Neurotoxins are toxins that are destructive to nerve tissue (causing neurotoxicity). [3] Neurotoxins are an extensive class of exogenous chemical neurological insults [ 4 ] that can adversely affect function in both developing and mature nervous tissue. [ 5 ]
The prognosis depends upon the length and degree of exposure and the severity of neurological injury. In some instances, exposure to neurotoxins or neurotoxicants can be fatal. In others, patients may survive but not fully recover. In other situations, many individuals recover completely after treatment. [15]

Brevetoxin (PbTx), or brevetoxins, are a suite of cyclic polyether compounds produced naturally by a species of dinoflagellate known as Karenia brevis.Brevetoxins are neurotoxins that bind to voltage-gated sodium channels in nerve cells, leading to disruption of normal neurological processes and causing the illness clinically described as neurotoxic shellfish poisoning (NSP). [1]
Alpha-neurotoxins are a large group; over 100 postsynaptic neurotoxins having been identified and sequenced. [12] α-neurotoxins attack the Nicotinic acetylcholine receptors of cholinergic neurons. They mimic the shape of the acetylcholine molecule, and so fit into the receptors, where they block the ACh flow, leading to a feeling of numbness ...
The three-dimensional structure of alpha-bungarotoxin, an alpha-neurotoxin from the venom of Bungarus multicinctus. Gold links indicate disulfide bonds. From 1] α-Neurotoxins are a group of neurotoxic peptides found in the venom of snakes in the families Elapidae and Hydrophiidae. They can cause paralysis, respiratory failure, and death.
Neosaxitoxin (NSTX) is included, as other saxitoxin-analogs, in a broad group of natural neurotoxic alkaloids, commonly known as the paralytic shellfish toxins (PSTs).The parent compound of PSTs, saxitoxin (STX), is a tricyclic perhydropurine alkaloid, which can be substituted at various positions, leading to more than 30 naturally occurring STX analogues.
