Long regarded as illicit substances with no clinical value, N-dimethylated tryptamines—such as N,N-dimethyltryptamine, 5-methoxy-N,N-dimethyltryptamine, and bufotenine—have been found to produce naturally in a wide variety of species, including humans. Known for their psychoactive effects through serotonin receptors (5-HTRs), N-dimethylated tryptamines are currently being reinvestigated...

Nowadays, the renaissance of psychedelics in...

Ayahuasca is made by the decoction of two plants, which are rich in the 5-HT1A/2A partial agonist dimethyltryptamine or DMT (from the leaves of the Psychotria viridis bush) and β-carbolines such as...

The present work investigated the anxiolytic effect of the alkaloid fraction (AF II) from the root bark of Mimosa tenuiflora. Female Swiss mice of 6 weeks old were used in this study. The animals were divided into three groups: 0.9% NaCl (vehicle group, s.c.), AF II (6 mg/kg, s.c.), and diazepam - DZP (5 mg/kg, s.c.). The light/dark box and elevated plus maze tests evaluated the animal anxiety....

Psychedelics have emerged as promising therapeutics for several psychiatric disorders. Hypotheses around their mechanisms have revolved around their partial agonism at the serotonin 2 A receptor, leading to enhanced neuroplasticity and brain connectivity changes that underlie positive mindset shifts. However, these accounts fail to recognise that the gut microbiota, acting via the gut-brain...

The psychedelic beverage ayahuasca is originally obtained by Banisteriopsis caapi (B. caapi) (BC) and Psychotria viridis (P. viridis) (PV). However, sometimes these plant species are replaced by others that mimic the original effects, such as Mimosa hostilis (M. hostilis) (MH) and Peganum harmala (P. harmala) (PH). Its worldwide consumption and the number of studies on its potential therapeutic...

A recent report by Chen et al. describes the discovery of RmNMT, a highly active and promiscuous tryptamine N-methyltransferase from the cane toad, Rhinella marina. N,N-dimethyltryptamine derivatives produced by this enzyme were then evaluated for their potential to serve as next-generation treatments for mental health disorders.

Ayahuasca is a beverage used in Amazonian traditional medicine and it has been part of the human experience for millennia as well as other different psychoactive plants. Although Ayahuasca has been proposed as potentially therapeutic as an anxiolytic and antidepressant, whilst no studies have been carried out so far investigating their direct effect on brain emotional processing. This study...
