Chelation as a strategy with the potential to overcome multidrug resistance in cancer
(2016-09-02)
According to the World Health Organisation cancer is the second leading cause of death in industrialized countries. In many cases treatment fails due to the development of resistance against multiple (structurally and ...
Structural and functional characterization of G protein-coupled adenosine receptors and the orphan receptor GPR143
(2016-05-24)
The present thesis deals with the characterization of G protein-coupled receptors (GPCRs) and their interaction with modulators on a molecular level. We focused on the structural and functional investigation of different ...
Entwicklung und Charakterisierung von neuen und selektiven Inhibitoren für die Ecto-5’-Nucleotidase
(2016-06-15)
Die Ecto-5’-Nucleotidase (CD73, eN), ein Enzym der Familie der Ectonucleotidasen, wird ubiquitär im Körper exprimiert. Das Enzym wird bei verschiedenen pathophysiologischen Prozessen, vor allem bei Hypoxie, Entzündungsreaktionen ...
Ionic liquids as novel reaction media for the chemical synthesis of peptides
(2016-12-09)
To seek the best solvent in which the peptide can dissolve is usually a serious challenge in peptide chemical synthesis. Ionic liquids, which are liquid below 100 °C, or even at room temperature, showed an outstanding ...
Age-dependent cannabinoid CB1 receptor plasticity and search for histamine H4 receptors in the brain
(2016-10-18)
The aim of this thesis was to examine whether adaptive changes of cannabinoid CB1 receptors occur following their direct and indirect activation through pre-treatment with an exogenous and endogenous cannabinoid ...
Potential of Complementary Methods for the Authentication of Herbal Substances and their Mixtures
(2015-10-22)
Herbal substances and preparations thereof play an important role in healthcare systems worldwide. An essential prerequisite for the safe and effective use of herbal medicines is the unequivocal identification of the plant ...
The allosteric core region of the M2 muscarinic acetylcholine receptor: role for ligand selectivity and action
(2015-09-23)
Muscarinic acetylcholine receptors (mAChRs) are seven transmembrane domain-spanning proteins belonging to the family A of G protein-coupled receptors (GPCRs). In addition to the orthosteric binding site (i.e. the site where ...
Targeting the Final Step of Blood Coagulation: Structure-Activity-Relationship Studies on the Factor XIIIa Inhibitor Tridegin
(2015-09-23)
The prophylaxis and therapy of thrombotic diseases is one of the major columns supporting our continuously increasing life expectancy and health. The transglutaminase factor XIIIa (FXIIIa), which is part of the blood ...
Proteomische Funktionsanalyse humanbiologischer Systeme mittels chemisch modifizierter Proteine
(2016-04-18)
Das humane Proteom unterliegt gegenüber dem eher statischen Genom einem kontinuierlichen Auf- und Abbau. Diese Dynamik zeigt sich durch ein mehrschichtiges Muster an Protein-Protein Interaktionen.
Im ersten Teil ...
