diverse lipophilic and electronic properties for these bisbenzyl bispyridinium derivatives (so‐called DUO series), the lateral ring substitution was systematically varied. The lowest IC50 value against AChE found thus far in the DUO series was 0.34 μM. Dockingstudies were carried out to elucidate the differences in biologicalactivity. A general binding mode for nearly all compounds could be identified
