Research output: Contribution to journalArticlepeer-review


A rational approach is presented toward the establishment of a structure-activity relationship in a series of reactivators of DFP-inhibited AChE. The value of kt, the first-order reactivation rate constant, at pH 7.4 is a function of both the nucleophilicity of the reactivator molecule and its basicity, reaching an optimum for compounds with a pKa value in the range 7.6-8.0.
