Acetylcholinesterase (AChE) regeneration after DFP?

Dear netters, 

Acetylcholinesterase (AChE) can be inhibited with 
diisopropylfluorophosphate (DFP). Howver, the inhibited enzyme can be 
reactivated with oximes or hydroxamic acid derivatives. In our lab we 
would like to reactivate a different (parasitic) esterase, which has been 
inhibited with DFP. However, most of the reactivators described in the 
literature do not seem to be available from the usual suppliers. 

Can anybody point us to any of the following compounds (commercial 
availability, a kind gift or an easy synthetic approach):

- P2S (1-methyl-2-hydroxyiminomethylpyridinium methane sulfonate)
- hydroxyiminoacetone
- N-phenylnicotinohydroxamic acid
- formhydroxamic acid

Please send an email to Dundee and/or answer to this newsgroup.
