Preparation and evaluation of molecularly imprinted polymer liquid chromatography column for the separation of Cathine enantiomers [PDF]
Saudi Pharmaceutical Journal, 2012 In this study molecular imprinting technology was employed to prepare a specific affinity sorbent for the resolution of Cathine, a chiral drug product. The molecularly imprinted polymer (MIP) was prepared by non-covalent molecular imprinting with either (

Chirality, 2023
AbstractIn the current work, an enantioselective imprinting technique was used to develop a very selective adsorbent for the (+)‐cathine ((+)‐Cat) enantiomer. The phenolic sulfonamide produced from 2,4‐dihydroxybenzenesulfonic acid (HBS) and (+)‐Cat ((+)‐Cat‐HBS) was initially synthesized by triphenylphosphene activation and subsequently involved in ...

Determination of cathinone and cathine in Khat plant material by LC–MS/MS: Fresh vs. dried leaves
Forensic Science International, 2021The consumption of Khat leaves represents an ancient kind of drug abuse mainly observed in Eastern Africa and the Arab Peninsula among adult men. For this purpose, the leaves are directly collected from the shrub "Catha edulis" prior to extensive chewing process.

Rats become acutely tolerant to cathine after amphetamine or cathinone administration
Psychopharmacology, 1990The drug discrimination paradigm was used to evaluate in rats the ability of the discriminate response to either 0.8 mg/kg d-amphetamine or 0.8 mg/kg l-cathinone to generalize to 2.4-6.0 mg/kg of the active cathinone metabolite d-norpseudoephedrine, also known as cathine.

A GC-MS Method for Detection and Quantification of Cathine, Cathinone, Methcathinone and Ephedrine in Oral Fluid. [PDF]
Journal of Chromatographic Science, 2016 The stimulating herbal drug khat (cathine, cathinone) and its analog methcathinone are common substances of abuse in most countries. A GC-MS method was developed and validated for the detection and quantification of cathine, cathinone, methcathinone and ephedrine in oral fluid specimens.

Biochemical effects of Catha edulis, cathine and cathinone on adrenocortical functions
Journal of Ethnopharmacology, 1993Catha edulis is a plant that grows in certain areas of East Africa and the Arab Peninsula. The stimulating properties of fresh material were described more than seven centuries ago and today the habit of inducing a state of euphoria and subjective well-being by chewing Catha edulis prevails among the inhabitants of these regions. Oral administration of

The stimulant cathine from Khat causes tachycardia indirectly in the rat
Basic and Clinical Pharmacology and ToxicologyAbstractLeaves of the Khat plant are widely consumed in the Horn of Africa, Yemen and the Jazan region of Saudi Arabia. I have investigated the mode of cardiovascular and autonomic actions of the stimulant cathine from Khat in terms of direct or indirect adrenergic actions in anaesthetised male and female rats, and in isolated tissues.

Determination of cathinone, cathine and norephedrine in hair of Yemenite khat chewers
Forensic Science International, 2003A sensitive and reproducible method for the quantitative determination of cathinone (CTN), norpseudoephedrine (NPE, cathine) and norephedrine (NE) from hair was developed. The compounds were extracted for 4 hours with phosphate buffer pH 2.0, followed by a standard solid phase extraction procedure on a mixed phase column, derivatization with ...

Kathsträucher, Cathin, Cathinon, Suchtgift, psychotroper Stoff
Journal für Strafrecht, 2020Das in den Zweigspitzen und jungen Blattern von Kathstrauchern enthaltene Cathin ist ein psychotroper Stoff iS des SMG, das darin enthaltene Cathinon ist ein Suchtgift iS des SMG. Die Einfuhr von Kathstrauchern verwirklicht daher die Vergehen gem § 30 Abs 1 5. Fall (bzw § 31a Abs 1 2. Fall) SMG und § 27 Abs 1 Z 1 5. Fall (bzw § 28a Abs 1 1. Fall) SMG.
