Abstract

Screening of a compound library against endothelin receptors (ETA and ETB) revealed PD 102566 (compound 1) as an ETA selective antagonist. Synthesis and structure-activity relationships (SAR) of a series of analogs are described.

Abstract

A new type of dihydroquinazoline-based inhibitor of acetylcholinesterase (AChE) is described. These compounds were designed to interact with the catalytic site of AChE in a manner similar to the known inhibitor tacrine. In a manner analogous to the potency enhancement obtained by addition of chlorine atoms to the tacrine molecule, a 3-chloro derivative of the parent hexahydroazepino[2,1-b]quinazoline structure was found to be about 8 times more potent as an AChE inhibitor than the unsubstituted compound.
