Femtosecond UV Studies of the Electronic Relaxation Processes in Cytochrome c

Majed Chergui, Andrea Cannizzo, Olivier Christian Bräm, Cristina Consani

We report on an experimental study with UV and visible ultrafast time-gated emission and transient absorption of the early photodynamics of horse heart Cytochrome c in both ferric and ferrous redox states. A clear separation in time and energy of tryptopha ...

Anticancer activity of new organo-ruthenium, rhodium and iridium complexes containing the 2-(pyridine-2-yl)thiazole N,N-chelating ligand

Paul Joseph Dyson, Angela Casini, Fabio Edafe

The dinuclear dichloro complexes [(η6-arene)2Ru2(μ-Cl)2Cl2] and [(η5-C5Me5)2M2(μ-Cl)2Cl2] react with 2-(pyridine-2-yl)thiazole (pyTz) to afford the cationic complexes [(η6-arene)Ru(pyTz)Cl]+ (arene = C6H6 (1), p-iPrC6H4Me (2) or C6Me6 (3)) and [(η5-C5Me5)M ...

Novel Ruthenium Complexes with Sterically Demanding Cyclopentadienyl Ligands : Syntheses, Reactivity and Catalytic Applications

Barnali Dutta

Investigations of ruthenium halfsandwich complexes have mostly focused on Cp and Cp* based derivatives due to the availability of easily accessible starting materials. However, it is interesting to have complexes with substituted cyclopentadienyl ligands i ...

Binding of Organometallic Ruthenium(II) Anticancer Compounds to Nucleobases: A Computational Study

Ursula Röthlisberger, Ivano Tavernelli, Christian Gossens

The reaction of the anticancer compound (eta(6)-benzene)Ru(en)(OH2) (1) toward the nucleobases guanine, adenine, and cytosine is studied computationally using DFT/BP86 calculations. The aqua leaving group of such compounds is known to undergo ligand ...

Modulating the Near-Infrared Luminescence of Neodymium and Ytterbium Complexes with Tridentate Ligands Based on Benzoxazole-Substituted 8-Hydroxyquinolines

Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy

An improved synthesis of 2-(2′-benzothiazole)- and 2-(2′-benzoxazole)-8-hydroxyquinoline ligands that combine a tridentate N,N,O-chelating unit for metal binding and extended chromophore for light harvesting is developed. The 2-(2′-benzoxazole)-8-hydroxyqu ...

Homo- and Heterodinuclear Helicates of Lanthanide(III), Zinc(II) and Aluminium(III) Based on 8-Hydroxyquinoline Ligands

Jean-Claude Bünzli, Frédéric Gumy

Homonuclear helicates with rare-earth-metal(III) ions or heteronuclear derivatives with rare-earth-metal and aluminium or zinc centres are obtained in alkali-metal-templated selfassembly processes from isobutenylidene- bridged homoditopic bis(2-carb-Gamido ...

Studies on the reactivity of organometallic Ru-, Rh- and Os-pta complexes with DNA model compounds

Paul Joseph Dyson, Rosario Scopelliti, Christian Hartinger, Antoine Dorcier

The reactions of arene-metal complexes (arene = p-cymene, benzene or pentamethylcyclopentadienyl, metal = Ru, Rh or Os), including 1,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decanephosphine (pta) and chloro co-ligands, with 9-methylguanine, adenine, and a ser ...

Carbohydrate-metal complexes and their potential as anticancer agents

Paul Joseph Dyson, Christian Hartinger, Alexey Nazarov

A review. Platinum complex-based chemotherapy is one of the major treatment options of many malignancies. Although severe side effects occur, and only a limited spectrum of tumors can be cured, Pt compds. are used in every second therapy scheme. Thus, many ...
