In recent years potent anticholinesterase (antiChE) drugs, the alkyl phosphates, were introduced for the treatment of myasthenia gravis. These include di-isopropyl fluorophosphate (DFP),2 tetraethylpyrophosphate (TEPP),3 and hexaethyltetraphosphate (HETP).4 DFP was found to be a very effective antiChE agent, but toxic and not effective therapeutically. HETP and TEPP were found to be
