Özet

In this study thirteen 6-substituted-3(2H)-pyridazinone-2-acety1-2-(substituted/-nonsubstituted benzal)hydrazone V derivatives were synthesized acetylcholinesterase and butyrylcholinesterase inhibitors. Ten of the synthesized compounds were synthesized for the first time in this study and the rest of them had been synthesized in a previous study. The structures of compounds V were elucidated by IR, H-1-NMR and MASS spectra. The acetylcholinesterase (AChE) and butyrylcholinesterase (BChe) inhibitory activities of V derivatives were measured using Ellman's method. While some of the 6-substituted-3(2H)-pyridazinone-2-propyl-3-(substituted/-nonsubstituted benzal)hydrazone V derivatives exhibited significant AChE inhibitory activity, none of the compounds showed BChE inhibitory activity. These results indicate that V derivatives were AChE inhibitors with AChE/BChE selectivity.
