Abstract
Synthesis of salen type Schiff base ligand by the condensation of butane 1,4-diamine with 5-bromosalicyaldehyde has been done. Further, three new mononuclear Schiff based complexes of Cu(II), Zn(II) and Pd(II) have been prepared by the reaction of the Schiff base ligand with appropriate metal salts. The developed Schiff base ligand and metal complexes of Cu(II), Zn(II) and Pd(II) have been well characterized by various spectroscopic techniques like UV–Vis, FT-IR, 1H-NMR, 13C-NMR, EPR, Mass and powder XRD. All the synthesized Schiff base compounds have been tested for antibacterial, antifungal, hemolysis assay and DNA binding activities. The zone inhibition measurements revealed the supremacy and enhanced efficiency of metal complexes as compared to free ligand. The molecular modelling studies were carried to analyze the bonding affinity and inhibition probability of the synthesized complexes with the S. aureus nucleoside diphosphate kinase receptor. The in-silico pharmacokinetics studies such as Lipinski's rule, Veber's rule, drug-likeness score and physiochemical parameters analysis predicted the drug-likeness of the synthesized compounds.
