    Ros Simó, Enric (Date of defense: 2020-12-16)

    The present doctoral thesis has been devoted to the use of 1,2,4,5-tetrazines as potential tools for chemical biology. Tetrazines have become extremely interesting functionalities due to their ability ...

    Syntheses of Protein Degraders and Compounds for Targeted Drug Release 

    Donoghue, Craig (Date of defense: 2019-07-24)

    The thesis consists of two main projects: a) the development of a novel strategy to gain genetic control with spatiotemporal precision, and b) the optimisation of inhibitors of the protein kinase p38α, which has a major ...

    Synthesis and versatile applications of oligoethylene glycol dendrons using click chemistry 

    Fransen, Peter (Date of defense: 2013-12-05)

    Dendrimers are a class of globular highly branched macromolecules with precise architecture. They consist of a multivalent surface with functional group, a core unit where branching starts, and the interior is made of ...

    Synthesis of biaryl bicyclic peptides for recognition of protein surfaces 

    Garcia Pindado, Júlia (Date of defense: 2017-05-12)

    The present thesis is based on the development and optimization of a solid-phase strategy to prepare biaryl bicyclic pentapeptides. Suzuki-Miyaura cross-coupling reactions were used to obtain the biaryl bridge. The metholodogy ...

    Synthesis of Highly Structured and Receptor-Selective Tetradecapeptidic Analogs of Somatostatin: Fine-tuning the non-covalent interactions among their aromatic residues 

    Martín-Gago, Pablo (Date of defense: 2013-10-11)

    Somatostatin, a peptidic hormone also known as somatotropin release-inhibiting factor (SRIF), is implicated in multiple biological functions, mediated by direct interaction of the peptide with a family of structurally ...

    Synthesis, structural elucidation and biological evaluation of Pipecolidepsin A and Phakellistatin 19 

    Pelay Gimeno, Marta (Date of defense: 2013-02-15)

    Pipecolidepsin A is a cyclodepsipeptide produced by a Homophymia marine sponge that has shown interesting anticancer properties against several human cancer cell lines. From a structural point of view, it is a “head-to-side-chain” ...
