  1. Palytoxin is a polyol marine coelenterate toxin composed of substituted N-3-hydroxypropyl-trans-3-amidoacrylamides and produced by species of Palythoa and Zoanthus soft corals (collectively called zoantharians), either as a defence mechanism or to assist them in capturing prey. An ionophore that forms cation channels through Na+/K+-ATPase, it.
  2. Palytoxin (PTX) is a very dangerous toxin produced by several marine species. PTX originally was isolated in 1971 in Hawaii from the seaweed-like coral 'Limu make o hana' (Seaweed of Death from Hana). Zoanthids (Anthozoa, Hexacorallia) are colonial anemones that contain this toxin
  3. Palytoxin is a high-molecular mass fatty polyalcohol produced by zoanthid corals of the genus Palythoa.It is one of the most toxic nonprotein compounds known and contains one of the longest carbon chain of all naturally occurring molecules

Palytoxin je smrtelně jedovatá látka, má a určitě ještě bude mít na svědomí řadu lidských životů. Pokud by se ale našel způsob jak docílit toho, aby působil pouze na nemocné buňky a zdravé nechal na pokoji, mohl by se z něj stát užitečný nástroj pro boj se zhoubnými chorobami Palytoxin acts extracellularly; it binds to surface cell receptors and creates a 'pore' in the cell membrane. Specifically, it binds to Na +, K +-ATPase, or the sodium pump enzyme in charge of osmoregulation (Bignami 1992). This is the same binding site as ouabain, the plant derived toxin used as arrow poison in eastern Africa Palytoxin, a nonphorbol ester-type tumor promoter, stimulated the production of prostaglandin E2 (PGE2) and bone resorption in neonatal mouse calvariae in organ culture. The action of palytoxin on bone resorption occurred at extraordinarily low concentrations; enhanced resorption was regularly obser - Palytoxin is a very powerful toxin that can be contained in some Palythoa (Palys) and Zoanthid (Zoa) species. This toxin is used by the coral as a natural defense mechanism. Not all contain it and not everyone is susceptible to the toxin, but it can be very dangerous to your health if you are exposed to it and it could lead to life. Palytoxin Quick Facts. Palytoxin is one of the most toxic poisons in the world. Capable of damaging every cell in your body. Can cause tissue damage, a decrease in respiratory function, coma or death. Discovered in Hawaii, the name limu-make-o-Hana, literally means seaweed of death from Hana. According to the CDC there is no antidote

  1. La découverte de la palytoxine a pour origine une légende hawaïenne de l'île de Maui.Près du port de Hana, un village côtier subissait une malédiction, lorsque des bateaux partaient pour la pèche, il manquait un pécheur à leur retour.Les villageois, furieux, s'en prirent à un vieil ermite que l'on supposait responsable de la malédiction
