Common NameL-Coprine
ClassSmall Molecule
DescriptionL-Coprine is found in mushrooms. L-Coprine is present in the moderately toxic ink cap mushroom Coprinus atramentarius (common ink cap). Produces an oversensitivity to ethanol in some people. L-Coprine belongs to the family of Alpha Amino Acids and Derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon)[1]. (Reference: [1] Amino Acid:

Chemical Taxonomy
Description belongs to the class of organic compounds known as glutamine and derivatives. Glutamine and derivatives are compounds containing glutamine or a derivative thereof resulting from reaction of glutamine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom.

Toxicity Profile
Route of ExposureOral, dermal, inhalation, and parenteral (contaminated drugs). (1)
Mechanism of ToxicityIt metabolises to 1-aminocyclopropanol, a closely-related chemical to Disulfiram and exhibits the same mechanism of action: inhibition of the enzyme acetaldehyde dehydrogenase, which is required for alchohol metabolism. (3)
MetabolismMetabolises to 1-aminocyclopropanol. (3)
Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesCoprine occurs naturally in the otherwise edible mushroom, the common ink cap (Coprinopsis atramentaria). (3)
Minimum Risk LevelNot Available
Health EffectsCoprine interferes with the bodys ability to metabolize alcohol. This causes the build of of acetaldehyde in the body. (4)
SymptomsCoprine may cause symptoms such as flushing, headache, nausea, palpitations, dyspnea, dizziness. (4)
