摘要：The urinary metabolic profiles of three hallucinogenic 2,5-dimethoxy-4-alkylthiophenethylamine analogs: 2,5-dimethoxy-4-ethylthiophenethylamine (2C-T-2), 2,5-dimethoxy-4-isopropylthiophenethylamine (2C-T-4), and 2,5-dimethoxy-4-propylthiophenethylamine (2C-T-7), were investigated in rats. For each drug, four male Sprague-Dawley rats were orally administered 10 mg/kg of 2C-T-2, 2C-T-4, or 2C-T-7, and urine was collected 0–24 and 24–48 h after administration. The urine samples were processed by liquid–liquid extraction, and the extracts were analyzed by liquid chromatography/mass spectrometry to quantify the metabolites. The metabolic patterns of these drugs were different: for 2C-T-7, the principal metabolite was the β-hydroxylated- N -acetylated-sulfoxide, whereas for 2C-T-2 and 2C-T-4 the major metabolites were the N -acetylated-sulfoxide and S -methylated- N -acetylated-sulfoxide, respectively.
