Ayahuasca is a tea with psychoactive properties used by indigenous peoples of South America obtained from the infusion of two plants, Banisteriopsis caapi and Psychotria viridis.From the junction of these plants is obtained a preparation rich in β-carbonyl alkaloids, which promote blockade of Monoaminoxidase (MAO) and considerable concentrations of N, N-dimethyltryptamine (DMT).MAO degrades DMT...

Increasing prevalence and burden of major depressive disorder presents an unavoidable problem for psychiatry. Existing antidepressants exert their effect only after several weeks of continuous treatment. In addition, their serious side effects and ineffectiveness in one-third of patients call for urgent action. Recent advances have given rise to the concept of psychoplastogens. These compounds...

Ketamine, N,N-dimethyltryptamine (DMT), and other psychoplastogens possess enormous potential as neurotherapeutics due to their ability to potently promote neuronal growth. Here, we report the first-ever structure-activity relationship study with the explicit goal of identifying novel psychoplastogens. We have discovered several key features of the psychoplastogenic pharmacophore and used this...

Drug use and the associated overdose deaths have been a serious public health threat in the United States and the world. While traditional drugs of abuse such as cocaine remain popular, recreational use of newer synthetic drugs has continued to increase, but the prevalence of use is likely underestimated. In this review, epidemiology, chemistry, pharmacophysiology, clinical effects, laboratory...

Abstract The regulatory role of the serotonergic system on conscious perception can be investigated perturbatorily with psychedelic drugs such as N,N-Dimethyltryptamine. There is increasing evidence that the serotonergic system gates prior (endogenous) and sensory (exogenous) information in the construction of a conscious experience. Using two generative deep neural networks as examples, we...

Ayahuasca is a psychoactive brew that contains N,N-dimethyltryptamine and monoamine oxidase-inhibiting alkaloids. It is originally from the Amazon rainforest, but since the 1990s it has expanded worldwide. The compound is used in different religious, spiritual, and therapeutic settings. One of its common applications is for the treatment of addiction. The current study is an assessment of the...

Summary We report five cases involving use of 3 Meo-PCP (3 methoxyphencyclidine) with 2 fatalities and 3 non-fatal cases seen in France in 2018. PCP (Phencyclidine) is an arylcyclohexanexylamine, synthesised by Maddox in 1956, and has a potent dissociative anaesthetic drug. One derivative 3 Meo-PCCP appeared on the street market in 2012 with potency slightly lower than PCP. The three non-fatal...

Studying transitions in and out of the altered state of consciousness caused by intravenous (IV) N,N-Dimethyltryptamine (DMT - a fast-acting tryptamine psychedelic) offers a safe and powerful means of advancing knowledge on the neurobiology of conscious states. Here we sought to investigate the effects of IV DMT on the power spectrum and signal diversity of human brain activity (6 female, 7...

Classic or serotonergic hallucinogens comprise the third largest number of reported new psychoactive substances (NPS), according to the United Nations Office on Drugs and Crime. While being structurally very divergent, they share activation of the serotonin 2A receptor (5-HT2AR), a G protein-coupled receptor, as their main pharmacological mechanism. Here, we report on the development of a...

Ayahuasca is a psychoactive beverage prepared traditionally from a mixture of the leaves and stems of Psychotria viridis and Banisteriopsis caapi, respectively, being originally consumed by indigenous Amazonian tribes for ritual and medicinal purposes. Over the years, its use has spread to other populations as a means to personal growth and spiritual connection. Also, the recreational use of...
