  • In the contest of a modern green chemistry approach, we firstly tried to substituent the classic peptide synthesis approach with the use of N-carboxyanhydrides in the presence of Hydroxyapatite, a high biocompatible inorganic base. Despite the great results, further developments are necessary for a daily use in laboratory and for our research, we decided to proceed with solid phase or liquid phase synthesis. In the first chapter, the treatment of pain with the use of opioids is introduced. The abuse and misuse of these kind of potent analgesics, led to the necessity of developing new drugs with less side effects. Starting from a previous study, where the introduction of a lactam-like structure in the place of the proline of Endomorphine1, switched the selectivity from MOR to KOR, we designed and synthetized three different libraries by placing a different trans inducer element to gain the desired selectivity and activity forcing the structure to adopt a linear rather than folded position. In the second chapter, we focused on lactate dehydrogenase, an enzyme overexpressed when the cells in hypoxia conditions, like in a tumour mass, need to produce energy through the transformation of pyruvate into lactate. We synthetized different cyclic peptidomimetics, designed to be inhibitors, as powerful tool to contrast cancer cells growing. Biological assays produced satisfactory preliminary results, but further studies are necessary for a definitive output. Finally in the last chapter, the cancer treatment problem is also approached through the design of nanoparticles, able to deliver drugs with efficacy and selectivity. We firstly synthetized silica core nanoparticles, built with toxic peptide sequences conjugated through click chemistry with Pluronic acid and then, in collaboration with Miriam Royo’s research group, we synthetized multivalent platforms for used drugs for the treatment of advanced colorectal cancer.
