Anatoxin-a, also known as Very Fast Death Factor (VFDF), is a secondary, bicyclic amine alkaloid and cyanotoxin with acute neurotoxicity. It was first discovered in the early 1960s in Canada, and was isolated in 1972. The toxin is produced by multiple genera of cyanobacteria and has been reported in North America, South America, Central America, Europe, Africa, Asia, and Oceania. Symptoms of anatoxin-a toxicity include loss of coordination, muscular fasciculations, convulsions and death by respiratory paralysis. Its mode of action is through the nicotinic acetylcholine receptor (nAchR) where it mimics the binding of the receptor's natural ligand, acetylcholine. As such, anatoxin-a has been used for medicinal purposes to investigate diseases characterized by low acetylcholine levels. Due to

dbo:abstract
  • Anatoxin-a je tuhá látka, sekundární amin a bicyklický alkaloid, cyanotoxin významný především svým výskytem v přírodě a akutní toxicitou. Poprvé byl izolován v roce 1972. Tento toxin je produkován 7 různými rody sinic a symptomy otravy zahrnují ztrátu koordinace, křeče a dýchací paralýzu, která může být smrtelná. Anatoxin-a působí na nAchR receptory, kde napodobuje acetylcholin (jedná se o nervový jed). Anatoxin-a by se neměl zaměňovat s , který má podobné účinky – ale je strukturně nepříbuzný. Anatoxin-a a jeho deriváty byly a jsou zkoumány jako možné léčivé látky pro léčbu chorob, jako je Parkinsonova choroba. (cs)
  • Anatoxin A, auch bekannt als Very Fast Death Factor (VFDF), ist ein neurotoxisches Alkaloid, das von einer Vielzahl von Cyanobakterien produziert wird. Das Toxin als Reinsubstanz, bei Raumtemperatur eine ölige Flüssigkeit, wurde 1977 von John P. Devlin aus einer Kolonie der Cyanobacterien Anabaena flos-aquae, NRC-44h, extrahiert. Anatoxin A ist außerordentlich toxisch. Der LD50-Wert für Mäuse liegt bei intraperitonealer Verabreichung bei etwa 0,25 mg/kg KG. Bei oraler Aufnahme tötet es innerhalb von wenigen Minuten. In sehr kleinen Mengen wird Anatoxin A für die Grundlagenforschung produziert. (de)

Its mode of action is through the nicotinic acetylcholine receptor (nAchR) where it mimics the binding of the receptor's natural ligand, acetylcholine. As such, anatoxin-a has been used for medicinal purposes to investigate diseases characterized by low acetylcholine levels. Due to its high toxicity and potential presence in drinking water, anatoxin-a poses a threat to animals, including humans. While methods for detection and water treatment exist, scientists have called for more research to improve reliability and efficacy. Anatoxin-a is not to be confused with guanitoxin (formerly anatoxin-a(S)), another potent cyanotoxin that has a similar mechanism of action to that of anatoxin-a and is produced by many of the same cyanobacteria genera, but is structurally unrelated.

  • Anatoxina-a, também conhecida como "Fator de Morte Muito Rápido" (em inglês: Very Fast Death Factor (VFDF), é uma cianotoxina e amina secundária bicíclica, alcaloide, com neurotoxidade aguda. A toxina é produzida por pelo menos 5 gêneros diferentes de cianobactérias, incluindo , , , e e teve presença relatada na América do Norte, Europa, África, Ásia e Nova Zelândia. A toxina é muito menos provável de ser identificada no hemisfério sul. Os sintomas de exposição à anatoxina são perda de coordenação motora, fasciculação muscular, convulsões e morte por paralisia respiratória. Seu modo de ação é pelo receptor nicotínico, onde age como análoga da acetilcolina. A molécula não é degradada pela colinesterase, por isso causa estimulação permanente das células musculares levando à paralisia. É uma das mais poderosas moléculas agonistas do receptor nicotínico de acetilcolina. (pt)
