As the second and concluding part, this paper continues the summary review of the scientific evidence obtained from the literature and focuses on the remaining 4/6 groupings of DDs identified in illegal products found in the huge drug seizures made recently in Poland. They consist of
Seven L-amino acids (Trp, Arg, Lys, Met, Ile, Val, and Phe) partially (28-81%) reversed the inhibitory action of 1 microM gamma-aminobutyric acid (GABA) on t-[35S]butylbicyclophosphorothionate ([35S]TBPS) binding to rat brain membranes, with EC50 values ranging from 5 to 120 mM. D-Trp, D-Arg, D-Lys,
Beta-carbolines and indoloquinolizidines occur in plants, and some of the former compounds also in mammalian tissues. Many beta-carbolines cause tremor or convulsions, and they are among the most potent known endogenous compounds to bind to benzodiazepine, tryptamine and serotonin binding sites. In
Ecstasy is the name given to a large group of substances known as "club drugs" traded in the form of tablets, powder and liquid that present a varied composition, including mainly 3,4-methylenedioxymethamphetamine (MDMA) and analogous substances, in addition to the growing presence of new
The functional significance of the interaction between serotonergic and dopaminergic neurotransmission is still uncertain. To document this interaction further, specific behavioral responses of rats to tryptamine and apomorphine were studied. The sequential injection of these agonists, at time
Tryptamine alkaloid toxicosis (Phalaris staggers) was diagnosed in feedlot sheep. Clinical signs of toxicosis, which were exacerbated by excitement, included gait abnormalities, muscular tremors, nystagmus, and convulsions. An estimated 8% of the most severely affected lambs had clinical signs of
Infant rats, treated intracisternally with 6-hydroxydopamine or 5,7-dihydroxytryptamine, alone or in combination with desmethylimipramine or pargyline, at 5 to 7 days of age, had significant specific depletions of brain norepinephrine, dopamine, both of these amines, or serotonin at 2.5 months of
The pharmacological properties of a phenothiazine derivative thioproperazine have been compared with those of chlorpromazine, and the modifications by some anti-Parkinsonian drugs of its actions on the central nervous system have been studied. Thioproperazine was less potent than chlorpromazine in
Over the last few years, hundreds of new psychoactive substances (NPS) have been identified in Europe. Apart from some herbal compounds, NPS mainly include synthetic cannabinoids and a range of new synthetic stimulants (e. g., cathinones). Synthetic NPS are often developed whilst modifying the basic
New psychoactive stimulants appeared in Hungary in 2010 as in several other European countries. We present our findings from cases where new psychoactive and conventional stimulants (we listed amphetamine, methamphetamine and MDMA as conventional drugs) have been detected in biological specimens
The neuropharmacological profile of the total fungal extract of F. moniliforme (FM) has been investigated. FM produced dose related decrease in spontaneous motor activity (SMA) and exploratory activity, potentiated pentobarbitone hypnosis and the anticonvulsant actions of phenobarbitone and
