Description
- The data presented in this thesis was generated using molecular biology, protein chemistry and X-ray crystallography techniques. However, while the methodologies employed are essentially the same, the research work presented here refers to two different proteins, which are part of different research projects in the laboratory. For this reason, the content of this thesis is divided in two independent parts, each provided with an introduction and a general overview of the research topic and state-ofthe- art, a materials and methods section discussing the techniques used and the protocols followed, and a section where the results are presented and discussed in detail. The first half of the thesis deals with the structural characterization of the complex between human E-cadherin and three different small molecule potential inhibitors identified via a fragment-based drug discovery (FBDD) screening campaign that was conducted using a library of commercially available small fluorinated chemical fragments. For this screening phase, we used 19F-NMR as readout. The NMR experiments were done by our collaborator Dr. Marina Veronesi at the D3 PharmaChemistry division of the Italian Institute of Technology (IIT) in Genova (Italy). Functional cell adhesion assays to validate the inhibitory effects of the fragments thus identified were carried out in collaboration with Prof. Frédéric André at the University of Marseille (France). The second half of the thesis describes the structural characterization of Plasmodium falciparum Choline Kinase (PfChoK), an important pharmaceutical target in the fight against malaria, as well as the biochemical characterization of a library of potential inhibitors of PfChoK. These inhibitors were synthetized in the group of Prof. Luisa Carlota López-Cara at the Department of Pharmaceutical and Organic Chemistry of the University of Granada (Spain) in the framework of an ongoing collaboration between the two groups.
