[Neurotoxins with anticholinesterase activity and their possible use as warfare agents].

Anatoxin-a(s), onchidal and fasciculins are neurotoxins with anticholinesterase activity. An intoxication by these neurotoxins is characterized by cholinergic syndromes similar to organophosphate insecticide and nerve agent intoxications. Anticholinesterase neurotoxins, as well as other toxins, have some disadvantages if used as weapons of mass destruction. Drawbacks include difficulties to produce them in big quantities and their dissemination in form of aerosols. However, other properties such as high toxicity, improbable identification with common commercial portable detectors for chemical warfare agents and toxic industrial chemicals, as well as the lack of effectiveness of antidotal treatments with oximes may make them attractive in order to be used in military operations or terrorist attacks. For these reasons, it should be necessary to control these neurotoxins through international treaties which have real verification measures such as the Chemical Weapons Convention.
