A tantalizing concept that has emerged in our recent research is binding kinetics. An important parameter is residence time (RT), a direct reflection of how long a drug stays bound to its target. This parameter is of crucial importance, because drug action lasts only as long as the receptor-ligand complex…

Drug-target binding kinetics determine the time course of the central event in pharmacotherapy: Drug-target interaction.

The present thesis focuses on the pharmacological concept of drug-target interaction, which dates back to the beginning of modern pharmacology.

It is estimated that approximately 30% of all proteins require a metal to function. Investigating the relationship between metal-binding and peptide/protein folding allows us to uncover fundamental rules for creating metallo-peptides and proteins, which in turn leads to the creation of new structures,…

Detection of cerebral beta-amyloid (Abeta) by targeted contrast agents remains of great interest to aid the in vivo diagnosis of Alzheimer's disease (AD). Bis-styrylbenzenes have been previously reported as potential Abeta imaging agents.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

During the course of drug discovery translational steps are made.

Leiden University is ending the experiment with the Binding Study Advice in the second year of the bachelor's programme (BSA 2) with immediate effect. Under the terms of BSA 2, students were required to obtain 90 credits within two years, including their first-year diploma.

Intelligence scholars have been struggling to find the conditions under which international intelligence cooperation occurs. Most focus on transactional motives and guaranteed returns, the so called ‘Quid pro Quo’. At the same time, trust is often mentioned as one of the foremost conditions, yet it…

In this thesis I describe the results of Pulsed Interleaved Excitation and Fluorescence (Cross) Correlation Spectroscopy (PIE-F(C)CS) combined with single-pair Förster Resonance Energy Transfer (spFRET) used to study dynamics in single nucleosomes, which depends on subtle differences in the length of…

Adenosine is an endogenous ligand which exerts its action by activating adenosine receptors (ARs), while its circulating levels are controlled via a variety of mechanism and proteins, amongst others the equilibrative nucleoside transporters (ENTs).

At Leiden University we believe it is important that you receive the right kind of support in your choice of study and while you study. This is why we use what we call the ‘Leiden study system’ to help you make a success of your study from start to finish.
