Özet

In this study, 12 new compounds were synthesized, six of which were 3(2H)-pyridazinone (9a-f) and the others were 1(2H)-phthalazinone (10a-f) derivatives. The chemical structures of new compounds were confirmed by H-1-NMR, C-13-NMR, mass, and elemental analysis. The antioxidant properties of all the synthesized compounds were evaluated by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and nitric oxide radical scavenging assays. Moreover, cholinesterase inhibitory profiles of the synthesized compounds were determined using an in vitro assay based on a modified version of the Ellman protocol. Almost all the synthesized compounds displayed promising antioxidant activity, particularly in the DPPH radical scavenging assay, however, their inhibitory activities on cholinesterase enzymes pointed out structure specific interactions .
