A series of ruthenium(II)-arene (RAPTA) compounds were evaluated for their ability to inhibit thioredoxin reductase (either cytosolic or mitochondrial) and cathepsin B, two possible targets for anticancer metallodrugs. In general, inhibition of the thioredoxin reductases was lower than that of cathepsin B, although selected compounds were excellent(More)
The pathological form of prion protein (PrP(Sc)), as other amyloidogenic proteins, causes a marked increase of membrane permeability. PrP(Sc) extracted from infected Syrian hamster brains induces a considerable change in membrane ionic conductance, although the contribution of this interaction to the molecular mechanism of neurodegeneration process is still(More)
Aquaporins (AQPs) are membrane channels that conduct water and small solutes such as glycerol and are involved in many physiological functions. Aquaporin-based modulator drugs are predicted to be of broad potential utility in the treatment of several diseases. Until today few AQP inhibitors have been described as suitable candidates for clinical(More)
Matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs (TIMPs) are the main determinants of tissue remodeling in both physiological and pathological processes. Metabolic processes, which generate oxidants and antioxidants can be influenced by environmental factors such as electromagnetic fields (EMF). We analyzed the effects of EMF on the activity(More)
Poly(ADP-ribose) polymerase (PARP) is a nuclear enzyme which uses NAD+ as substrate and catalyzes the transfer of multiple units of ADP-ribose to target proteins. PARP is an attractive target for the discovery of novel therapeutic agents and PARP inhibitors are currently evaluated for the treatment of a variety of pathological conditions such as brain(More)
The thermodynamics of the binding of the antitumor ammine, amine, and immine complexes of ruthenium(II) and ruthenium(III) to DNA and peptides was studied computationally using model molecules. We performed density functional calculations on several monofunctional ruthenium complexes of the formula [Ru(NH3)5B]z+, where B is an adenine, guanine, or cytosine(More)
Aquaporins (AQPs) are membrane water/glycerol channels with essential roles in biological systems, as well as being promising targets for therapy and imaging. Using a stopped-flow method, a series of gold(III), platinum(II) and copper(II) complexes bearing nitrogen donor ligands, such as 1,10-phenatroline, 2,2'-bipyridine, 4,4'-dimethyl-2,2'-bipyridine,(More)
The optimization of the HPLC procedures and the investigation of the predictive models are generally seen as distinct tasks although they could be both approached by very similar chemometric methods. In this work we used chemometric approaches to both optimize the separation of a non-steroidal anti-inflammatory drugs (NSAIDs) set by isocratic reversed-phase(More)
We propose a new concerted mechanism for the uncatalyzed hydrosilylation of terminal alkenes and alkynes, alternative to the conventional radical-based mechanism. Density functional calculations have been carried out on these and on previously proposed alternative mechanisms for the hydrosilylation of ethylene and acetylene by suitable finite size clusters(More)
The high degree of flexibility characterizing the members of the GST protein family is supposed to be an evolution-resolved feature related to the detoxifying role of these enzymes. Many evidences suggest that overexpression of these enzymes may be implicated in the development of acquired resistance to antitumor agents. Among the most effective GST(More)
