Development of an innovative procedure for the chemical analysis of works of art (painting on canvas, wood, fresco etc.) based on the combined use of ToF-SIMS (a surface sensitive technique) and other well established investitgation methods in the field of cultural heritage. Application of this procedure to the set up of restauration interventions on ancient works of art.

Development of antimalarials active against the erythrocytic phase of the Plasmodium falciparum life cycle

The research project will deal with the optimization of the pharmacodynamic and pharmacokinetic properties of the antimalarials recently identified (NF1058 and NF990).

During this project antimalarials will be developed based on a novel pharmacophore and characterized by a mechanism of action related to the interference with the heme detoxification pathways in Pf and devoid of plasmodial protein targets. This approach will guarantee the development of antimalarials endowed with low propensity to induce drug resistance. Accordingly, the selection of one optimized pre-clinical candidate for the treatment of malaria selectively targeting free heme and characterized by a low resistance liability will be one of the main tasks of the project. A second line of research will be aimed at discovering protease inhibitors targeting PfSUB.

Early identification of newborns at high risk of brain injury through a validated biomarkers profile and specific neuro-imaging patterns. A follow up study of clinical and neurodevelopmental outcome in a large cohort study

The present research aims to setting up an OS biomarkers profile correlated with the neuroimaging and neurodevelopmental outcome of the newborn.

Prevention of perinatal brain damage is one of major importance for public health and obviously for individual well being. Cerebral palsy is a group of conditions resulting from damage to the motor and sensory areas, which affect the brain's ability to control movement. Lack of oxygen during labor and delivery, maternal infections, prematurity can contribute to brain injury and cerebral palsy. Phagocyte activation, intrauterine hypoxia, postnatal ischemia-reperfusion generate free radicals (FRs) that play a key role in the developing brain damage.

Development of potential drugs for the treatment of tuberculosis

The compounds object of this research project are structurally analogues of phosphoramidon a well-known inhibitor of Zmp-1 enzyme of M. Tubercolosis, the pivotal role of which has been very recently confirmed by a mouse experimental model of tubercolosis. The metallo-protease activity of  phosphoramidon elicited by its ability  to chelate  zinc ion is the main feature. In the design of novel compounds, characterized by a low molecular weight and a reduced structural complexity, X-ray structure of Zmp-1 protein in complex with its inhibitor along with biochemical studies aimed at the  understanding of the main amino acid involved in the interaction with the substrate have been taken into account. The synthesis of  title compounds is still in progress.

Catalytic mechanism and structural determinants of oxidases, peroxidases and oxygenases for biotechnological and environmental processes

The aim of this research is to address the catalytic properties of different oxidative enzymes for the bio-synthesis of new compounds and for bioremediation. Structure-activity relationship of new natural and synthetic enzymes (Peroxidases, Laccases, Oxidoreductases) is investigated to clarify the biocatalytic mechanism. Since Amino acid radicals were found as  relevant redox active reaction intermediates in enzymatic processes, the combined use of EPR and theoretical calculations proved to be crucial  in the  identification of tryptophan and tyrosine radicals and in the investigation of structure  and site selective assignment of protein-based radicals.

Design, synthesis and applications of new organic sensitizers for non-conventional photovoltaic cells - FOTOSENSORG

The aim of the project is the design, computational characterization and synthesis of new organic dyes to be used for the production of DSSC solar cells that could result to be competitive in comparison with the already available Silicon systems. A life cycle analysis of all the steps constituting the whole DSSC production process on a lab scale is performed to achieve a systematic and complete assessment of environmental impacts and burdens (in energetic and environmental terms) deriving from the process.

Mechanistic structural biology: methodological and biological avances

The focus of the project is the development of new interdisciplinary methodologies, spectroscopic and structural, for the characterization of structure, dynamics and of the intermolecular interactions in solution of proteins and of the comparison with the same systems in the crystal state. The aim is to understand the various states of maturation of the polypeptide towards the final folded state in the different cellular compartments. In this way the study, at the level of mechanistic systems biology, of the assembly of multi-protein complexes is made possible.

Targeting ovarian cancer drug resistance

Ovarian cancer (OC) represents the fifth most common cause of death from cancer in women. The standard first-line treatment is a combination of paclitaxel and carboplatin (DDP). Drug resistanceis commonly observed during therapy. Following the observation of a new inhibition mechanism of the enzyme thymidylatesynthase involved in OC and subject of a FP6 European study participated by us, we conceived this new project aimed to develop molecules for the inhibition of OC cell growth avoiding resistance phenomena.
