Novel Schiff base scaffolds derived from 4-aminoantipyrine and 2-hydroxy-3-methoxy-5-(phenyldiazenyl)benzaldehyde: Synthesis, antibacterial, antioxidant and anti-inflammatory.

The synthesis of four new azo-Schiff base ligands from 2-hydroxy-3-methoxy-5-(phenyldiazenyl)benzaldehyde and 4-aminoantipyrine is described in this study. The molecular structures of all the scaffolds were confirmed using NMR spectroscopies such as H and C, as well as FT-IR and Mass spectroscopy. After successful synthesis and characterization of all the ligands, their in vitro antibacterial, antioxidant and anti-inflammatory activities were carried out by using standard protocols.
