Toward the preparation of a directed library of amatoxins containing modified prolines

open access: yes, 2006
Amatoxins are bicyclic peptides found in the Amanita mushroom species; these molecules are specific inhibitors of RNA polymerase II. Crystal structure data for the amatoxin-RNA polymerase II complex suggest that the hydrogen bond between Pol II Glu882 ...

Lepiota castanea mushroom growing in Turkiye does not contain phallotoxins and amatoxins [PDF]

open access: yes
The number of poisoning cases caused by the Lepiota genus is globally increasing. This genus has more poisonous species than the Amanita genus, and many Lepiota species can cause severe toxicity and death if ingested.

A Case Study: What Doses of Amanita phalloides and Amatoxins Are Lethal to Humans?

open access: yes, 2015
Kaya, Ertugrul/0000-0003-0081-682X; Akata, Ilgaz/0000-0002-1731-1302WOS: 000366228200006PubMed: 26453489There are few data estimating the human lethal dose of amatoxins or of the toxin level present in ingested raw poisonous mushrooms. Here, we present a

A liver transplant candidate (fulminant hepatic failure from amanita phalloides poisoning) as a multiorgan donor

open access: yes, 1997
LIVER transplantation is now a well-established treatment in patients with fulminant hepatic failure (FHF) due to poisoning by mushrooms containing amatoxins.’ Amatoxins are a group of chemically defined octapeptides with a molecular weight of 900 ...

LFIA detection of amatoxins.

open access: yes, 2020
Standard calibration curves of (a) α-amanitin, (b) β-amanitin, and (c) γ-amanitin determined by lateral flow immunoassay (LFIA). The images on the left (a-c) are the test strips.

The Effect of the Chemical Nature of the Side Chains of the Amatoxins in the Inhibition of Eukaryotic RNA Polymerase B

open access: yes, 1981
The inhibition constants (Ki) of DNA-dependent RNA polymerase B (or II) from calf thymus were measured for eight synthetically obtained bicyclic amanitin-like thioethers, two R-sulfoxides, and two S-sulfoxides. These Ki values were compared with those of

Toxic and Psychoactive Fungi in Forensic Toxicology: Analytical Challenges and Postmortem Interpretation

open access: yesApplied Sciences
Mushroom-related intoxications pose a distinctive challenge for forensic medicine because early manifestations are non-specific, latency may be prolonged, and co-exposures can obscure the mechanism of death. This narrative review summarizes key toxic and

Effects of interrupting the enterohepatic circulation in amatoxin intoxications

open access: yesClinical Toxicology
Interruption of the enterohepatic circulation is regarded as an effective way to treat patients with amatoxin poisoning. Nonetheless, its effectiveness has not yet been systematically evaluated. Therefore, we performed a systematic review to investigate the role of enterohepatic circulation on patient outcome and clinical laboratory values.

Haemoperfusion in Amanita phalloides poisoning

open access: yes, 1995
Amanita phalloides is responsible for about 90 per cent of all fatal cases of mushroom intoxication, The amatoxins, the main toxic component of these fungi, are responsible for gastro-intestinal symptoms, as well as hepatic and renal ...

Amatoxins Against Cancer

open access: yes
Over the past two years, I have devoted sustained research effort to the therapeutic potential of amatoxins as payloads in targeted cancer therapies. As the author of this work, amanitologist, Danny LeVan-Cicchetti, I have followed closely the notable advances that have taken place in this field between 2024 and 2026.
