Several esters of phosphoric acid are potent inhibitors of the cholinesterase (ChE) enzymes which are present in practically all animal tissues, and, as a result, have important pharmacologic properties. Lange and von Krueger1 were the first to note the high toxicity of one group of these compounds, the alkyl fluorophosphates, which includes di-isopropyl fluorophosphate (DFP) (figure 1). The effects of DFP were found to be due to its ability to inhibit ChE enzymes irreversibly,2, 3 a property which enabled its utilization in the study of the rôle that ChE enzymes play in normal function and in disease.4 DFP has
