Discovery of metal-based complexes as promising antimicrobial agents

Eur J Med Chem. 2021 Nov 15:224:113696. doi: 10.1016/j.ejmech.2021.113696. Epub 2021 Jul 8.

Abstract

The antimicrobial resistance (AMR) is an intractable problem for the world. Metal ions are essential for the cell process and biological function in microorganisms. Many metal-based complexes with the potential for releasing ions are more likely to be absorbed for their higher lipid solubility. Hence, this review highlights the clinical potential of organometallic compounds for the treatment of infections caused by bacteria or fungi in recent five years. The common scaffolds, including antimicrobial peptides, N-heterocyclic carbenes, Schiff bases, photosensitive-grand-cycle skeleton structures, aliphatic amines-based ligands, and special metal-based complexes are summarized here. We also discuss their therapeutic targets and the risks that should be paid attention to in the future studies, aiming to provide information for researchers on metal-based complexes as antimicrobial agents and inspire the design and synthesis of new antimicrobial drugs.

Keywords: Antimicrobial agents; Antimicrobial resistance; Metal-based complexes; Organometallic compounds.
