The therapeutic potential of low, non-psychedelic doses of psilocybin, a fungal tryptamine alkaloid, was investigated in metabolic disorders including obesity, type 2 diabetes mellitus (T2DM), and liver steatosis. Mice fed a high-fat/high-fructose diet received chronic treatment with psilocybin (0.05 mg/kg) for 12 weeks. Body weight, liver histology, insulin sensitivity, and skeletal muscle...
BPL-003 is a novel investigational psychedelic compound being developed for the treatment-resistant depression (TRD). Its active ingredient, 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT), is a serotonergic psychedelic with preferential agonism at 5-HT1A receptors and rapid pharmacokinetics, allowing for a brief, supervised in-clinic administration. Preclinical studies demonstrate that 5-MeO-DMT...
) that has a unique therapeutic potential across multiple indications, including opioid dependence, substance use disorders, depression, anxiety, posttraumatic stress disorder (PTSD), and traumatic brain injury (TBI). We systematically examined the effects of ibogaine, its main metabolite noribogaine, and a series of iboga analogs at monoamine neurotransmitter transporters, some of which have...
Dear Editor, In view of ongoing global research on mental health, especially Major Depressive Disorder, we would like to draw attention to a psychedelic substance, Psilocybin, which has been emerging as a viable treatment option for MDD. Psilocybin is a psychedelic compound derived from certain mushrooms that acts on Serotonergic receptors (primarily 5HT-2A). Psychedelic substances have...
N,N-Dimethyltryptamine (DMT) is a serotonergic psychedelic that is being investigated for the treatment of psychiatric disorders. Although the neurophysiological effects of DMT in humans are well characterized, similar studies in animal models and data on the neurochemical effects of DMT are generally lacking, which are critical for a mechanistic understanding. Here, we combined behavioral...
α-Ethyltryptamine (AET), a synthetic tryptamine formerly used as an antidepressant, has resurfaced as a compound of interest due to its structural and functional overlap with serotonergic psychedelics and entactogens. Here, we characterized the pharmacological properties of racemic AET and its optical isomers, R(-)-AET and S(+)-AET, focusing on their interactions with the serotonin (or...
A light-induced cyclization via a radical spin-center shift process that results in the direct functionalization of the indole ring at the C4-position is developed into a practical method for the synthesis of medicinally active, ring-constrained tryptamine analogs. Amino acids were coupled to tryptamine and irradiated with UV light to produce a library of lactams bridging the C3- and...
Classical psychedelics, like lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT), and psilocybin, can alter perception, emotion, and cognition, and have shown promise as 're-purposed' treatments for some psychiatric disorders. Recent trials have, e.g., demonstrated rapid and sustained symptom relief in treatment-resistant depression. While promising as a treatment, the...
Following decades of prohibition, psychedelic drugs have reemerged as promising therapeutics for stress-related conditions, including depression and post-traumatic stress disorder. Still, their impact on stress-related brain regions and the hypothalamic-pituitary-adrenal (HPA) axis remains unclear. This work explores the acute effects of psilocybin on the primary regulators of the HPA axis:...
Psilocybin, psilocin and the associated tryptamines are psychoactive alkaloids which are naturally biosynthesised by Psilocybe (Fr.) P.Kumm. fungi, commonly referred to as magic mushrooms. These psychoactive fungi were used traditionally in healing rituals, and are now being studied in clinical studies to investigate their benefits as a treatment for a number of mental health disorders. Since...
Psychedelics are gaining recognition for their effectiveness as modulators of neuroplasticity in the treatment of a range of neuropsychiatric disorders. Psilocybin, lysergic acid diethylamide, N,N-dimethyltryptamine, and ketamine are substances that mainly affect the serotonergic and glutamatergic systems. They induce rapid synaptogenesis, dendritic remodeling, and changes in functional...
3,4-Methylenedioxymethamphetamine (MDMA), commonly known as ecstasy, shows promise in treating depression and post-traumatic stress disorder (PTSD), resulting in breakthrough status. However, concerns regarding MDMA's abuse potential and cytotoxicity have sparked interest in developing safer analogues with similar therapeutic benefits. This study investigated the pharmacological properties of...
ABSTRACT The psychedelic psilocybin has gained popularity in recent years as a therapy for treatment‐resistant depression and has been reported to reduce symptoms of depression and anxiety. Psilocybin's active metabolite, psilocin, possesses a binding affinity for serotonin receptors as well as for the serotonin transporter (5‐HTT). We recently reported that in contrast to wild‐type mice,...
Depression is a debilitating mental disorder affecting millions worldwide, yet current pharmacological treatments, such as selective serotonin reuptake inhibitors (SSRIs), often exhibit delayed onset and limited efficacy. The chronic social defeat (CSD) stress model in mice is a well-established preclinical paradigm for inducing depression-like behaviors and evaluating antidepressants...
AIM: The regulation of new psychoactive and dangerous abused substances is very important for the prevention of drug abuse. A simple and effective evaluation method using laboratory animals is needed to regulate designated drugs with high accuracy and speed. METHODS: receptor agonist 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane hydrochloride (DOI), which have a similar mechanism of action to...
3,4-Methylenedioxymethamphetamine (MDMA), commonly known as ecstasy, is a psychostimulant with entactogenic properties and known to induce arousal and euphoria. As an amphetamine derivate, MDMA acts on the monoamine systems in the brain and stimulates release of dopamine (DA), noradrenaline (NA) and serotonin (5-HT), yet their individual contributions in driving arousal and euphoria remain...
Emerging evidence suggests that classical psychedelics may offer therapeutic potential for opioid use disorder (OUD) by alleviating key hallmarks such as altered reward processing and dependence. However, the mechanisms behind these effects remain unclear. Our data demonstrate that a single administration of the psychedelic psilocybin (PSI) reduces conditioned behavior and withdrawal induced by...
Psychedelics have garnered significant interest for their therapeutic potential in mental health conditions such as depression, anxiety, and post-traumatic stress disorder. While research has primarily focused on well-studied psychedelics, phenethylamine derivatives have also gathered interest for their potential therapeutic applications. Thus, this study aims to investigate the pharmacological...
This study evaluated the effects of ibogalogs on recognition and spatial memory in rodents, focusing on potential hippocampal mechanisms. The Barnes maze study demonstrated that ibogaminalog (DM506) and ibogainalog (IBG) improved short- (30 min) and long-term (24 and 72 h) spatial memory in mice, whereas tabernanthalog (TBG) showed less efficacy. The novel object recognition task (NORT) results...
