Beschreibung

a-Amanitin is a cyclic peptide that is found in mushrooms of the genus "Amanita", which can cause toxic effects if eaten. It has been shown to inhibit the growth of cancer cells by inhibiting mitochondrial membrane potential and reducing dna synthesis, as well as by triggering apoptosis. The structural analysis of a-amanitin has shown that it binds to surface glycoproteins on myeloma cells and triggers the activation of toll-like receptors (TLRs), which initiate an immune response against myeloma cells. This cyclic peptide also has been shown to reduce hepatic steatosis in mice by affecting mitochondrial membrane potential and inducing metabolic changes.
Indocyanine green, a fluorescent dye, has been shown to prevent α-amanitin toxicity in mice (Wang et al, 2023), and could be a possible antidote to poisoning by Amanita, such as death cap mushroom Amanita phalloides, which is the cause of over 90% of fatal mushroom poisoning.
