Orientation, rotation and solvation of ions in helium nanodroplets

Helium nanodroplets are liquid, finite size, nanoscale helium clusters that have been employed since the 1990s as a matrix for high-resolution spectroscopy of molecules. Spectroscopic studies of ionic species inside helium droplets were not however realise ...

A Pyridine-Based Ligand with Two Hydrazine Functions for Lanthanide Chelation: Remarkable Kinetic Inertness for a Linear, Bishydrated Complex

Lothar Helm, Eva Jakab Toth

To study the influence of hydrazine functions in the ligand skeleton, we designed the heptadentate HYD ligand (2,2',2 '',2 ''-(2,2'-(pyridine-2,6-diyl)bis(2-methylhydrazine-2,1,1-triyl)) tetraacetic acid) and compared the thermodynamic, kinetic, and relaxa ...

Antiangiogenic and Anticancer Properties of Bifunctional Ruthenium(II)-p-Cymene Complexes: Influence of Pendant Perfluorous Chains

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Catherine Marie Amélie Clavel, Emilia Paunescu, Marije Trudi Te Winkel

Two bifunctional ruthenium(II)-p-cymene complexes with perfluorinated side chains, attached via pyridine ligands, have been evaluated in a series of in vitro and in vivo assays. Their effects on human endothelial (ECRF24 and HUVEC) cells, noncancerous huma ...

Inactivation of bacteriophage MS2 with potassium ferrate(VI)

Tamar Kohn, Anne Thérèse Sigstam, Timothy Strathmann

Abstract - Ferrate [Fe(VI); FeO42-] is an emerging oxidizing agent capable of controlling chemical and microbial water contaminants. Here, inactivation of MS2 coliphage by Fe(VI) was examined. The inactivation kinetics observed in individual batch experime ...

New Bisaqua Picolinate-Based Gadolinium Complexes as MRI Contrast Agents with Substantial High-Field Relaxivities

Lothar Helm, Marinella Mazzanti

Two new tripodal heptadentate ligands, H4dpaba (N,N'-bis[(6-carboxypyridin-2-yl)methyl]aspartic acid) and H3mpatcn(1,4-bis(methoxycarbonyl)-7-[(6-carboxypyridin-2-yl)methyl]-1,4,7-triazacyclononane), which bear one or two picolinate pendant arms, have been ...

Proteins as Possible Targets for Cytotoxic trans-Platinum(II) Complexes with Aliphatic Amine Ligands: Further Exceptions to the DNA Paradigm

Paul Joseph Dyson, Angela Casini, Michael Groessl

The reactivity of three cytotoxic trans-PtII complexes bearing aliph. amine ligands, with transferrin and single-stranded oligonucleotides as DNA models, was investigated by ESI-MS and the results obtained are discussed in comparison with cisplatin. Tandem ...

Synthesis and anticancer activity of chalcogenide derivatives and platinum(II) and palladium(II) complexes derived from a polar ferrocene phosphanyl-carboxamide

Paul Joseph Dyson, Anna Katherine Renfrew

The polar phosphinyl carboxamide, 1'-(diphenylphosphino)-1-[N-(2-hydroxyethyl)carbamoyl]ferrocene [I; Z = null; (1)] , reacts readily with H2O2 and elemental S to give the corresponding phosphine oxide I [Z = O (2)] and phosphine sulfide I [Z = S (3)], res ...

Influence of the Arene Ligand, the Number and Type of Metal Centers, and the Leaving Group on the in Vitro Antitumor Activity of Polynuclear Organometallic Compounds

Kay Severin, Christian Hartinger, Alexey Nazarov

Dinuclear ruthenium complexes were shown to exhibit strong antiproliferative properties in human tumor cell lines. In order to extend the structure−activity relationships (SARs), a series of new RuII(arene)X complexes (X = Cl, Br, I) linked by pyridinone-b ...
