Introduction: The effects of the endogenous hallucinogen N,N-dimethyltryptamine are poorly understood and its medical significance is widely unknown. A small number of studies regarding its biochemical, pharmaceutical and physiological role have been conducted and the efficacy of its therapeutic potential is presently disregarded. How can scientists proceed in gaining insight into DMT and...
Psychotria viridis is one of the species that produces N,N-dimethyltryptamine. Its decoction \ntogether with other species, such as Banisteriopsis caapi, produces ayahuasca, a beverage used for \nritualistic and medicinal purposes. The goal of this study was to understand how environmental \nfactors and cultivation methods influenced the content of N,N-dimethyltryptamine in P. viridis. \nOver...
N,N-dimethyltryptamine (DMT) is a potent endogenous hallucinogen present in the brain of humans and other mammals. Despite extensive research, its physiological role remains largely unknown. Recently, DMT has been found to activate the sigma-1 receptor (Sig-1R), an intracellular chaperone fulfilling an interface role between the endoplasmic reticulum (ER) and mitochondria. It ensures the...
N,N-DMT molecule is known in many cultures as endogenous hallucinogen and most research has been directed towards the psychological effects or structural definition while molecular interactions in conditions of the human body are poorly understood. We have complemented past structural research of N,N-DMT and investigated molecular interactions of N,N-DMT in the environment of 0.1 M hydrochloric...
5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT) and harmaline are indolealkylamine (IAA) drugs often abused together. Our recent studies have revealed the significant effects of co-administered harmaline, a monoamine oxidase inhibitor (MAOI), on 5-MeO-DMT pharmacokinetics and thermoregulation. This study was to delineate the impact of harmaline and 5-MeO-DMT on home-cage activity in mouse models,...
N,N-dimethyltryptamine (DMT) is an indole alkaloid widely found in plants and animals. It is best known for producing brief and intense psychedelic effects when ingested. Increasing evidence suggests that endogenous DMT plays important roles for a number of processes in the periphery and central nervous system, and may act as a neurotransmitter. This paper reviews the current literature of both...
Monoamine oxidase inhibitors (MAOIs) are often ingested together with tryptamine hallucinogens, but relatively little is known about the consequences of their combined use. We have shown previously that monoamine oxidase-A (MAO-A) inhibitors alter the locomotor profile of the hallucinogen 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) in rats, and enhance its interaction with 5-HT2A receptors....
5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT) is a natural hallucinogen, acting as a non-selective serotonin 5-HT(1A)/5-HT(2A)-R agonist. Psychotomimetic agents such as the non-competitive NMDA-R antagonist phencyclidine and serotonergic hallucinogens (DOI and 5-MeO-DMT) disrupt cortical synchrony in the low frequency range (<4 Hz) in rat prefrontal cortex (PFC), an effect reversed by...
The inflammatory theory of many neuropsychiatric illnesses has become an emerging trend in modern medicine. Various immune mechanisms – mainly via the activity of microglia – may contribute to the etiology and symptomatology of diseases, such as schizophrenia, bipolar disorder, depression, or Alzheimer's disease (Deleidi et al. , 2015; Khandaker et al. , 2015). Unwanted and excess inflammation...
The state of consciousness induced by N,N-dimethyltryptamine (DMT) is one of the most extraordinary of any naturally-occurring psychedelic substance. Users consistently report the complete replacement of normal subjective experience with a novel "alternate universe," often densely populated with a variety of strange objects and other highly complex visual content, including what appear to be...
