Seven ketoanalogs of acetylcholine were synthesized and evaluated as inhibitors of humanplacentalcholineplacentalcholineacetyltransferase. Their potencies for inhibition of horse serum cholinesterase and stimulation of cholinergic receptors in the longitudinal ileal muscle of the guinea pig were investigated. The most potent and selective inhibitor of cholineacetyltransferase was (2-benzoyl
