[PMID: 36335746 DOI: 10.1016/j.jinorgbio.2022.112055] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 10/20/2022] [Accepted: 10/25/2022] [Indexed: 11/06/2022]
Abstract
Iron is the trace element of natural selection by the biological systems due to its versatile coordination chemistry, and is recently explored for medicinal and diagnostic applications. Photo-activated states of iron complexes exhibiting substitution, dissociation, isomerization reactions, intramolecular redox reactions or energy transfer to other molecules have attracted the attention across the globe for the potent applications in photo-chemotherapy. There is a significant advancement on the development of iron-based complexes for photochemotherapeutic applications. Here in we reviewed the photo-activated states and photochemistry of iron complexes, and recent advances made in the area of photochemotherapy of iron complexes relevant to the photochemistry of iron complexes.

Abstract
Antimicrobial photodynamic therapy (aPDT) has emerged as a novel and promising approach for the treatment of pathogenic microorganism infections. The efficacy of aPDT depends greatly on the behavior of the photosensitizer. Herein, we report the design, preparation, antimicrobial photodynamic activities, as well as structure-activity relationships of a series of photosensitizers modified at the meso position of a 1,3,5,7-tetramethyl BODIPY scaffold with various pyridinyl and pyridinium moieties. The photodynamic antimicrobial activities of all photosensitizers have been tested against Staphylococcus aureus, Escherichia coli, Candida albicans, and Methicillin-resistant S. aureus (MRSA). The methyl meso-(meta-pyridinium) BODIPY photosensitizer (3c) possessed the highest phototoxicity against these pathogens at minimal inhibitory concentrations (MIC) ranging from 0.63 to 1.25 μM with a light dose of 81 J/cm2. Furthermore, 3c exhibited an impressive antimicrobial efficacy in S. aureus-infected mice wounds. Taken together, these findings suggest that 3c is a promising candidate as the antimicrobial photosensitizer for combating pathogenic microorganism infections.
