Design and Development of Bioactive Molecules

32

The course aims to make the doctoral student acquire the skills necessary to understand the issues inherent in the design and development of bioactive molecules. The course will focus on computational approaches that can facilitate the identification and optimization of hits and lead compounds, and on the development phases of bioactive molecules (from the synthesis laboratory to clinical trials).

The continuous discovery of new biological targets suitable for therapeutic intervention should be accompanied by a high and rapid development of newly discovered ligands or by drug repurposing. From this perspective, computational approaches, such as Docking, molecular dynamics, free energy calculations, and reverse modeling represent efficient tools for obtaining information on structure-function relationships for small molecules and/or natural compounds. Other ligand-based approaches, such as molecular similarity fingerprints, shape methods, pharmacophoric modeling, and QSARs are also widely used in hit/lead identification and optimization.

The rational design is followed by the synthesis of the ligands through the application of innovative synthesis methods (e.g. MAOS), by the use of eco-sustainable processes for the isolation and purification of new compounds (e.g. MPLC, SPE), and finally by the characterization by spectroscopic techniques (e.g. NMR, IR, mass spectrometry).

The last part of the course is dedicated to the preclinical (information on the mechanism of action, its efficacy, and possible toxic effects) and clinical development phases of a bioactive molecule (phase 1-4 trials), up to its approval and placing on the market.

The course hinges on the objectives of the doctorate and the topics may prove valid for using these approaches in a multidisciplinary way (Applied Physics, Chemistry, Biology, Biotechnology, Medicine and Bioengineering, Chemistry and Pharmaceutical Technology).

3D and Super Resolution Microscopy

18

The course addresses PhD students and aims to provide key concepts related to experimental techniques regarding advanced optical microscopy with applications to biology, biophysics, biomedicine and nanotechnologies and related research fields. The course wants to lead students to the full acquisition of knowledge and skills useful for the correct designing and implementation of experiments that involve the acquisition of volumetric and/or high spatial-resolved images (super resolution). The course, after an introduction to the fundamentals of optical microscopy, deals with the theoretical and experimental aspects concerning confocal and multiphoton fluorescence microscopy, light sheet fluorescence microscopy (LSFM) and the most advanced methods of super resolution (Stimulated emission depletion microscopy - STED, Photoactivated localization microscopy - PALM, Stochastic Optical Reconstruction Microscopy - STORM) for the observation of high-resolved three-dimensional reconstruction of living and fixed biological samples. The course aims to provide fundamental skills to identify, using the analyzed microscopy techniques, the involved molecular mechanisms of the specific experimental models of interest for students. Particular attention is due to the physical characteristics concerning the preparation of the samples for a correct three-dimensional visualization and analysis. The course also intends to provide the basis knowledge for the use of specific softwares for analyzing microscopy data and for a quantitative interpretation of the images. Furthermore, the course aims to provide transversal soft skills that result in the critical ability to independently select the appropriate experimental procedures and the suitable advanced microscopy techniques for the correct visualization of the specific sample under examination.

Writing a Scientific Research Project Proposal

6

Scientific research has become more competitive year after year, and finding appropriate funding sources and writing successful project proposals are therefore a core competency for scientists.
In this workshop, students will learn basic principles of good project writing, starting with identifying the suitable funding body to developing the main project idea in order to meet selection criteria. After a preliminary theoretical lecture in which best practices and mistakes to avoid in project writing will be discussed, students will deeply analyze three successful project proposals (i.e. a PON PhD studentship funded by MIUR, a Marie Curie individual fellowship funded by the EU and a research grant funded by Fondazione con il Sud). Eventually, students will review an unsuccessful application, and will be asked to pinpoint weaknesses and suggest improvements. At the end of the workshop, students will be able to:

- Seek funding bodies to support research in their fields;

- Formulate a research hypothesis;

- Design an effective research plan;

- Write a competitive research proposal.

Label-free electrochemical impedance spectroscopy for analytes detection

8

Electroanalytic platforms constitute an established method for the investigation of biological systems. Researches continuously strive to develop rapid, highly selective and low sample consumption analytical assays based on current, charge or potential related to electrochemical processes involving the analyte at the electrode/electrolyte interface. In this scenario, electrochemical impedance spectroscopy (EIS) is gaining more and more interest, as a versatile and broad scope electrochemical tool, permitting in-depth analysis of time-resolved electrochemical processes, based on the current or potential response as a function of potential or current periodic perturbation exciting the electrochemical cell at frequencies typically in the 10-2 Hz - 105 Hz range [1]. The system response is measured as the electrochemical impedance (Z), such value permitting to quantitatively analyse biointerfacial characteristics of the electrode, related to analytically relevant biomolecular interactions (e.g. DNA aptamers-targets, antibody-antigen, cell capture). Differently to classical cyclic voltammetry, EIS permits measurements at predetermined voltages and in the absence of probe labeling. This latter feature is of particular importance since labelling can affect the probes-target affinity, thus making the experiments more complex and time consuming. As to the laboratory activities (four hours), the students will prepare and test electrodes for impedance characterization in aqueous buffer for biomolecules adsorption (e.g. proteins). As a second experience, they will understand how to use EIS to analyse oil-in-water Pickering emulsions, obtaining an electrochemical equivalent circuit based on their acquired data.

Applications of cell culture-based models for the initial characterization of the mechanisms of action of molecules to be adopted in clinical trials

5

The seminar is divided into two parts. The first, held by Dr. Paola Poma, focuses on the presentation of the three phases of clinical drug trials and subsequent post-marketing monitoring with references on pharmacovigilance, phytovigilance and pharma-coepidemiology. Preclinical studies will also be examined, specifying the merits and limits of the use of animal models and presenting the alternative strategies implemented in recent years. Subsequently, Prof. Michela Giuliano will introduce the main in vitro models for preclinical experimentation. In particular, the main types of cell cultures, including primary, continuous, tumor, stem cells up to 3D cultures and organoids, will be presented. The main assays used for the study of toxicity and related biochemical pathways will be described. The seminar is intended for PhD students with non-biological background who use biological models in their PhD research project.
