Antimicrobial Potential of a Formazanate‐Based Mercury(II) Complex: In Vitro ‐ and In Silico ‐Based Insights
Year: 2024
Type: article
Abstract: Herein, we present a distorted square pyramidal mercury complex, [Hg II (L)Cl] ( 1 ), based on a quinoline‐substituted formazan ligand LH[3‐Cyano‐1,5‐(quinolin‐8‐yl)formazan], which was evaluated for its anti‐bacterial activity in vitro . Complex 1 was prepared by refluxing 3‐Cyano‐1,5‐(quinolin‐8‐yl)formazan ligand and mercury chloride(II) in equimolar quantity and was characterized utilizing a range of analytical methods, including single crystal X‐ray diffraction (SCXRD) technique. The crystal packing in complex 1 has been elucidated using supramolecular investigations, which have shown the presence of fascinating Hg−Cl⋅⋅⋅Hg intermolecular spodium bonds of the order 3.348 Å. The antimicrobial activity of the formazanate‐based mercury(II) complex ( 1 ) was assessed against Gram‐positive ( Staphylococcus aureus and Bacillus subtilis ) and Gram‐negative ( Escherichia coli and Pseudomonas aeruginosa) bacterial pathogens. In addition, the plausible therapeutic target of the formazanate‐based mercury(II) complex was determined through in silico pharmacophore‐guided rational drug designing approach. Based on the in silico results, a conceivable molecular mechanism of the observed bactericidal action of the newly synthesized [Hg II (L)Cl] complex ( 1 ) has also been suggested.
