Interaction of rhenium(I) complex carrying long alkyl chain with Calf Thymus DNA: Cytotoxic and cell imaging studies

A PRELIMINARY STUDY ON ELECTROCATALYTIC REDUCTION OF CO2 USING FAC-ReI(CO)3(4,4′-DI-METHYL-2,2′-BIPYRIDYL)((E)-2-((3-AMINO-PYRIDIN-4-YLIMINO)-METHYL)-4,6-DI-TERT-BUTYLPHENOL))+ COMPLEX

“…Theoretical evidence, using DFT level of theory that included spin-orbit effect confirm the former effect. [17][18][19][20] On the other hand, complexes of type neutral fac-Re(CO) 3 (X)Cl (with X=2,2′-bipyridyl or similar), have demonstrated activity for the selectively reduction of CO 2 to CO and the mechanistic pathways have been studied. [21][22][23][24][25] Based on these findings, our group have also been exploring a new kind of rhenium(I) tricarbonyl complexes of type fac-Re(CO) 3 (4,4'-di-methyl-2,2'bipyridyl)L + (C2, See Scheme 1), and its potential properties to the reduction of CO 2 .…”

Luminescent sensor for copper(II) ion based on imine functionalized monometallic rhenium(I) complexes

“…400-412 nm ( Table 2). With reference to previous literature available on the spectroscopic characteristics of rhenium(I)-tricarbonyl polypyridine complexes [54,55], we have assigned these high-energy intense band to ligand centered (LC) -* transition, which is also observed for the free ligands (Fig S14). The low energy absorption band at 400-412 nm has larger molar absorption coefficient (ε) than that is usually observed with metal to ligand charge transfer (MLCT) transition from the Re d-orbital to the * orbital of the ligand [d (Re) → * (ligand)] (Fig.…”

“…The observation of large ε value suggested that there could be additional contribution from ligand-centered transition. From previous reports, it can be assigned that the low energy absorption manifold can be due to a mix of MLCT and intraligand charge transfer (ILCT) transition of phenol-appended bipyridine ligand [54,55].…”

Photophysical and Biological Properties of Iridium Tetrazolato Complexes Functionalised with Fatty Acid Chains

“…Interestingly, only a few examples of metal complexes appended with fatty acid or simple alkyl chains have been investigated for biological applications. When reported, the cytotoxicity studies of related Ir(III), Re(I), and Ru(II) probes have showed moderate to high cytotoxicity in live cells [46,[49][50][51][52][53]. These complexes are all cationic, which is a feature that is usually associated with enhanced solubility and cellular internalisation.…”
