ABSTRACT
Bridged-tricyclic cyanoguanidines 1 were found to be active as insecticides. The preparation and structure-activity relationships of oxacyclic (X=O) and carbocyclic (X=CH(2)) analogues of 1 is described. Compounds 1 were found to inhibit acetylcholinesterase with IC(50) values comparable to the organophosphate Paraoxon. Unlike organophosphates, cyanoguanidines 1 were shown to reversibly bind acetylcholinesterase. This mode of action is shared by the structurally-related natural product Huperzine A.
