L-Norpseudoephedrine, or (−)-norpseudoephedrine, less commonly known as (–)-cathine or L-cathine, is a psychostimulant drug of the amphetamine family. It is the levorotary isomer of Norpseudoephedrine and is one of the 4 optical isomers of phenylpropanolamine ^[1] ((−)-norpseudoephedrine, (+)-norpseudoephedrine, (−)-norephedrine, & (+)-norephedrine). L-Norpseudoephedrine is an alkaloid of Ephedra sinica, Ephedra equisetina, and Catha edulis (khat). In khat, L-norpseudoephedrine is a secondary alkaloid present alongside cathinone. It is likely responsible for some of the milder stimulant effects of the plant, while cathinone produces the stronger psychoactive effects. In the Ephedra genus, L-norpseudoephedrine is a trace alkaloid compared to the more abundant alkaloids ephedrine and pseudoephedrine. Unlike in khat, L-Norpseudoephedrine does not contribute significantly to the pharmacological actions of Ephedra, as the amount contained in stems/leaves is negligible. L-Norpseudoephedrine is a modestly selective or preferential norepinephrine releasing agent, similarly to other related compounds like ephedrine and pseudoephedrine. It acts as a releasing agent of norepinephrine (EC₅₀ = 30 nM) and to a lesser extent of dopamine (EC₅₀ = 294 nM).^[2] L-Norpseudoephedrine is not classified as a norepinephrine–dopamine releasing agent because of its minimal dopaminergic action and the peripheral predominance of its sympathomimetic effects. In Germany, norpseudoephedrine is used as an alternate name to cathine, a derivative of cathinone, and is only available by prescription.

• AI Overview

  L-Norpseudoephedrine (CAS 37577-07-4), also known as cathine, is a psychostimulant and a highly regulated substance. In many jurisdictions, it is classified as a controlled substance or a precursor chemical (such as a DEA List I chemical in the United States). Due to its regulated status and potential for misuse in the illicit manufacture of controlled substances, providing assistance or specific sources for its purchase is not possible.

   

  Information regarding the legal acquisition of such compounds for legitimate research or medical purposes should be sought through official regulatory bodies or authorized institutional procurement channels that comply with local and international laws.
