corresponding in vitro evaluation for reactivation of paraoxon-inhibited electric eelacetylcholinesterase (EeAChE) and recombinant human acetylcholinesterase (rHuAChE) are reported. Several newly synthesized compounds efficiently reactivatedinhibited EeAChE, but were poor reactivators of inhibited rHuAChE. Compounds bearing a thiophene ring in the side chain (20, 23, 26 and 29) showed better reactivation (24–37%

quaternary pyridinium oximes against a number of lower pathogenicity BSL‐1 and 2 agents. In general, our compound panel had little to no antimicrobial action except for thiophene‐ and benzothiophene‐substituted monoquaternary pyridinium compounds 21 and 24 that showed moderate antibacterial activity against Staphylococus aureus and methicillin‐resistant S. aureus with IC50 values ranging from 12.2
