The phenethylamine-derived designer drug 4-ethyl-2,5-dimethoxy-beta-phenethylamine (2C-E) was found to be mainly metabolized in rats by O-demethylation, N-acetylation, hydroxylation of the ethyl side chain at C2' or at C1' followed by oxidation at C1' to the corresponding ketone, by deamination followed by reduction to the corresponding alcohols or by oxidation to the corresponding acids, and finally combinations of these steps. Most of the metabolites were excreted in conjugated form. The authors' systematic toxicological analysis (STA) procedure using full-scan GC-MS allowed the detection of an intake of a dose of 2C-E in rat urine that corresponds to a common drug users' dose. Assuming similar metabolism, the described STA procedure should be suitable for proof of an intake of 2C-E in human urine. /4-Ethyl-2,5-dimethoxy-beta-phenethylamine (2C-E)/
The in vivo metabolism of 2,5-dimethoxy-4-propylthiophenethylamine (2C-T-7), a ring-substituted psychoactive phenethylamine, was studied in rat. Male Wistar rats were administered 10 mg/kg 2C-T-7 hydrochloride orally, and 24-hr urine fractions were collected. After enzymatic hydrolysis of the urine sample, the metabolites were extracted by liquid-liquid extraction and analyzed by liquid chromatography/mass spectrometry. 2C-T-7-sulfoxide, N-acetyl-2C-T-7-sulfoxide, N-acetyl-2,5-dimethoxy-4-methylthiophenethylamine-sulfoxide, N-acetyl-2,5-dimethoxy-4-(2-hydroxypropylthio)phenethylamine-sulfoxide, and N-acetyl-2,5-dimethoxy-4-(2-hydroxypropylthio)phenethylamine-sulfone were detected as the primary metabolites of 2C-T-7. These findings suggest that sulfoxidation, sulfone formation, hydroxylation of the propyl side chain at the beta-position, and S-depropylation followed by methylation of thiol were the major metabolic pathways of 2C-T-7 in rat.
Studies are described on the metabolism and the toxicological analysis of the phenethylamine-derived designer drug 2,5-dimethoxy-4-ethylthio-beta-phenethylamine (2C-T-2) in rat urine using gas chromatography/mass spectrometry (GC/MS) after enzymatic cleavage of conjugates, liquid-liquid extraction and derivatization. The structures of 14 metabolites were assigned tentatively by detailed interpretation of their mass spectra. Identification of these metabolites indicated that 2C-T-2 was metabolized by sulfoxidation followed by N-acetylation and either hydroxylation of the S-ethyl side chain or demethylation of one methoxy group, O-demethylation of the parent compound followed by N-acetylation and sulfoxidation, deamination followed by reduction to the corresponding alcohol followed by partial glucuronidation and/or sulfation or by oxidation to the corresponding acid followed either by partial glucuronidation or by degradation to the corresponding benzoic acid derivative followed by partial glucuronidation. Furthermore, 2C-T-2 was metabolized by N-acetylation of the parent compound followed either by O-demethylation and sulfoxidation or by S-dealkylation, S-methylation and sulfoxidation. The authors' systematic toxicological analysis (STA) procedure using full-scan GC/MS after acid hydrolysis, liquid-liquid extraction microwave-assisted acetylation allowed the detection of an intake of a dose of 2C-T-2 in rat urine, which corresponds to a common drug users' dose. Assuming similar metabolism, the described STA procedure should be suitable for proof of an intake of 2C-T-2 in human urine. /2,5-Dimethoxy-4-ethylthio-beta-phenethylamine (2C-T-2)/
Basic Treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Encourage patient to take deep breaths. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... . /Irritating materials/
Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Early intubation at the first sign of upper airway obstruction may be necessary. Positive-pressure ventilation techniques with a bag valve mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Monitor cardiac rhythm and treat arrhythmias if necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of fluid overload ... .Treat seizures with diazepam or lorazepam ... Use proparacaine hydrochloride to assist eye irrigation ... . /Irritating materials/
/SIGNS AND SYMPTOMS/ 2C-T-7 produces negative physical and psychological effects in users. Physical effects include visual and auditory disturbances and distortions, increased blood pressure, blurred vision, dehydration, dilated pupils, headaches, irregular heartbeat, jaw clenching, nausea, and vomiting. Psychological effects associated with the use of 2C-T-7 include emotional distress, hallucinations, inability to sleep, irritability, loss of memory, nervousness, restlessness, and tension. Additionally, 2C-T-7 can cause impaired judgment, leading abusers to engage in dangerous activities. Compounding these risks is the uncertainty of the 2C-T-7 dosage in a particular tablet, capsule, or quantity of powder--high dosages can cause overdoses and death. At least three deaths have been associated with 2C-T-7 abuse.
