Studies of Glutathione Transferase P1-1 Bound to a Platinum(IV)-Based Anticancer Compound Reveal the Molecular Basis of Its Activation

Paul Joseph Dyson, Ursula Röthlisberger, Wee Han Ang, Pablo Campomanes Ramos

Platinum-based cancer drugs, such as cisplatin, are highly effective chemotherapeutic agents used extensively for the treatment of solid tumors. However, their effectiveness is limited by drug resistance, which, in some cancers, has been associated with an ...

Reactions of Alkynes with [RuCl(cyclopentadienyl)] Complexes: The Important First Steps

Kay Severin, Rosario Scopelliti, Euro Solari, Ursula Röthlisberger, Basile Curchod, Barnali Dutta, Pablo Campomanes Ramos

Cyclopentadienyl-ruthenium half-sandwich complexes with 2-bound alkyne ligands have been suggested as catalytic intermediates in the early stages of Ru-catalyzed reactions with alkynes. We show that electronically unsaturated complexes of the formula [RuCl ...

Reactivity of a rhenium hydroxo-carbonyl complex toward carbon disulfide: insights from theory

Pablo Campomanes Ramos

The reaction mechanism on the formation of the hydrosulfido complex [Re(SH)(CO)(3)(bipy)] via the reaction of [Re(OH)(CO)(3)(bipy)] with carbon disulfide was theoretically investigated at the B3LYP/6-31+G(d, p) (LANL2DZ+f for Re) level of theory taking int ...

Heterogeneous reaction mechanisms of the reduction of nitric oxide on carbon surfaces: a theoretical analysis

Pablo Campomanes Ramos

The mechanism of reaction between NO and two models of carbonaceous materials with active sites was investigated at the UB3LYP/6-31 + G(d) and UM06-2X theory levels. The small model is the anthracene radical and the large one is also a monoradical built wi ...

A Theoretical Study on the Reactivity of a Rhenium Hydroxo-Carbonyl Complex Towards beta-Lactams

Pablo Campomanes Ramos

The mechanism of the reaction between the complex [Re(OH)(CO)(3)(N2C2H4)] and azetidin-2-one or 3-formylamino-N-sulf onatoazetidin-2-one was investigated by using the B3LYP density functional theory methodology in conjunction with the PCM-UAHF model to tak ...
