Psilocybin is a serotonergic 5-HT 2A R agonist that causes psychedelic and anxiolytic effects in human users. To delineate conservation of psilocybin pharmacology, we investigated behavioral effects of psilocybin in planarians ( Dugesia dorotocephala ), the simplest living animal with cephalization that also has a well defined serotonin (5-hydroxytryptamine [5-HT]) system. We quantified...
Psilocybin is found in a family of mushrooms commonly known as Psilocybe. We aimed to study the antinociceptive efficacy of psilocybin using formalin-induced noxious stimuli, a model that comprises both acute and persistent pain in rats. Adult male Sprague–Dawley rats were used. Psilocybin (0.1, 0.3, and 1 mg/kg, IP) or vehicle was administered, and 6 h later, formalin (5%, 50 µL, subcutaneous)...

Cathinone is a plant alkaloid found in khat leaves of perennial shrubs grown in East Africa. Similar to cocaine, cathinone elicits psychostimulant effects which are in part attributed to its amphetamine-like structure. Around 2010, home laboratories began altering the parent structure of cathinone to synthesize derivatives with mechanisms of action, potencies, and pharmacokinetics permitting...
BACKGROUND AND PURPOSE: Synthetic cathinones, commonly referred to as 'bath salts', are a group of amphetamine-like drugs gaining popularity worldwide. 4-Methylmethcathinone (mephedrone, MEPH) is the most commonly abused synthetic cathinone in the UK, and exerts its effects by acting as a substrate-type releaser at monoamine transporters. Similar to other cathinone-related compounds, MEPH has a...
Salvinorin (Sal) A is a naturally occurring, selective kappa opioid receptor (KOPR) agonist with a short duration of action in vivo. Pharmacological properties of a C(2) derivative, 2-methoxymethyl (MOM)-Sal B, were characterized. MOM-Sal B bound to KOPR with high selectivity and displayed approximately 3-fold higher affinity than U50,488H...
