A series of novel 1-[(1R)-1-(6-fluoro-1,3-benzothiazol-2-yl)ethyl]-3- substituted phenyl ureas were synthesized by the condensation of (1R)-1-(6-fluoro-1,3-benzothiazol-2-yl)ethanamine with substituted phenyl isocyanates under mild conditions. Their structures were confirmed 1H, 13C, and 19F NMR spectra, and elemental analyses. The optical activities were confirmed by optical rotation measurements. The inhibition activity of 1-[(1R)-1-(6-fluoro-1,3-benzothiazol-2- yl)ethyl]-3-substituted phenyl ureas to acetylcholinesterase (ACHE) and butyrylcholinesterase (BCHE) was also tested. Preliminary bioassay indicated that the target ureas displayed excellent acetylcholinesterase and butyrylcholinesterase inhibition activity.
