Abstract––In this research, a series of hydrazine-hydrazone derivatives (Ia-g), (IIa-h) were synthesized to discover new antioxidant and anticholinesterase agents. The structures of synthesized compounds were characterized by spectroscopic data using UV, IR, ¹H, ¹³C NMR, mass spectroscopy, and elemental analysis. The bio-evaluation of the synthesized compounds (Ia-g), (IIa-h) were evaluated according to in vitro activity assays. The results of β-carotene/linoleic acid assay showed that among the synthesized compounds, the (Ib), (Ie), (IIb-IIe), and (IIh) compound exhibited higher activity for the lipid peroxidation inhibitory activity. In the DPPH free scavenging activity and the cation radical scavenging activity in ABTS^•+ activity, compound (IIb) was found to be more active. In the CUPRAC reduced power assay, the A0.5 values of all synthesized compounds were better than α-TOC. In AChE assay, compound (IIb) exhibited the most activity with IC₅₀=11.12±0.74 μM, while the compounds (Ib-g) and (IIb-h), exhibited excellent activity than the positive standard galantamine (IC₅₀= 46.06±0.10 μM) in the BChE assay.

Keywords: sulfonamide, hydrazone, antioxidant activity, anticholinesterase inhibitory activity, Lipinski's rules
