In der gegenwärtigen Arbeit wurden die Strukturvielfalt und die genetischen und enzymatischen Grundlagen der Indolalkaloidbiosynthese in Basidiomyceten in Psilocybe spp. untersucht. Durch in silico-Analysen und heterologe Expression ist es gelungen, die Biosynthese des Psilocybins aufzuklären, die verantwortlichen Gene zu identifizieren und die resultierenden Enzyme biochemisch und...
Abstract Abstract Research has shown that psychedelics, such as lysergic acid diethylamide (LSD), have profound anti-inflammatory properties mediated by 5-HT 2A receptor signaling, supporting their evaluation as a therapeutic for neuroinflammation associated with neurodegenerative disease. Objective This study evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamics of orally...
Background: Depression is the neuropsychiatric disorder that can lead to the disruption of brain nerves by elevating different mechanisms and neurotransmitters such as serotonin, noradrenaline, dopamine. It can have a series of episodic events that can cross one episodic depression to another and manifest various symptoms such as agitation, melancholia, deep sadness, psychomotor retardation,...
\n Alucinógenos (ALU) são substâncias psicoativas que não induzem o indivíduo à dependência, possuem perfil de segurança de uso mais alto quando comparado a outras drogas e baixa capacidade de causar tolerância ao uso. Estudos recentes propõem o uso de ALU como tratamento a algumas doenças e transtornos relacionados ao sistema nervoso central, como a depressão, ansiedade e dependência. Dentre...
Objective: N-(2-methoxy) benzyl-phenethylamine (NBOMe) derivatives have a high affinity to the serotonin receptor 2A and emerged as new psychedelic agents. We report the case of a 30-year-old man admitted to the hospital because of acute ischemia of the left arm with clinical symptoms of pallor, pulselessness, paresthesia, and a motoric deficit. The patient had a history of schizophrenia and...
-fenfluramine, a selective serotonin-releasing compound. By dissociating the mechanisms of MDMA's prosocial effects from its addictive properties, we provide evidence for a conserved neuronal pathway, which can be leveraged to develop novel therapeutics with limited abuse liability.
Visual hallucinations (VH) are commonly found in the course of synucleinopathies like Parkinson's disease and dementia with Lewy bodies. The incidence of VH in these conditions is so high that the absence of VH in the course of the disease should raise questions about the diagnosis. VH may take the form of early and simple phenomena or appear with late and complex presentations that include...
As a continual source of sensory input and fundamental component of self-referential processing, the body holds an integral modulatory role in cognition. In a healthy state, predictive coding of multisensory integration promotes the construction of a coherent self. However, several psychiatric disorders comprise aberrant perceptions of the bodily self that are purported to involve discrepancies...
MDMA (3,4-methylendioxymethamphetamine), also known as Ecstasy, is a stimulant drug recreationally used by young adults usually in dance clubs and raves. Acute MDMA administration increases serotonin, dopamine and noradrenaline by reversing the action of the monoamine transporters. In this work, we review the studies carried out over the last 30 years on the neuropsychobiological effects of...
N-Benzylphenethylamines, commonly known as NBOMes, are synthetic psychedelic compounds derived from the phenethylamine class of psychedelics (2C-X compounds), which originally have been derived from the naturally occurring alkaloid mescaline. Analogously to their parent compounds and other classical psychedelics, such as psilocybin and lysergic acid diethylamide (LSD), NBOMes are believed to...
