Determination of Enantiomers of Deschloroketamine and Its Metabolites in Wistar Rat Brains

Journal of Separation Science, Volume 49, Issue 9, September 2026.
Although supercritical fluid chromatography coupled to mass spectrometry efficiently resolved deschlorketamine and its metabolites, the parent drug must have been quantified by capillary zone electrophoresis. ABSTRACT Deschloroketamine (DXE) is a dissociative new psychoactive substance whose enantiomers and metabolites may exhibit distinct ...

New psychoactive substances : cathinone and its derivatives [PDF]

, 2019
Cathinone is the major alkaloid found in the Catha edulis plant. The chemical structure of the cathinone is similar to amphetamine, and the difference in their structure is the presence of the ketone group in the beta side chain position.

Dopamine Concentration Changes Associated with the Retrodialysis of Methylone and 3,4-Methylenedioxypyrovalerone (MDPV) into the Caudate Putamen

Brain Sciences
Structural modifications to synthetic psychoactive cathinones (SPCs), a class of drugs that contain a β-keto modification of the phenethylamine pharmacophore of amphetamine, induce differences in dopamine transporter (DAT) activity.

Detection of cathinone and mephedrone in plasma by LC-MS/MS using standard addition quantification technique

Journal of Analytical Science and Technology, 2017
Background Cathinones better known as bath salts have been listed as illicit drugs since 2011. Few studies have focused on the analytical extraction techniques and the matrix effect affecting their detection and quantification in biological samples ...

Polymorphism vs. Aromaticity in Cathinone Derivative 2-Amino-1-(4-Bromo-2,5-Dimethoxyphenyl)Ethan-1-One (bk-2C-B)

Crystals
Cathinone and its synthetic derivatives are one of the most commonly used narcotics in the world. Some studies describe their antidepressant and smoking cessation potential, as well as cytostatic activity on several cancer cell lines.

Role of instrumental learning in tolerance to cathinone hypophagia

, 2006
The effects of dl-cathinone on milk intake and motor activity were investigated in bottle- and cannula-fed rats. Acute injections of cathinone produced dose-dependent increases in activity in both groups but only produced decreased intake in bottle-fed ...

On 3‐MMC: A Cathinone I Have Come to Know and Love

Anthropology of Consciousness, Volume 37, Issue 2, Fall 2026.
ABSTRACT This article attempts to complicate the mythology of a compound in a state of becoming. I will trace lightly its origins as a cultural disruptor and how I am implicated in this imperative. Introducing you to 3‐MMC will require multiple modes of storytelling and taking of liberties, drawing on literature reviews, practice‐based research, prose,

Cyclodextrins as Chiral Selectors in Capillary Electrophoresis—Recent Developments in Understanding Analyte Complexation and Applications in Pharmaceutical Analysis

ELECTROPHORESIS, Volume 47, Issue 8, Page 696-712, August 2026.
Cyclodextrins are the most often applied chiral selectors in CE enantioseparations. In combination with NMR spectroscopy and molecular modeling, studies for an understanding of chiral recognition underlying enantioseparations have been performed.

Forensic implications of novel synthesis of cathinone derivatives by Neber and modified Neber rearrangements

Cathinone and its synthetic analogues are known compounds of clandestine interest. Investigation into novel pathways for synthesising cathinone derivatives has potential for forensic analysis and tracking.

Cathinone increases body temperature, enhances locomotor activity, and induces striatal c-fos expression in the Siberian hamster

, 2014
Cathinone is a β-keto alkaloid that is the major active constituent of khat, the leaf of the Catha edulis plant that is chewed recreationally in East Africa and the Middle East. Related compounds, such as methcathinone and mephedrone have been increasing
