Abstract
Alpha-methyltryptamine (AMT), 5-methoxy-alpha-methyltryptamine (5-MeO-AMT), and 5-methoxy-N,N-diisopropyltryptamine (5-MeO-DiPT) are synthetic tryptamines with hallucinogenic-like properties that are widely abused worldwide. There, however, has been a paucity of research and a lack of available data on their pharmacological properties. The objective of this study was to investigate the safety of AMT and 5-MeO-DiPT and to compare the effects of AMT, 5-MeO-AMT, and 5-MeO-DiPT under identical conditions in terms of locomotor performance and hallucinogenic-like behavior, and the role of 5-hydroxytryptamine-2A receptor antagonists (M100907) on hallucinogenic-like behavior. The results showed that both AMT and 5-MeO-DiPT exhibited some acute toxic effects. AMT, 5-MeO-AMT, and 5-MeO-DiPT inhibited locomotor activity and induced head-twitch response (HTR) in mice. Pretreatment with M100907 (0.01 mg/kg) blocked AMT, 5-MeO-AMT, and 5-MeO-DiPT induced HTR in mice. The findings of this study demonstrated that the three tryptamines are toxic, inhibit locomotor activity, and have hallucinogenic effects. These results provide experimental data that can provide fundamental support for future control strategies and in-depth mechanistic studies of these substances.
期刊介绍：
Behavioural Pharmacology accepts original full and short research reports in diverse areas ranging from ethopharmacology to the pharmacology of schedule-controlled operant behaviour, provided that their primary focus is behavioural. Suitable topics include drug, chemical and hormonal effects on behaviour, the neurochemical mechanisms under-lying behaviour, and behavioural methods for the study of drug action. Both animal and human studies are welcome; however, studies reporting neurochemical data should have a predominantly behavioural focus, and human studies should not consist exclusively of clinical trials or case reports. Preference is given to studies that demonstrate and develop the potential of behavioural methods, and to papers reporting findings of direct relevance to clinical problems. Papers making a significant theoretical contribution are particularly welcome and, where possible and merited, space is made available for authors to explore fully the theoretical implications of their findings. Reviews of an area of the literature or at an appropriate stage in the development of an author’s own work are welcome. Commentaries in areas of current interest are also considered for publication, as are Reviews and Commentaries in areas outside behavioural pharmacology, but of importance and interest to behavioural pharmacologists. Behavioural Pharmacology publishes frequent Special Issues on current hot topics. The editors welcome correspondence about whether a paper in preparation might be suitable for inclusion in a Special Issue.
