Cyclodextrin-Enabled Enantioselective Complexation Study of Cathinone Analogs

Molecules
The characteristic alkaloid component of the leaves of the catnip shrub (Catha edulis) is cathinone, and its synthetic analogs form a major group of recreational drugs. Cathinone derivatives are chiral compounds. In the literature, several chiral methods

MECHANISM OF ACTION OF (−)CATHINONE, A NEW ALKALOID FROM KHAT LEAVES [PDF]

, 2017
A new alkaloid, (−)cathinone, has recently been isolated from khat leaves and has been shown to induce amphetamine-like behavioural effects. The actions of this alkaloid at the cellular level are discussed here and it is concluded that (−)cathinone ...

Elucidation of the metabolites of the novel psychoactive substance 4-methyl-N-ethyl-cathinone (4-MEC) in human urine and pooled liver microsomes by GC-MS & LC-HR-MS/MS techniques and of its detectability by GC-MS or LC-MS(n) standard screening approaches [PDF]

, 2014
4-methyl-N-ethcathinone (4-MEC), the N-ethyl homologue of mephedrone, is a novel psychoactive substance of the beta-keto amphetamine (cathinone) group. The aim of the present work was to study the phase I and phase II metabolism of 4-MEC in human urine ...

Psychopathological Concomitants and Motivations Related to Misuse of Non‐Steroidal Anti‐Inflammatory Drugs and Paracetamol

Human Psychopharmacology: Clinical and Experimental, Volume 41, Issue 3, May 2026.
ABSTRACT Introduction Non‐steroidal anti‐inflammatory drugs (NSAIDs) and paracetamol are among the most commonly used medications worldwide. It has been suggested that the misuse of such medications is not uncommon. The objective of the present research was to explore prevalence, reported reasons and psychopathological concomitants related to NSAIDs ...

RECENT ADVANCES IN KHAT RESEARCH [PDF]

, 2017
Khat leaves are widely used as a stimulant in East Africa and the Arabian Peninsula and the effect of the material was formerly believed to be due to its content of norpseudoephed-rine. Recently, however, a new alkaloid, cathinone, has been discovered in

Analytical Challenges in Detecting New Psychoactive Substances in Anti‐Doping: A Proof‐of‐Concept Involving Pentedrone Metabolite

Drug Testing and Analysis, Volume 18, Issue 4, Page 530-536, April 2026.
The paper describes an investigation related to the pentedrone norephedrine metabolite. The athlete's sample was analyzed using ultra‐performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS). According to the literature, this metabolite may originate from pentedrone, α‐pyrrolidinopentiophenone (PVP), or N‐ethylpentedrone (NEP).
