During the congress of the Royal Dutch Association for the Advancement of Pharmacy (Koninklijke Nederlandse Maatschappij ter bevordering der Pharmacie, KNMP) Jacqueline Gerritsen, former student Bio-Pharmaceutical Sciences at Leiden University, was awarded the KNMP student prize.

Research in this group, headed by Gerard van Westen, focusses on computational methods integrated in different parts of the drug discovery process. More specifically, topics include innovative treatments for cancer, selectivity modeling, translational research, allosteric modulation, drug resistance…

The Oncode Institute is a new international network organisation that focuses on making sure that new scientific findings on cancer are implemented in patients as rapidly as possible. Two young female researchers at Leiden University have been selected to join Oncode: Laura Heiman (Leiden Academic…

On Friday May 3rd 2013 NWO has announced that Dr. Mario van der Stelt, Division of Bio-Organic Synthesis (LIC) and Dr. Laura Heitman, Division of Medicinal Chemistry (LACDR), have been awarded with an ECHO-STIP grant for their project, entitled: “Novel target engagement biomarkers for better drug ca…

There are many complex links in the chain that provides patients with new drugs: from fundamental science, to clinical tests, to production. The entire chain can be found in Leiden. The University, the Leiden University Medical Center (LUMC) and the businesses at the Leiden Bio Science Park (LBSP) work…

Professor of Pharmacochemistry Ad IJzerman has won the Nauta Award for his years of research into signal processing proteins that are interesting for the development of new medications: G protein coupled receptors. The prize is awarded every two years for services to pharmacochemistry and chemical b…

Laura Heitman has been awarded a VIDI grant for her innovative drug research. Heitman strives to optimize a drug’s binding kinetics at its target in order to ultimately fight diseases effectively. She even pleads for a paradigm shift in drug discovery.

Potential drugs that seem promising in the lab, but don’t show any activity in a person: they cost the industry an incredible amount of time and money. That’s why Indira Nederpelt focuses on a more efficient search for new drugs in her PhD, by determining the kinetics of a potential drug earlier on…

Pharmaceutical research should make more use of data science, says Gerard van Westen, postdoctoral fellow at the Leiden Academic Centre for Drug Research (LACDR). ‘If we want to have better drugs, we should start with data.’

The cannabinoid receptor type 2 (CB2R) is associated with several inflammatory diseases with an unmet medical need (e.g. Alzheimers, multiple sclerosis, reumatoid arthritis). Development of new chemical biology strategies to study this protein is essential to aid future development of drugs for these…

During the course of drug discovery translational steps are made.

One of the main challenges in the development of an effective anti-cancer vaccine is the generation of an adequate and directed cellular immune response.

In this study, we evaluated the influence of supercritical carbon dioxide (scCO2) spray drying conditions, in the absence of organic solvent, on the ability to produce dry protein/trehalose formulations at 1:10 and 1:4 (w/w) ratios.

Chapter 2 describes a post-synthetic methodology to introduce a fluorescent label in highly lipophilic, Pam3Cys based conjugates.

Both psoriasis and atheroslcerosis are diseases characterized by a chronic and systemic inflammatory profile with local lipid disturbances that alter the barrier function of the skin (psoriasis) and cause the development of atherosclerotic plaques (atherosclerosis).

The barrier function of the skin is primarily provided by the stratum corneum (SC), the outermost layer of the skin. Skin barrier impairment is thought to be a primary factor in the pathogenesis of atopic eczema (AE).

PURPOSE: In the present study we investigated the root-cause of an interference signal (100-200 nm) of sugar-containing solutions in dynamic light scattering (DLS) and nanoparticle tracking analysis (NTA) and its consequences for the analysis of particles in biopharmaceutical drug products.

The purpose of this study was to investigate the formation and growth kinetics of complexes between proteins and oppositely charged polyelectrolytes.

In this thesis, the focus lies on studying glucocorticoid receptor dynamics in living cells with the aim of understanding how this transcription factor finds its DNA target sites to regulate transcription.
