Acute administration of alpha-benzyl-N-methylphenethylamine (ABNMP) induces lateral heavings, straub tail, backward locomotion, and hindlimb abduction-which are all components of the serotonin (5-HT) syndrome. Ketanserin, a 5-HT-2 receptor antagonist and pretreatment with the 5-HT neurotoxin parachlorophenylalanine (PCPA) attenuated the manifestation of these behavioral abnormalities. These results suggest that ABNMP may cause an acute release of 5-HT similar to that elicited by para-chloroamphetamine.

Rationale: Because of their potential therapeutic effects, N-methyl-D-aspartate (NMDA) receptor antagonists have been investigated for clinical use. Unfortunately, many channel-blocking antagonists have been associated with the production of side effects, including motor impairment and phencyclidine (PCP)-like subjective effects.
Objective: This study investigated the relationship between NMDA receptor channel blockade and production of PCP-like side effects by evaluating a variety of NMDA channel blockers with different binding characteristics for the production of PCP-like discriminative stimulus effects.

alpha-Benzyl-N-methylphenethylamine (BNMPA), an impurity of illicit methamphetamine synthesis, has previously been reported to produce convulsions in mice without affecting spontaneous locomotor activity or altering methamphetamine-induced increases in spontaneous activity. In this study the in vitro effects of BNMPA on a variety of neuronal receptor types was determined to better characterize the pharmacological actions of this novel compound. BNMPA and N-demethyl-BNMPA fully displaced the dopamine transporter selective ligand [3H]CFT (2-beta-carbomethoxy-3-beta-(4-fluorophenyl)tropane) from rat striatal membranes with Ki values (mean +/- S.

Eighty urine specimens collected from drug rehabilitation programs, which had been screened by immunoassay and confirmed positive by gas chromatography-mass spectrometry (GC-MS) for methamphetamine, were further analyzed for alpha-benzyl-N-methylphenethylamine (BNMPA) and its urinary metabolites, N-demethyl-BNMPA, diphenyl-2-propanone (DP2P), diphenyl-2-propanol, p-OH-N-demethyl-BNMPA, and p-OH-BNMPA. BNMPA is an impurity of illicit methamphetamine synthesis. Analysis of BNMPA and its metabolites was performed by quantitative GC-MS following beta-glucuronidase hydrolysis, liquid-liquid extraction, and derivatization with heptafluorobutyric anhydride.

Methamphetamine is a popular drug of abuse, which is readily synthesized in clandestine laboratories. Illicit synthesis results in the formation of various contaminants. Few impurities have been studied in vivo, and their metabolic fate is unknown.
