We synthesized carbamate-modified (-)-N-1-phenethylnorphysostigmine derivatives 3a-u and evaluated their anti-cholinesterase activities. In vitro evaluation showed that cyclohexylmethylcarbamate derivative 3u potently and selectively inhibits butyrylcholinesterase. (C) 2010 Elsevier Ltd. All rights reserved.

of (−)-phenserine (12), (−)-tolserine (14), (−)-cymserine (16) and (−)-phenethylcymserine (18) were synthesized to produce long-acting peripheral inhibitors of acetylcholinesterase or butyrylcholinesterase. Evaluation of their cholinesterase inhibition against human enzyme ex vivo demonstrated that, whereas compounds 5–8 possessed only marginal activity, 12, 14, 16 and 18proved to be potent anticholinesterases
