Phenylethylamine and tyramine are mixed-acting sympathomimetic amines in the brain.
On the helical strip of a capacitance vessel, the pulmonary artery of the rabbit, phenylethylamine (PEA) and tyramine act solely via displacement of noradrenaline from their storage sites and this… Expand
(−)1‐(Benzofuran‐2‐yl)‐2‐propylaminopentane, [(−)BPAP], a selective enhancer of the impulse propagation mediated release of catecholamines and serotonin in the brain

The brain constituents β‐phenylethylamine (PEA) and tryptamine enhance the impulse propagation mediated transmitter release (exocytosis) from the catecholaminergic and serotoninergic neurons in the… Expand
Sexual hormones terminate in the rat: the significantly enhanced catecholaminergic/serotoninergic tone in the brain characteristic to the post-weaning period.
The amount of dopamine released from the striatum, substantia nigra and tuberculum olfactorium, noradrenaline from locus coeruleus and serotonin from the raphe, was significantly higher in four and… Expand
Pharmacological studies with endogenous enhancer substances: β-phenylethylamine, tryptamine, and their synthetic derivatives
The discovery of enhancer regulation in the mesencephalon and the concept that it plays a key role in the operation of innate and acquired drives [Neurochem. Res. 28 (2003) 1187] sets the trace… Expand
Longevity study with low doses of selegiline/(-)-deprenyl and (2R)-1-(1-benzofuran-2-yl)-N-propylpentane-2-amine (BPAP).
AIMS The first longevity study demonstrating that rats treated with the MAO-B inhibitory dose of (-)-deprenyl (0.25mg/kg) lived significantly longer than their saline-treated peers was published in… Expand
Analysis of the analgesic and anti-inflammatory effects of rimazolium, a pyrido-pyrimidine derivative, compared with that of prostaglandin synthesis inhibitors and morphine.
- K. Gyires, S. Fürst, I. Miklya, I. Budavári, J. Knoll
- Drugs under experimental and clinical research
The analgesic, anti-inflammatory and gastrointestinal effects of rimazolium, morphine and prostaglandin synthesis inhibitors were compared in a battery of tests. Rimazolium, morphine and indomethacin… Expand
Enhanced catecholaminergic and serotoninergic activity in rat brain from weaning to sexual maturity: rationale for prophylactic (-)deprenyl (selegiline) medication.
Food deprived rats in the late developmental phase of life (2 months of age) are significantly more active than those in the early postdevelopmental phase (4 months of age), pointing to enhanced… Expand
(-)Deprenyl and (-)1-phenyl-2-propylaminopentane, [(-)PPAP], act primarily as potent stimulants of action potential-transmitter release coupling in the catecholaminergic neurons.
The activity of the catecholaminergic neurons in the rat brain is enhanced significantly 30 min after the subcutaneous injection of very small doses of (-)deprenyl (threshold doses: 0.01 mg/kg for… Expand
Sexually low performing male rats die earlier than their high performing peers and (-)deprenyl treatment eliminates this difference.
Out of 1600 sexually inexperienced 28-week old Wistar-Logan male rats 94 sexually inactive ('low performing', LP) and 99 highly active ('high performing', HP) rats were selected. The rats were… Expand
Multiple, small dose administration of (-)deprenyl enhances catecholaminergic activity and diminishes serotoninergic activity in the brain and these effects are unrelated to MAO-B inhibition.
As a measure of the basic activity of the catecholaminergic and serotoninergic systems, the biogenic amines released from freshly excised brain tissue were measured by means of HPLC with… Expand
