Increased protein synthesis - Similar to clenbuterol, which is commonly used to lose fat while maintaining muscle, ephedrine is a beta(2) agonist. If the conformationsare the same (1R,2R or 1S,2S)then the compound is called pseudoephedrine. Each of the enantiomers of both norephedrine and norpseudoephedrine were stereoselectively prepared from the common, prochiral cyclic sulfamidate imine of racemic 1-hydroxy-1-phenyl-propan-2-one by employing asymmetric transfer hydrogenation (ATH) catalyzed by the well-defined chiral Rh-complexes, (S,S)- or (R,R)-Cp*RhCl(TsDPEN), and HCO2H/Et3N as the hydrogen source. Wiley Online Library.

Re: Ephedrine + prostate probs Quote posted by novamanms I have read on certain boards that people claim that ephedrine increases protein synthesis in the prostatewhen I asked for evidence or if this was DHT related, I got no feedback. (1S, 2S)-Ephedrine, one of the four ephedrine isomers, is a common pharmacological agent; however, it is difficult to synthesize in a stereospecific manner using traditional organic synthesis. Nicotine appears to have a role as a fat burner due to its mechanisms, which for the most part increase adrenaline and then work through beta-adrenergic receptors (the molecular target of ephedrine); this increase in adrenaline mediates the increase in metabolic rate which is significant but short-lived with moderate usage. Data Synthesis No weight loss trials assessed duration of treatment greater than 6 months. Yet ephedrine itself has never been illegal in the United States and is currently available over-the-counter, but in useless small doses in cold medicine. A second synthesis was conducted with l-ephedrine, using the same procedure except that the reaction was not quenched with ammonium chloride. The synthesis entails combining nutmeg with water and distilling and only collecting nutmeg oil distilled during the bracket of 110-115 *C, this extracts the myristicin.

The industrial manufacture of ephedrine in China began in the 1920s, when Merck began marketing and selling the drug as ephetonin. Ephedrine is also a common adulterant or substitute in Ecstacy pills. The most popular method for reducing ephedrine to methamphetamine is similar to the Birch reduction , in that it uses anhydrous ammonia and lithium metal. But it's a very strong oxidising agent and it's in the same proportions that ephedrine. I mean no offense to the poster of that synthesis but it is truly out-dated and easier methods have been discovered. Biological activity of ephedra heterocycles A wide approach for the synthesis of new compounds that possess some kind of biologi‐ cal activity is the cyclization of substituted phenethylamines. Ephedrine’s medical use in the Asian world, particularly in China, is indicated for bronchitis and asthma because it is a bronchodilator. BIOSYNTHETIC CLASSIFICATION OF ALKALOIDS Presented by : M.
