Potential bioactive Schiff base compounds: Synthesis, characterization, X-ray structures, biological screenings and interaction with Salmon sperm DNA

Three Schiff base compounds ofN'-substituted benzohydrazide and sulfonohydrazide derivatives: N'-(2-hydroxy-3-methoxybenzylidene)-4-tert-butyl- benzohydrazide (1), N'-(5-bromo-2-hydroxybenzylidene)-4-tert-butylbenzohydrazide (2) and N'-(2-hydroxy-3-methoxybenzylidene)-4-methylbenzenesulfonohydrazide (3) were synthesized and characterized by elemental analysis, FT-IR, (1)H, (13)C NMR spectroscopy and single crystal analysis. The title compounds...
