octahedral [Ni(phen)2(dppz‐idzo)]2+ and [Co(phen)2(dppz‐idzo)]3+ complexes have been synthesized and characterized by CHN analysis, electrospray ionization‐MS, nuclear magnetic resonance, and UV–Vis spectra. The DNA‐binding ability of these complexes was spectrophotometrically, hydrodynamically, and electrophoretically evaluated which indicated that they strongly intercalate into the DNA double helix

Polymorphic DNAG‐quadruplex recognition has attracted great interest in recent years. The strong binding affinity and potential enantioselectivity of chiral [Ru(bpy)2(L)]2+ (L=dipyrido[3,2‐a:2′,3′‐c]phenazine, dppz‐10,11‐imidazolone; bpy=2,2′‐bipyridine) prompted this investigation as to whether the two enantiomers, Δ and Λ, can show different effects on diverse structures with a range of parallel
Inert cationic iridium(<scp>iii</scp>) complexes with phenanthroline-based ligands: application in antimicrobial inactivation of multidrug-resistant bacterial strains
New iridium complexes with phenanthroline-based ligands show great potential as antimicrobials, being even more effective than the broad-spectrum antibiotic norfloxacin in Gram positive bacteria.

architecture, implying potential applications in anticancer therapeutics. Both the “lightswitch” effect and the structure stabilization ability of [Ru(bpy)2dppz-idzo]2+ were found to be superior to the well-known DNAmolecular “lightswitch” [Ru(bpy)2dppz]2+. Finally, a “sandwich-like” binding model was proposed on the basis of molecular docking simulations.
