• Structure-toxicity relationships in the amatoxin series. (mpg.de)
  • If the gastrointestinal distress begins 6 to 24 hours after ingestion of the mushrooms, there is a possibility of a very serious toxicity from Amatoxins (see Amanitin). (namyco.org)
  • Cyclopeptides include amatoxins (high toxicity), phallotoxins (medium toxicity), and virotoxins (no toxicity). (medscape.com)
  • It is part of a group of toxins called amatoxins, which can be found in several mushrooms belonging to the genus Amanita. (wikipedia.org)
  • Amatoxins, gyromitrins, and orellanine are the toxins most commonly implicated in fatal mushroom poisonings worldwide. (medscape.com)
  • Synthesis of analogues of amaninamide, an amatoxin from the white Amanita virosa mushroom. (mpg.de)
  • All of the mushrooms that contain ibotenic acid and muscimol also sometimes contain muscarine (a toxin that got the name muscarine because it was first isolated from Amanita muscaria in the late 1800s). (namyco.org)
  • Amatoxins, which are responsible for more than 95% of mushroom-related fatalities in the United States, are cyclic octapeptides that are synthesized by some Amanita , Galerina, and Lepiota species (see the list below). (medscape.com)
  • Atropine is NOT indicated in cases of poisoning by ibotenic acid or muscimol. (namyco.org)
  • Thus, patients sometimes also suffer muscarinic symptoms as well as symptoms of ibotenic acid and muscimol poisoning. (namyco.org)
  • However, atropine's effects are close to those of ibotenic acid and its use is likely to exacerbate symptoms. (namyco.org)
  • GI onset of 4-11 hours with impaired kidney function could be due to Allenic Norleucine (2-amino-4,5-hexadienoic acid). (namyco.org)
