Synthesis of tricyclic analogs of stephaoxocanidine and their evaluation as acetylcholinesterase inhibitors

Bioorg Med Chem Lett. 2005 Jun 2;15(11):2711-5. doi: 10.1016/j.bmcl.2005.04.005.

Abstract

The synthesis of simplified analogs of the novel isoquinoline alkaloid stephaoxocanidine, carrying the oxazaphenalene ABC-ring system of the natural product, and their activity as inhibitors of the enzyme acetylcholinesterase, are reported. 5,6-Dimethoxy-7H -8-oxa-1-aza-phenalen-9-one (5) was as active as a Narcissus extract enriched in galantamine.
