Photochemical and antibacterial properties of ruthenium complex of N,N’-bis(benzimidazole-2yl-ethyl)ethylenediamine under visible light: Experimental and theoretical studies

Synthesis, characterization, photophysical, and magnetic studies of mixed‐ligand thorium(IV) complex of 2‐hydroxy‐5‐sulfobenzoic acid and 1,10‐phenanthroline

“…The bond lengths are in agreement with the values obtained under experimental conditions for the similar systems. [ 75–78 ] In case of IR (Figure S1), the main peaks were found to be in good coherence with the peaks obtained for the IR evaluated experimentally. Moreover, the UV spectrum (Figure S2) shows the two main bands in the range of 250 to 350 nm, which matches well with the UV spectrum obtained experimentally.…”

Synthesis, Structural Elucidation, In Vitro Antibacterial Activity and Antioxidant Property of a Novel Oxo‐Vanadium(V) Dimer Complex Incorporating Deferasirox Ligand

“…The result could be described according to the chelation theory, which proposed that chelation could improve the capability of a complex to pass via a cell membrane [20,24] . In addition, the biological activity of materials is associated with antagonistic or synergistic effects of components [25] . Moreover, this complex was compared with some V(V) complexes containing nitrogen and oxygen donor ligands previously synthesized [24,26] in terms of antimicrobial activity against S. aureus, B. cereus, E. coli, and P. aeruginosa .…”

Ruthenium‐based Photoactive Metalloantibiotics†

“…Wawrzycka and coworkers have shown that the complexes, mer ‐[Ru III (2‐bimc) 3 ]·H 2 O and cis ‐[Ru IV Cl 2 (2,3‐pydcH) 2 ]·4H 2 O, display bacteriostatic activity and inhibit the growth of both Gram (+) and Gram (−) bacteria ( 2‐bimc = 1 H ‐benzimidazole‐2‐carboxylic acid and 2,3‐pydcH = pyridine‐2,3‐dicarboxylic acid) (28). The bactericidal activity of the complex, [Ru II L1ClP(Ph 3 )]Cl, (L1 = N,N′‐bis(benzimidazol‐2‐yl‐ethyl)ethylenediamine) was reported to be due to abnormal cell morphology, as a result of the leakage of lactate dehydrogenase upon entry of the metal complex into cells (29). Antibacterial peptides have been coupled to ruthenium complexes to target bacterial infection and specifically accumulate in bacteria (30).…”
