- From enzymatic function to drug discovery -
We are a research group focused on the understanding of function and inhibition of pharmaceutically relevant enzymes and functionalized nanoparticles. Within the group, we develop and apply computational methods for multiscale molecular modeling and simulations, which are fully integrated with medicinal chemistry and structural/molecular biology. This multidisciplinary approach allows to design, synthesize and test promising compounds potentially endowed with the desired pharmacological effect to treat primarily cancer, neurological disorders and inflammatory-related diseases.

Our latest stories:
-> Characterization of our novel class of selective NKCC1 inhibitors for the treatment of CNS disorders
Intracellular chloride concentration is defective in several neurological disorders. In previous collaborative works we have shown that correction of intracellular chloride concentration through NKCC1 inhibition with our lead compound rescues core Down Syndrome symptoms. In this new collaborative effort we describe in depth the discovery and extensive characterization of our new chemical class of selective NKCC1 inhibitors. Our results further strengthen the potential of our inhibitors for the treatment of brain disorders characterized by defective intracellular chloride concentration.

-> Elucidating the functional role of metal ion trafficking in a fundamental metallozyme
Recent RNase H1 structures unexpectedly captured multiple metal ions transiently bound near the two metal ion active site. Using state of the art simulation techniques we investigated the functional implications of the exchange of these newly found metal ions at the reaction center. This exciting collaboration lead to the finding that the metal ions' role is crucial for reactant alignment and leaving group departure, also that the solution’s ionic strength tightly regulate the metal ions’ trafficking.

-> Understanding the outer coating monolayer of nanoparticles to increase nanozyme efficiency
Gold nanoparticles functionalized with Zn(II) complexes cleave phosphate esthers and nucleic acids, similarly to metallonuclease enzymes. To elucidate the reaction mechanism of these nanocatalysts we have used and integrated approach of microsecond long simulations along with NMR experiments, to investigate the structure and dynamics of the outer coating monolayer of these nanoparticles. This collaborative effort lead to the finding that these nanozyme's mechanism mimics two-metal-ion enzymes for nucleic acid processing.

-> Using a hybrid experimental-computational approach for the study of guanidium-functionalized gold nanoparticles and neutral phospholipid bilayers
For the advancement of nanomedical applications, it is necessary to understand and control the interactions between nanoparticles and biological entities. Specifically, nanoparticles that are able to directly target membranes are an important leap forward. Here, we have shown that guanidium-coated gold nanoparticles can bind non-disruptively to neutral liposomes, in contrast to nanoparticles decorated with other positively charged headgroups.

Understanding catalysts is fundamental for the design of catalytic systems, enzyme inhibitors or drugs. First principles MD is a powerful technique that combines the description of both nuclear and electronic rearrangements during catalytic reactions. Recently, this tool has only become increasingly attractive due to improvements in accuracy, computing power and algorithmic advances.
