Some aromatic 1-aryl(and 1-aralkyl)-β-carbolines were prepared from their tetrahydro analogues by dehydrogenation over palladium on charcoal either in a Parr bomb or in refluxing toluene. The bomb reaction appears to be a better procedure for the pr

The distribution and metabolic fate of [3H]harmaline-HCl were studied in rats. Thirty min after subcutaneous injection, high radioactivity was found in the small intestine, liver, adrenals, kidneys and lungs. A rapid turnover and elimination was evid

During previous studies on the inhibition of hydroxyindole-O-methyltransferase, several N-acyltryptamines have been found to be good inhibitors of this enzyme. Substitution of the benzyl or phenyl moiety of N-phenylacetyltryptamine or N-benzoyltrypta

Several analogs of tetrahydro-β-carboline (I) and 9-methyltetrahydro-β-carboline (VII) with substituents on C-6 or C-8 were synthesized. Methylation of the N-9 position of a tetrahydro β-carboline is generally achieved in the presence of a base. H

A series of 9-alkyl aromatic-β-carbolines was synthesized and evaluated as inhibitors of mitrochondrial monoamine oxidase. The possible existence of a hydrophobic or hydrophilic region on the enzyme was explored. Substitution of an electron-withdraw

A number of 6(or 8)-substituted aromatic β-carbolines were synthesized, and their inhibitory activities toward monoamine oxidase were compared with their tetrahydro congeners. A considerable difference in the effects of 6(or 8)-substitution on the i

Several N-acyltryptamines were found to inhibit hydroxyindole-O-methyltransferase. Of these inhibitors the most active was N-phenylacetyltryptamine, having an affinity to the enzyme six times greater than the substrate N-acetylserotonin. These studie

The hallucinogen 2,5-dimethoxy,-4-methylamphetamine, also known as STP, accumulates in specfic areas of cat brains. The unchanged compound was detected in the brain for at least 6 hours, whereas its behavioral effects lasted for about 4 hourS. The co
