In this paper, fourteen novel AChE reactivators are described. Their design originated from a former promising compound K027.

These compounds were synthesized, evaluated in vitro on human AChE (hAChE) inhibited by tabun, paraoxon, methylparaoxon and DFP and then compared to commercial hAChE reactivators (pralidoxime, HI-6, trimedoxime, obidoxime, methoxime) or previously prepared compounds (K027, K203). Three of these novel compounds showed a promising ability to reactivate hAChE comparable or better than the used standards.

Consequently, a molecular docking study was performed for three of these promising novel compounds. The docking results confirmed the apparent influence of pi-pi or cation -pi interactions and hydrogen bonding for reactivator binding within the hAChE active site cleft.

The SAR features concerning the non-oxime part of the reactivator molecule are also discussed.
