Thioredoxin reductase: A target for gold compounds acting as potential anticancer drugs

The thioredoxin system plays a key role in regulating the overall intracellular redox balance. It basically comprises the small redox protein thioredoxin (Trx), nicotinamide adenine dinucleotide phosphate, in its reduced form (NADPH), and thioredoxin reduc ...

From Pyrone to Thiopyrone Ligands-Rendering Maltol-Derived Ruthenium(II)-Arene Complexes That Are Anticancer Active in Vitro

Christian Hartinger, Alexey Nazarov

Ru(II)-arene complexes with pyrone-derived ligands are rendered active against cancer cells by replacement of the coordinated O,O donor with an S,O donor. The different stabilities of these systems may explain the observed influence of the donor atoms on t ...

Overly long centrioles and defective cell division upon excess of the SAS-4-related protein CPAP

Pierre Gönczy, Gregor Kohlmaier

The centrosome is the principal microtubule organizing center (MTOC) of animal cells. Accurate centrosome duplication is fundamental for genome integrity and entails the formation of one procentriole next to each existing centriole, once per cell cycle. Th ...

Epigenetic Deregulation of DNA Repair and Its Potential for Therapy

Epigenetic silencing of essential components of DNA repair pathways is a common event in many tumor types, and comprise O6-methylguanine-DNA methyltransferase (MGMT), human mut L homolog 1 (hMLH1), Werner syndrome gene (WRN), breast cancer susceptibility g ...

Transferring the Concept of Multinuclearity to Ruthenium Complexes for Improvement of Anticancer Activity

Kay Severin, Alexey Nazarov, Michael Groessl

Multinuclear platinum anticancer complexes are a proven option to overcome resistance of established anticancer compounds. Transferring this concept to ruthenium complexes led to the synthesis of dinuclear Ru(II)-arene compounds containing a bis(pyridinone ...

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 ...

Temperature-Dependent Elasticity of Microtubules

László Forró, Andras Kis, Andrzej Kulik, Sandor Kasas

Central to the biological function of microtubules. is their ability to modify their length which occurs by addition and removal of subunits at the ends of the polymer, both in vivo and in vitro. This dynamic behavior is strongly influenced by temperature. ...

Overcoming multidrug resistance of small-molecule therapeutics through conjugation with releasable octaarginine transporters

Many cancer therapeutic agents elicit resistance that renders them ineffective and often produces cross-resistance to other drugs. One of the most common mechanisms of resistance involves P-glycoprotein (Pgp)-mediated drug efflux. To address this problem, ...
