  2. Ephedrine - Wikipedia

    en.wikipedia.org/wiki/Ephedrine

    Ephedrine works by inducing the release of norepinephrine and hence indirectly activating the α-and β-adrenergic receptors. [11] Chemically, ephedrine is a substituted amphetamine and is the (1R,2S)-enantiomer of β-hydroxy-N-methylamphetamine. [14] Ephedrine was first isolated in 1885 and came into commercial use in 1926.

  3. Amphetamine type stimulant - Wikipedia

    en.wikipedia.org/wiki/Amphetamine_type_stimulant

    Ephedrine is the precursor of synthetic amphetamines. The diastereomer of ephedrine, pseudoephedrine is found in Ephedra sinica together along with ephedrine. Ephedrine and pseudoephedrine are both generally used for weight reduction and performance enhancement. They can also be reduced to methamphetamine. [2]

  4. ECA stack - Wikipedia

    en.wikipedia.org/wiki/ECA_stack

    The ECA stack is a drug combination used in weight loss and as a stimulant.ECA is an initialism for ephedrine, caffeine, and aspirin, with variants of it including the EC stack, which removes the aspirin for those who can not tolerate it.

  5. History and culture of substituted amphetamines - Wikipedia

    Pseudoephedrine, ephedrine, phenylacetone, and phenylacetic acid are currently DEA list I, and acetic anhydride is list II on the DEA list of chemicals subject to regulation and control measures. This method can involve the use of mercuric chloride and leaves behind mercury and lead environmental wastes. [ 101 ]

  6. Precursor chemicals - Wikipedia

    en.wikipedia.org/wiki/Precursor_chemicals

    Drug precursors, also referred to as precursor chemicals or simply precursors, are substances used to manufacture illicit drugs. Most precursors also have legitimate commercial uses and are legally used in a wide variety of industrial processes and consumer products, such as medicines, flavourings, and fragrances.

  7. Alkaloid - Wikipedia

    en.wikipedia.org/wiki/Alkaloid

    Biological precursors of most alkaloids are amino acids, such as ornithine, lysine, phenylalanine, tyrosine, tryptophan, histidine, aspartic acid, and anthranilic acid. [188] Nicotinic acid can be synthesized from tryptophan or aspartic acid. Ways of alkaloid biosynthesis are too numerous and cannot be easily classified. [85]

  9. 4-Fluoroephedrine - Wikipedia

    en.wikipedia.org/wiki/4-Fluoroephedrine

    [6] [1] It is the 4-fluoro analogue of ephedrine. [6] [1] The synthesis of 4-fluoroephedrine has been described. [7] It can serve as a precursor in the synthesis of 4-fluoromethamphetamine (4-FMA). [3] The predicted log P of 4-fluoroephedrine is 1.0. [6] For comparison, the predicted log P of ephedrine is 0.9.
