A series of 5-amino-5,6,7,8-tetrahydroquinolinones was designed and synthesized as acetylcholinesterase inhibitors. The compounds are related to hyperzine A, a naturally occurring cholinesterase inhibitor. They inhibit acetylcholinesterase in vitro, and many are active in vivo in reversing a scopolamine-induced impairment of 24 h memory in a passive avoidance paradigm. Although these compounds were designed as partial structures of huperzine A, it is unlikely that they bind to the enzyme in a similar fashion, since they lack the unsaturated three-carbon bridge of huperzine A and both the quinolinone nitrogen and the amino group must be substituted in order to obtain good enzyme affinity.
