What are Schiff base ligands?

Abstract. Schiff bases are versatile organic compounds which are widely used and synthesized by condensation reaction of different amino compound with aldehydes or ketones known as imine. Schiff base ligands are considered as privileged ligands as they are simply synthesized by condensation.

What is the use of Schiff base?

Schiff bases are some of the most widely used organic compounds. They are used as pigments and dyes, catalysts, intermediates in organic synthesis, and as polymer stabilisers [2].

What is a Schiff base formation?

Schiff bases are typically formed by the condensation of a primary amine and an aldehyde which involves the use of organic solvents such as methanol, tetrahydrofuran (THF), and 1,2-dichloroethane (DCE) [4.

What is the difference between Schiff base and Schiff reagent?

The terms Schiff base and Schiff’s reagent are used in analytical chemistry. The key difference between Schiff base and Schiff’s reagent is that the term Schiff base refers to either secondary ketimines or secondary aldimines, whereas the term Schiff’s reagent refers to a reagent used to test for aldehydes and ketones.

What is the Schiff base ligand (HL)?

The new ligand was characterized by elemental analysis and spectral techniques. The coordination behavior of a series of transition metal ions named Cr (III), Mn (II), Fe (III), Co (II), Ni (II), Cu (II), Zn (II) and Cd (II) with the newly prepared Schiff base ligand (HL) is reported.

What are the chemical properties of Schiff base compounds?

These compounds were characterized by elemental analysis, IR, mass, (1)H NMR, electronic spectra, magnetic moment, molar conductance, thermal analysis, p … The Co(II), Ni(II), Cu(II) and Zn(II) complexes of the Schiff base derived from imidazole-2-carboxaldehyde and 4-aminoantipyrine were synthesized.

How do Schiff base ligands interact with Escherichia coli and Staphylococcus aureus?

Molecular docking was used to predict the efficiency of binding between Schiff base ligand (HL) and both receptors of Escherichia coli (3 T88) and Staphylococcus aureus (3Q8U). The receptor of Escherichia coli (3 T88) showed best interaction with Schiff base ligand (HL) compared to receptor of Staphylococcus aureu (3Q8U).

What is the antimicrobial activity of synthesized ligand?

The synthesized ligand and its complexes were screened for antimicrobial activities against bacterial species ( Staphylococcus aureus and Bacillis subtilis, (gram positive bacteria)), ( Salmonella SP., Escherichia coli and Pseudomonas aeruginosa, (gram negative bacteria)) and fungi ( Aspergillus fumigatus and Candida albicans ).
