Psychedelic indolethylamines have emerged as potential medicines to treat several psychiatric pathologies. Natural sources of these compounds include 'magic mushrooms' (Psilocybe spp.), plants used to prepare ayahuasca, and toads. The skin and parotid glands of certain toads accumulate a variety of specialized metabolites including toxic guanidine alkaloids, lipophilic alkaloids, poisonous...
A ayahuasca é uma bebida alucinógena originária na América do Sul, utilizada por indígenas em rituais xamânicos. É obtida através da fermentação de duas plantas, a folha da P. viridis, na qual é obtida a dimetiltriptamina (DMT), substância responsável pelos efeitos alucinógenos e o cipó B. caapi que contém β-carbolinas (harmina, harmalina e tetraidro-harmina). As β-carbolinas impedem a...
This paper examines the possible consequences of medicalising the psychedelic Ayahuasca to be used as a treatment for depression. Through a science and technology studies (STS) understanding of the social construction of scientific facts, I consider how traditional indigenous uses of Ayahuasca are translated into Western medicine. Two special points of attention are: (1) the cultural...
Neurological diseases often involve changes in synaptic connectivity and plasticity. Psychoplastogens, substances that stimulate neuronal growth and enhance neural structures, show promise in mitigating these changes. They activate key biological targets, including AMPA receptors, TrkB, and mTOR. Substances like ketamine, scopolamine, N,N-dimethyltryptamine, and rapastinel have...
Psychedelics as therapeutic agents have generated significant attention from clinicians and media sources in recent years. The authors provide an update to the psychiatric trainee on the evidence for psychedelics in the treatment of major depressive disorder and treatment-resistant depression. Many modern clinical trials of the classic, serotonergic psychedelics, such as psilocybin, ayahuasca,...

Abstract Serotonergic psychedelics, such as lysergic acid diethylamide (LSD), psilocybin, dimethyltryptamine (DMT), and 5‐methoxy‐ N , N ‐dimethyltryptamine (5‐MeO‐DMT), are currently being investigated for the treatment of psychiatric disorders such as depression and anxiety. Clinical trials with psilocybin and LSD have shown improvement in emotional and psychological scores. Although these...
There has been a resurgence of interest in the use of psychedelic therapies for several mental and substance use disorders. Psilocybin, a "classic" serotonergic psychedelic, has emerged as one of the primary compounds of interest in clinical research. While research on psilocybin's potential mental health benefits has grown, data on the safety and efficacy of other serotonergic psychedelics...
Intestinal inflammation and dysbiosis can lead to inflammatory bowel diseases (IBD) and systemic inflammation, affecting multiple organs. Developing novel anti-inflammatory therapeutics is crucial for preventing IBD progression. Serotonin receptor type 2A (5-HT2A) ligands, including psilocybin (Psi), 4-Acetoxy-N,N-dimethyltryptamine (4-AcO-DMT), and ketanserin (Ket), along with transient...
Psychedelic microdosing is the practice of taking very low doses of psychedelic substances, typically over a longer period of time. The long-term safety of chronic microdosing is relatively uncharacterized, but valvular heart disease (VHD) has been proposed as a potential risk due to activation of the serotonin 5-HT 2B receptor. However, this risk has not yet been comprehensively assessed. This...
