Medicinal Chemistry

Physicochemical aspect of drugs-protein, protein-protein, drugs-mucus interactions and nanotechnology-based systems to improve drug targeting and delivery.

PART 1

My group is interested in the quantitative biophysical analysis of drug-protein and protein-protein interactions at the molecular level. Biophysical methods are uniquely suited to study the thermodynamics and kinetics of interactions between macromolecules. In our group various biophysical techniques are available to characterize binding and assembly of macromolecules in solution, including fluorescence spectroscopy, UV spectroscopy, stopped-flow kinetics and circular dichroism. These methods can provide the accurate quantitative information about the binding affinity between macromolecules such as proteins and nucleic acids and small molecules. They also allow us to explore the interaction on the molecular level and obtain parameters such as the order of the binding kinetics, the kinetic rate constants and the thermodynamics of the interactions.

Main topics:

• Protein-protein interactions: to study the interaction between macromolecules involved in difefrent diseases
• Drug-protein interactions:  Drugs used in fibrosis cystic therapy and mucin and  photosensitizer used in photodynamic therapy and plasma proteins like HSA and BSA.. Identification of protein as biomarkers through fluorescence "turn on" of specific dyes.
• PNA-DNA interactions: to study from a kinetic point of view this kind of interaction using the stopped flow technique.

PART 2

I apply medicinal chemistry based approaches and nanotechnology-based systems to improve drug targeting and delivery.
Main NaNOtopics:

• gold nanoparticles for radiotherapy and hadrontherapy. Both approaches rely on the damage caused to cells by ionizing radiation, which is released mostly on cancer cells by means of IMRT techniques (Radiotherapy) or energy tuning (Hadrontherapy)  (INFN financed project).
• Carbon nanotubes, carbon nanodots and Halloysite nanotubes used as drug delivery systems.
• Nanostructured-initiators for matrix-free, surface-based mass spectrometry imaging of antitumor drugs in tissues (Cariplo grant)Mass spectrometry imaging (MSI) is one of the latest, rapidly growing, innovative techniques in mass spectrometry (MS). It is used to visualize molecular distribution in a two-dimensional space of a sample attached to an electric conductive steel plate or glass slide. In this context, the goal of this study is the development of specifically designed surfaces for the imaging of antitumor drugs, after administration, in normal organs or tumors tissue of mice, with high spatial resolution and sensitivity.
• protein nanoparticles for antimicrobials release (patent pending, UniTO, PoliMI, UniPV)

 

PART 3

Bac3Gel project: Bac3Gel is a revolutionizing substrate for bacteria culture, solving this problem by mimicking the physicochemical properties of human mucus, where bacterial infections thrive. Bac3Gel is able to model any type of mucus, in healthy or pathological states, with an antibiotic barrier effect similar to physiological effective doses. Allowing efficient screening at the in vitro stage of antibiotic development, cumulatively saving costs later on. This project is made in collaboration with PoliMI and UniPV
