Death-cap mushroom toxin synthesized

C&EN Global Enterprise, 2018
α-Amanitin, a bicyclic octapeptide produced by the death-cap mushroom, is one of the deadliest known peptide toxins. Researchers are exploring antibody-drug conjugates of it as possible anticancer agents. “α-Amanitin has been the subject of thousands of published studies due to its exceptional toxicity,” says Steven L.

Rifampicin and cysteamine protect against the mushroom toxin phalloidin

Experientia, 1974
Der Schutzefekt von Rifampicin gegen eine Letaldosis des Pilzgiftes Phalloidin wurde bestatigt und weiter charakterisiert. Auch Cysteamin erwies sich als wirksam. Keinen Schutz gegen Phalloidin boten Stoffe, welche das Pilzgift α-Amanitin antagonisieren. Die hepatotoxische Wirkungskomponente der meisten Phalloidin-Antagonisten wird erortert.

Ribosomally Encoded Cyclic Peptide Toxins from Mushrooms

2012
The cyclic peptide toxins of poisonous Amanita mushrooms are chemically unique among known natural products. Furthermore, they differ from other fungal cyclic peptides in being synthesized on ribosomes instead of by nonribosomal peptide synthetases. Because of their novel structures and biogenic origins, elucidation of the biosynthetic pathway of the ...

[Amanita phalloides toxins in dried mushrooms].

Casopis lekaru ceskych, 1993
The content of toxins from Amanita phalloides in dried carpophores is decreasing in the dependence on time. The content of alpha-amanitin found after 20 years was about one half. A mere trace of alpha-amanitin which is the most stable of all toxins was detected in a carpophore 50 years old. Degradation of amatoxins and phallotoxins by light (mainly the

Toxins and Psychoactive Compounds from Mushrooms

1996
This chapter describes the toxic and/or hallucinogenic components of mushrooms obtained in pure form and chemically characterized up to now. Attempts to isolate the poisonous alkaloid of a fungus, the red fly agaric Amanita muscaria, were made almost 130 years ago.

[Hallucinogenic psilocybine containing mushrooms. Toxins contained in Danish wild mushrooms].

Ugeskrift for laeger, 1990
A number of the wild Danish mushrooms contain the hallucinogenic agent psilocybin which resembles LSD in many ways. The commonest of these are the "liberty cap" or "magic mushrooms" (Psilocybe semilanceata). On the basis of experience from USA and western Europa, increase in employment of this mushrooms as a hallucinogenic intoxicant may be anticipated

ANTIOXIDANT PROPERTIES OF AMANITA PHALLOIDES MUSHROOM TOXINS

2004
Alpha amanitin and phalloidin are powerful hepatotoxins that belong to the main classes of toxins namely, amatoxins and phallotoxins, isolated from the deadly poisonous mushroom Amanita phalloides. It is well known that disruptions of antioxidant enzyme defense that include superoxide dismutase (SOD), catalase, glutathione peroxidase lead to generation
