Ephedrine is an aromatic secoamine alkaloid, which is present in a variety of ephedra. Ephedrine exhibits optical isomerism, with two chiral centers, giving rise to four stereoisomers. By convention, the pair of enantiomers with stereochemistry (1R,2S) and (1S,2R) is referred to as ephedrine, while the pair of enantiomers with stereochemistry (1R,2R) and (1S,2S) is referred to as pseudoephedrine.
Ephedrine is widely used in pharmaceutical preparations because of its sweating, asthma, diuretic, anti-inflammatory and other effects.
Molecular structure of ephedrine
Ephedrine can make the coronary arteries, brain, muscle vasodilatation, so that myocardial contraction, increase cardiac output, often causing systolic and diastolic blood pressure rise, pulse pressure increases, but also has a lowering effect of blood viscosity. Ephedrine has an excitatory effect on the respiratory center and an expanding effect on bronchial smooth muscle, but the effect is weak, slow and long-lasting, and has a positive effect on the treatment of asthma and other respiratory diseases. Ephedrine can excite the cerebral cortex and subcortical centers, making people feel mentally excited, even insomnia, etc. Ephedrine can increase the secretion of sweat glands by blocking the reabsorption of sodium from the sweat gland ducts, which has an antipyretic effect on patients with fever. Studies have also shown that ephedrine has antibacterial and antiviral effects on Candida albicans, S. typhi, E. coli, S. dysenteriae, P. aeruginosa, S. diphtheriae, Haemophilus influenzae, B. anthracis, B. streptococci, A. streptococci, S. aureus, influenza A virus PR, Asian influenza A virus, etc.
Creative Proteomics provides qualitative and absolute quantitative analysis of ephedrine through high performance liquid chromatography (HPLC) and high-performance liquid chromatography-mass spectrometry (LC-MS) detection platforms.
