KBR 2822 

KBR 2822 is an esterase inhibitor used to inhibit neuropathic target esterase (NTE), the target of delayed organophosphate-induced neuropathy. Experiments have shown that chronic oral administration of KBR-2822 (0.2 or 0.4 mg/kg/day) to chickens does not induce neuropathy and does not exacerbate toxic or traumatic axonopathy, even in the absence of intentional axonal injury. In the control group, administration of non-neuropathic Paraoxon (0.05 mg/kg/day orally) showed a mean AChE inhibition of 45% and no NTE inhibition. After chronic administration of KBR-2822, PMSF (120 mg/kg subcutaneously, 24 hours after the last KBR-2822 dose) was given, and KBR-2822-treated chickens did not develop neuropathy, while chickens treated with neuropathic DFP did. This suggests that sustained facilitatory "stress" is harmless to chicken axons in the absence of concurrent biochemical or neurotoxic insults.
