Para frenar la creciente resistencia del Plasmodium, el parásito causante de la malaria, se necesitan nuevos fármacos con modos de acción diferentes a los de los fármacos actualmente existentes. Esta tesis se centra en ...
Fernández-Llamazares Onrubia, Ana Iris (Date of defense: 2013-12-09)
Backbone N-methylation is becoming an increasingly important tool in peptide drug design, and has been widely used to optimize the activity and selectivity of peptide ligands as a result of conformational modulation. ...
Claudio Montero, Ana Mª (Date of defense: 2012-11-30)
Els anàlegs nucleosídics poden ser utilitzats com a fàrmacs anticancerígens i en teràpies antivirals. Les proteïnes encarregades del reconeixement i translocació dels derivats cap a l'interior cel•lular són els transportadors ...
Zambrana Seguí, Joana Maria (Date of defense: 2013-03-18)
En la present Tesi Doctoral s’han estudiat les reaccions aldòliques amb enolats de titani de cetones quirals derivades de l’èster de Roche, completant un estudi previ amb la reacció aldòlica de propionat. Així, en el ...
Goldflam, Michael (Date of defense: 2013-05-02)
The capacity of proteins to interact with each other rests at the core of biology. Given the ubiquitous nature of these interactions they have attracted the attention of scientists for the development of inhibitors or ...
Tresanchez Carrera, Roger (Date of defense: 2013-06-18)
Molt sovint les seqüències de DNA repetitives adopten conformacions diferents a l'habitual estructura de B-DNA. Aquestes conformacions alternatives afecten esdeveniments genètics fonamentals, com poden ser la replicació, ...
Adrián Izquierdo, Javier (Date of defense: 2012-09-28)
The indiscriminate and/or improper use of veterinary drugs is the cause of potential adverse health effects due to the risk of entering into the food chain and the appearance of residues in food products of animal origin. ...
Velasco Turbau, Javier (Date of defense: 2012-09-27)
L’hepatitis B és una infecció hepàtica potencialment mortal causada pel virus de l’hepatitis B. Es tracta d’una malaltia infecciosa caracteritzada per necrosi hepatocel•lular. L’hepatitis B pot esdevenir en un procés agut ...
Dyachenko, Andrey (Date of defense: 2013-04-15)
In the present thesis we have explored different factors that impede accurate quantitative description of non-covalent protein-protein and protein-ligand interactions and design of new potent and specific binders from the ...
Concia, Alda Lisa (Date of defense: 2013-03-08)
Section 1 (Introduction) is a comprehensive review of the subjects discussed in this thesis: biocatalysis, aldolases and iminocyclitols. It contains a description of the application of dihydroxyacetone phosphate (DHAP) and ...
Blasi Pérez, Daniel (Date of defense: 2013-02-27)
Several drug discovery approaches has been performed to find new compounds able to interact with high affinity with the hormone binding site of the homotetrameric protein transthyretin (TTR), and stabilize this tetramer, ...
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” ...
