Background/Objectives: Psilocibin (PSY), a serotonergic hallucinogen, has attracted increasing scientific interest due to its therapeutic potential, particularly in treatment-resistant depression. In parallel with its growing clinical and research relevance, important questions have emerged regarding its safety profile, including potential effects on the liver, kidneys, cardiovascular system,...
Psychedelics have emerged as a promising novel therapeutic approach for major depressive disorder (MDD). Altered activity and structural atrophy of the prefrontal cortex, hippocampus, and limbic structures are associated with depressive disorders. Psilocybin may reverse the loss of synaptic connections and restore the function of these brain regions. In this study, we investigated the effects...
INTRODUCTION: Psilocybin, a classic serotonergic psychedelic, has antidepressant, anxiolytic, anti-inflammatory, and analgesic properties. However, the immunomodulatory effects of psilocybin within the central nervous system, particularly on microglial activation, remain poorly understood. Therefore, this study aimed to investigate the effects of psilocybin on microglial activation markers and...
Abstract Obsessive-compulsive disorder (OCD) is a chronic mental disease that affects approximately 2% of the population. Obsessions and compulsions are troublesome for patients and may disturb their everyday activities. The pathogenesis of this disease is still not fully elucidated, but dysfunctions of serotonin-, dopamine- and glutamate-mediated neurotransmission together with early...
NBOMes are N-benzylmethoxy derivatives of the 2C family compounds with N-2-methoxybenzyl moiety substituted by the methoxy group at the 2- and 5-position and the halogen group at the 4-position of the phenyl ring. These substances are a new class of potent serotonin 5-HT2A receptor agonist hallucinogens with potential harmful effects. The substitution with halogen of the already psychoactive...
Abstract Purpose N-Methoxybenzyls, a group of toxic phenylethylamine derivatives of the 2C family compounds, are a new class of potent serotonin 5-HT2A receptor agonist hallucinogens with potential harmful effects. This study summarizes current state of knowledge of one of the most dangerous representative of this group—N-(2-methoxybenzyl)-2,5-dimethoxy-4-chlorophenethylamine (25C-NBOMe). Due...
NBOMes are N-benzylmethoxy derivatives of the 2C family hallucinogens. 4-Iodo-2,5-dimethoxy-N-(2-methoxybenzyl)phenethylamine (25I-NBOMe) is one of the commonly used illicit drugs. It exhibits high binding affinity for 5-HT 2A/C and 5-HT 1A serotonin receptors. Activation of 5-HT 2A receptor induces head-twitch response (HTR) in rodents, a behavioral marker of hallucinogen effect in humans....
MDMA (3,4-methylenedioxymethamphetamine) is a psychostimulant popular as a recreational drug because of its effect on mood and social interactions. MDMA acts at dopamine (DA) transporter (DAT) and serotonin (5-HT) transporter (SERT) and is known to induce damage of dopamine and serotonin neurons. MDMA is often ingested with caffeine. Caffeine as a non-selective adenosine A1/A2A receptor...
5-Methoxy-N,N-diisopropyltryptamine (5-MeO-DIPT, 'foxy') is one of the most popular tryptamine hallucinogens in the illicit drug market. It produces serious adverse effects, but its pharmacological profile is not well recognized. In vitro data have shown that 5-MeO-DIPT acts as a potent serotonin transporter (SERT) inhibitor and displays high affinity at serotonin 5-HT1A, 5-HT2A, and 5-HT2C...
New psychoactive “designer drugs” are synthetic compounds developed to provide similar effects to illicit drugs of abuse, but not subjected to legal control. The rapidly changing legal status of novel psychoactive drugs triggers the development of new compounds, analogs of well-known amphetamine or mescaline. New designer drugs used as substitutes in ecstasy pills are the least investigated and...
