Simultaneous binding to the catalytic and peripheral sites of acetylcholinesterase (AChE) is invoked to explain why the new drug (S,S)-(-)- 3, in which two aminoquinolinone units are linked by a dodecamethylene tether, is more than twice as potent as the natural product huperzine A (-)-1 in the inhibition of ACHE. In contrast aminoquinolinone (±)-2, which retains much of the functionality of (-)-1, inhibits AChE only very weakly.
