvulsant having Na+ channel-blocking and glutamate release-inhibiting properties, as well as being a MAOB inhibitor. Its anticonvulsant activity was evaluated in the maximal electroshock (MES) test and in chemically induced seizures(More)
The technique of dietary self-selection has been widely used to investigate proposed mechanisms of protein and carbohydrate regulation and to substantiate theories relating nutrients, brain chemistry and behaviour. These experiments have produced conflicting results which might be accounted for by differences in experimental variables or in the different(More)
The present studies sought to elucidate the role of 5-HT2A receptor antagonists in suppressing alcohol intake by comparing the effects of amperozide and FG 5974 on alcohol, food, and water intake in strains of alcohol-preferring rats: P, Alko Alcohol (AA), and Fawn-Hooded (FH). Both amperozide and FG 5974 have 5-HT2A receptor antagonist properties, but FG(More)
Prion diseases are transmissible neurodegenerative conditions characterized by the accumulation of protease-resistant forms of the prion protein (PrP), termed PrPres, in the brain. Insoluble PrPres tends to aggregate into amyloid fibrils. The anthracycline 4'-iodo-4'-deoxy-doxorubicin (IDX) binds to amyloid fibrils and induces amyloid resorption in patients(More)
Kainic acid-induced multifocal status epilepticus in the rat is a model of medically intractable complex partial seizures and neurotoxicity. The exact mechanisms of kainic acid epileptogenic and neurotoxic effects are unknown, but enhanced glutamate release seems to be an important factor. PNU-151774E ((S)-(+)-2-(4-(3-fluorobenzyloxy) benzylamino)(More)
Two experiments examined the possibility that mice rendered obese by systemic injection of goldthioglucose (GTG) possess altered endogenous levels of brain norepinephrine (NE), dopamine (DA), serotonin (5-hydroxytryptamine or 5HT) and/or 5-hydroxyindoleacetic acid (5HIAA). In the first experiment, single-housed GTG-obese mice were found to have normal brain(More)
Sodium channel blocking, anticonvulsant activity, and sigma (sigma) binding of selected leads in a series of alpha-amino amide anticonvulsants were examined. While anticonvulsant compounds were always endowed with low micromolar sodium (Na+) channel site-2 binding, compounds with low site-2 Na+ channel affinity failed to control seizures. No correlation(More)
