1-Methyl-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid (MTCA) is one of the metabolites of peak E substance, which, based on epidemiological studies, has been thought to be a possible causative agent of the tryptophan-induced eosinophilia-myalgia syndrome. Acute ethanol and L-tryptophan administration in rats pretreated with

A high-performance liquid chromatographic method was developed to quantify 1,2,3,4-tetrahydro-beta-carboline (TBC) and 1-methyl-1,2,3,4-tetrahydro-beta-carboline (MTBC) in human urine. Urine samples with added internal standard were subjected to a reaction with fluorescamine and solvent extractions to remove the precursor tryptamine, which readily

The excretion and distribution of 14C were studied in rats given by oral intubation 14C-labelled (-)-(1S,3S)-1-methyl-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid and its stereoisomer, (-)-(1R,3S)-1-methyl-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid (MTCAs), compounds that are known to become mutagenic on reaction with nitrite. For comparison, another group of rats
