Abstract : Structure activity relationship studies of hemicholinium (HC-3) analogs directed toward better understanding both the spatial aspect of the receptor and interatomic distances between the 2 cationic heads. Several series of compounds including 4,4' biphenyl and trans/trans-cyclohexyl derivatives are being investigated and both series are potent inhibitors of acetylcholine synthesis. One compound, N-methyl 4-methyl piperidine derivative in the biphenyl series, is a very active inhibitor of ACh synthesis. The tertiary amine analog is an active inhibitor of synthesis of acetylcholine. It is much less active than the quaternary derivative. Keywords: Cholinesterase inhibitors; Transport properties.
