cyclosarin antidote
This is significant because the same results were obtained for two different species.Results obtained using in vivo results are not always similar with in vitro results (Previous studies with cyclosarin-poisoned animals suggested a poor efficacy of the marketed oximes obidoxime and pralidoxime, whereas the newer oximes HI-6 and HLo 7 proved to be effective antidotes (Oxime BI-6 was also found to be potent reactivator of cyclosarin-inhibited AChE. However, validation of such an approach, using components of gross EEG recordings, may not be plausible because of the large number of ionotropic channels represented. Nerve agent poisoning is conventionally treated using a combination of a cholinolytic (atropine mostly) to counteract the accumulation of acetylcholine and acetylcholinesterase reactivators (pralidoxime or obidoxime) to reactivate inhibited acetylcholinesterase.

50), as well as the enzyme inhibited by cyclosarin (51). Cyclosarin (GF) also demonstrates considerably greater toxicity than sarin (GB) in humans. Both rats and guinea pigs are well-protected against soman-induced seizures and neuropathology when pretreated with huperzine, whereas pyridostigmine does not have such effects (When pyridostigmine is combined with benactyzine and trihexyphenidyl (exerting both cholinergic and glutamatergic antagonism) in rats, effective protection is obtained against signs of neurotoxicity induced by soman.

Cyclosarin was also discovered during WWII but the details were lost and it was rediscovered in 1949. The cholinergic system is the only known system to terminate the action of a neurotransmitter via enzymatic cleavage.
