Syntheses, characterization and DNA-binding studies of ruthenium(II) terpyridine complexes: [Ru(tpy)(PHBI)]2+ and [Ru(tpy)(PHNI)]2+

Celestine blue as a new indicator in electrochemical DNA biosensors

“…This hypochromic effect can be attributed to the formation of CB-DNA complex that decreases the free CB molecules. These results demonstrate an electrostatic binding mode between CB and DNA [37][38][39] which support the results of electrochemical investigation.…”

Synthesis, characterization and DNA binding and cleavage properties of ruthenium(II) complexes with various polypyridyls

“…25 T ph2,3,5,6 of complexes 2 and 3 show upfield shift. T ph2,6 of complex 1 shows small upfield shift, whereas T ph3,5 shows downfield shift.…”

“…26,27 Complexes interact with DNA through electrostatic interaction show lower hypochromicity with no bathochromic shift. 25,28 The electronic spectral traces of the complexes in absence and presence of Herring Sperm DNA are given in Figure 1.…”

“…13 When the compounds interact with DNA electrostatically, no effect on relative viscosity of DNA is observed. 25 The effect of increasing amount of EB and complexes on the relative viscosity of DNA is shown in Figure 2. EB is a well-known classical intercalator.…”

Study of DNA Light Switch Ru(II) Complexes : Synthesis, Characterization, Photocleavage and Antimicrobial Activity

“…They have the potential to insert and stack between the DNA base pairs [4] and further develop into photochemical probes of DNA structure as well as anticancer drugs [5][6][7]. The interactions of CT-DNA with transition metal complexes, which contain planar polycyclic hetero aromatic ligands have been extensively studied [8][9][10][11][12][13][14]. A number of metal chelates are of current interest for important applications in nucleic acid chemistry as probes of DNA structure in solution, reagents for mediation of strand scission of duplex DNA under physiological conditions and chemotherapeutic agents and in genomic research [15][16][17][18].…”
