This dissertation contains four works during my PhD. Different biomaterials have been designed based on coiled-coil peptides. These biomaterials have a range of applications, inclusing drug delivery, cell sorting to cell-cell fusion.

Research from the Living Lab is important for society. For example, scientists from the Living Lab discovered that the pesticide thiacloprid is up to 2,500 times more harmful to insects than was thought on the basis of regular lab research. Partly because of this discovery, the European Commission decided…

The effectiveness of the skin barrier underlies the outer layer of the skin: the stratum corneum (SC). However, in several skin diseases this barrier is impaired. In two inflammatory skin diseases, atopic eczema and Netherton syndrome, an increased level of monounsaturated fatty acids (MUFAs) has been…

Oxidation is a common degradation pathway that affects therapeutic proteins and peptides during production, purification, formulation, transportation, storage and handling of solid and liquid preparations. In the present work we review the scientific literature about structural and biological consequences…

Atopic eczema is a skin disease with increasing incidence currently affecting 25% of the paediatric population. In atopic eczema the skin barrier function is reduced. This barrier is formed by the outermost layer of the skin called the stratum corneum (SC). The SC consists of terminally differentiated…

The research presented in this thesis explores the chemotherapeutic potential of metal-based compounds as chemotherapy agents, with an initial focus on the synthesis and DNA interaction studies of platinum and palladium compounds utilizing the [Pt(bapbpy)]2+ scaffold. The study identifies intercalation…

Main challenges in skin vaccination are overcoming the stratum corneum (SC) barrier and targeting the antigen presenting cells (APC) in the epidermis and the dermis.

Patients share valuable advice and experiences with their peers in online patient discussion groups.

The skin protects the body from unwanted influences from the environment as well as excessive water loss. The barrier function of the skin is located in the stratum corneum (SC).

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

Transcutaneous vaccination is attractive because it is non- or minimally invasive, pain free and the site of administration (skin) is easily accessible. What’s more, transcutaneous immunization can lead to a strong immune response owing to the presence of immune-competent cells in the skin.

The research in the Biosyn group is focused on the design, synthesis and function of the four major types of biomolecules: nucleic acids, carbohydrates, peptides and lipids and hybrid structures thereof. These biomolecules and their derivatives are used in drug discovery and chemical biology, to develop…

The goal of pre-clinical development is to bridge the transition from lead compounds to clinical candidates by comprehensively characterizing safety, efficacy, and pharmacological properties. Once a lead compound demonstrates promising activity in disease models, it enters pre-clinical development where…

According to the LUMC, patients experience 30% fewer serious side effects when medication doses are tailored to their DNA.

Alexander Kros studies supramolecular systems in a biological environment. The unifying theme between the projects in my lab is specific molecular recognition, i.e. the intermolecular interaction between complementary molecules with high affinity and selectivity. Studying, imitating and dissecting processes…

Toxys, Leiden University and Leiden University Medical Center have agreed immediately to commercialise and also develop further the ToxProfiler technology invented at the two institutions. ToxProfiler allows for rapid toxicity hazard identification of novel and existing drugs, chemicals, and other substances.…

The receptor nomenclature committee of IUPHAR, the International Union of Pharmacology, has several subgroups. Among these are a few that our division is involved in, those for adenosine, nicotinic acid, and GnRH receptors.

Our educational programmes span the entire spectrum of pharmaceutical education, from training of the next generation drug researchers in the areas of drug design, drug action, and drug use to educating the pharmacists of the future.

In this thesis, the discovery and optimization is described of chemical tools to study the N-acylethanolamine (NAE) biosynthetic pathway.

Cell-based medicinal products (CBMPs) show great promise when it comes to the treatment of genetic disorders. However, there is limited knowledge about CBMP stability during their production, storage, and administration to patients. The main focus of my research is the characterization of CBMPs using…

Cationic peptide amphiphile nanoparticles are employed for co-delivery of immune modulator CpG and antigen. This results in better targeting to the antigen presenting cells and eliciting strong Th1 response, which is effective against the intracellular pathogens.

A very large part of intravenously administered nanoparticles are cleared through the liver. Within the liver, most nanoparticles are thought to be sequestered by macrophages (Kupffer cells). To achieve effective cell-specific targeting of drugs and non-viral gene delivery vectors, improved mechanistic…

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…
