Collision-induced dissociation (CID) experiments on protonated carnosine, [carnosine + H](+), with several collision energies were shown to yield eleven different fragment ions with the generation of product ions [carnosine-H2O + H](+) and [carnosine-NH3 + H](+) being the lowest energy processes. Energy-resolved CID showed that at slightly higher collision(More)
Platinum(II)-based anticancer drugs are square-planar d(8) complexes that, activated by hydrolysis, cause cancer cell death by binding to nuclear DNA and distorting its structure. For that reason, interactions of platinum anticancer drugs with DNA have been extensively investigated, aiming at disentangling the mechanism of action and toxicity. Less(More)
Collision-induced dissociation (CID) experiments on the protonated carnosine-oxaliplatin complex, [Carnosine + OxPt + H](+) using several collision energies were shown to yield nine different fragment ions. Energy-resolved CID experiments on [Carnosine + OxPt + H](+) showed that the generation of the product ion [Carnosine - H + Pt(dach)](+) (where dach is(More)
Platinum(IV) complexes are an important class of compounds that can act as prodrugs, and due to their inertness, if correctly designed, they could have low toxicity outside the cancer cell and improve the pharmacological properties of the platinum(II) anticancer agents that are currently used in the clinic. Because of the efforts that are concentrated on(More)
For the synthesis and selection of active platinum-based anticancer drugs that perform better than cisplatin and its analogues, six-coordinate octahedral Pt(IV) complexes appear to be promising candidates as, being kinetically more inert and more resistant to ligand substitution than four-coordinate Pt(II) centers, they are able to minimize unwanted side(More)
The potential use of synthetic metal complexes able to catalyze chemical transformations in living organisms is currently attracting a great deal of attention. Recently, organometallic ruthenium and iridium complexes have revealed an unexpected ability to modulate the redox status of cancer cells. In particular, half-sandwich organoiridium(III)(More)
