We have used ion mobility-mass spectrometry combined with molecular modeling for the separation and configurational analysis of three low-molecular-weight isomeric organoruthenium anticancer complexes containing ortho-, meta-, or para-terphenyl arene ligands. The isomers were separated using ion mobility based on traveling-wave technology and the(More)
The synthesis and characterization of ruthenium(II) arene complexes of the general formula [(eta(6)-arene)Ru(XY)Z](+), where arene = p-cymene (p-cym), hexamethylbenzene (hmb), or biphenyl (bip), XY = o-phenylenediamine (o-pda), o-benzoquinonediimine (o-bqdi), or 4,5-dimethyl-o-phenylenediamine (dmpda), and Z = Cl, Br, or I, are reported (complexes 1-6). In(More)
We have compared the cancer cell cytotoxicity, cell uptake, and DNA binding properties of the isomeric terphenyl complexes [(eta(6)-arene)Ru(en)Cl](+), where the arene is ortho- (2), meta- (3), or para-terphenyl (1) (o-, m-, or p-terp). Complex 1, the X-ray crystal structure of which confirms that it has the classical "piano-stool" geometry, has a similar(More)
We studied the thermodynamic properties, conformation, and recognition of DNA duplexes site-specifically modified by monofunctional adducts of Ru(II) complexes of the type [Ru(II)(eta(6)-arene)(Cl)(en)](+), in which arene=para-, meta-, or ortho-terphenyl (complexes 1, 2, and 3, respectively) and en=1,2-diaminoethane. It has been shown (J. Med. Chem. 2008,(More)
The synthesis and characterization of ruthenium(II) arene complexes [(eta(6)-arene)Ru(N,N)Cl](0/+), where N,N = 2,2'-bipyridine (bipy), 2,2'-bipyridine-3,3'-diol (bipy(OH)(2)) or deprotonated 2,2'-bipyridine-3,3'-diol (bipy(OH)O) as N,N-chelating ligand, arene = benzene (bz), indan (ind), biphenyl (bip), p-terphenyl (p-terp), tetrahydronaphthalene (thn),(More)
