SUMMARY
In this article, we have followed up the relationship between the ability to reactivate
acetylcholinesterase inhibited by organophosphorus compounds and the length of linking chain
between two 4-hydroxyiminomethylpyridinium rings of acetylcholinesterase reactivators. alpha,omega-bis(4-hydroxyiminomethylpyridinium) alkanes have
been used as the tested acetylcholinesterase
reactivators. These oximes differ in the number of methylene groups on the connecting chain. A
three or four membered linking chain seems to be the ideal length for the satisfactory reactivation
potency with the exception of reactivators of cyclosarin-inhibited acetylcholinesterase. In this case,
the most efficacious acetylcholinesterase reactivator has one methylene group on the connecting
chain.
