Synthesis, Spectroscopic, Structural and Molecular Docking Studies of Some New Nano-Sized Ferrocene-Based Imine Chelates as Antimicrobial and Anticancer Agents

Abstract

The newly synthesized organometallic acetyl ferrocene imine ligand (HL) was obtained by the direct combination of 2-acetyl ferrocene with 2-aminothiophenol. The electronic and molecular structure of acetyl ferrocene imine ligand (HL) was refined theoretically and the chemical quantum factors were computed. Complexes of the acetyl ferrocene imine ligand with metal(II)/(III) ions (Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II)) were fabricated. They were inspected by thermal (DTG /TG), spectroscopic techniques (FT-IR, 1H NMR, mass, UV–Vis), molar conductivity, and CHNClM to explicate their structures. Studies using scanning electron microscope (SEM) were conducted on the free acetyl ferrocene imine ligand and its Cd(II) chelate to confirm their nano-structure. To collect an idea about the effect of metal ions on anti-pathogenic properties upon chelation, the newly synthesized acetyl ferrocene imine ligand and some of its metal chelates were tested against a variety of microorganisms, including Bacillus subtilis, Staphylococcus aureus, Salmonella typhimurium, Escherichia coli, Aspergillus fumigatus, and Candida albicans. The ligand and its metal chelate were tested for cytotoxic activity in human cancer (MCF-7 cell viability) and human melanocyte cell line HBF4. It was discovered that the Cd(II) chelate had the lowest IC50 of the three and thus had the prior activity. Molecular docking was utilized to investigate the interaction of acetyl ferrocene imine ligand (HL) with the receptors of the vascular endothelial growth factor receptor VEGFR (PDB ID: 1Y6a), human Topo IIA-bound G-segment DNA crystal structure (PDB ID: 2RGR), and Escherichia coli crystal structure (PDB ID: 3T88).

Synthesis, structural characterization, and in vitro biological activity studies of ternary metal complexes of 1,10‐phenanthroline and the anti‐inflammatory bromhexine drug

“…This observation was inversed with Gram-negative bacteria as BHX mixed ligand complexes were highly active than ofloxacin-based metal complexes. 14 ((Z)-cyclopenta-1,3-dien-1-yl(2-(1-((3-hydroxyphenyl) imino)ethyl)cyclopenta-2,4-dien-1-yl)iron) and its metal chelates were prepared by Mai et al 37 and tested against different strains of Gram-positive and Gram-negative bacteria. Generally, it was observed that the BHX mixed ligand complexes are highly more reactive as antibacterial agents than ferrocene-based Schiff base metal complexes.…”

Development of Metal Complexes for Treatment of Coronaviruses

“…With continued interest in organic synthesis, it was desirable to identify efficient and effective synthesis methods due to their wide range of pharmacological actions. Antibiotics [ 26 ], anti-inflammatory medications [ 27 ], muscle relaxants [ 28 ], ant tubercular drugs [ 29 ], and antiviral agents [ 30 ] are only a few of the drugs that contain this backbone. Unfortunately, the virus’s rapid spread resulted in a significant rate of mortality and morbidity over the globe [ 31 ].…”

Innovation of Imine Metal Chelates as Corrosion Inhibitors at Different Media: A Collective Study

“…Schiff bases are promising chelating ligands in coordination chemistry due to their propensity to develop stable chelates with transition metals [ 1 , 2 , 3 , 4 , 5 , 6 ]. Schiff base metal chelates were widely investigated due to their amazing chemical and physical properties.…”
