Treating atherosclerosis with an anti-inflammatory drug. Amanda Foks receives €499.987,00 from the Dutch Heart Foundation to investigate this over the next few years. She will join forces with Tian Zhao from the University of Cambridge. Together they receive 1 million for the research project.

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

Microscopic insight on lipid-based nanomedicine in vivo remains limited to the perception of the knowledge that could be obtained: if we interpret only what we see, then we only believe to know. Although believing to know encapsulates an undefined amount of uncertainty in the exploration of lipid-based…

Currently, more than 80% of drugs are used in an off-label manner in critically ill neonates.

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…

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.

Animal Sciences’ contribution to the Bioactive Molecules research theme includes research on molecules from natural sources, such as plants, insects, and snake venom, with the aim to identify novel anti-cancer, anti-inflammatory, anti-microbial, and anti-diabetic agents.

Media in the Netherlands and abroad reported extensively about the drug research led by Leiden chemist Mario van der Stelt. In this research, Van der Stelt shows which unwanted side-effects a French drug candidate has.

What dose of medicine do you give a child? That depends to a large extent on how quickly their kidneys remove the drug from the blood. For ethical reasons it is impossible to measure this directly in little patients. PhD candidate Sinziana Cristea combined different types of modelling and lots of data…

In the search for new medicines against diseases such as cancer, a Leiden team has developed a new workflow. This approach combines artificial intelligence (AI) with molecular modelling and is suitable for finding unknown and innovative drug structures, the researchers proved.

Leiden chemists have developed a new technique with which they can determine the role of kinases – a group of proteins – in a living cell. This technique makes it easier to find new drug targets for diseases such as cancer and rheumatoid arthritis. The team published the findings in the journal Nature…

This book describes the different approaches for drug delivery to the brain with an emphasis on the physiology of the blood-brain barrier (BBB) and the governing principles and concepts for drug delivery across the BBB

Therapeutic proteins have revolutionized the treatment of many severe diseases like multiple sclerosis, haemophilia, diabetes and many more. Unfortunately, even recombinant proteins with structures (almost) identical to those of their endogenous counterparts often induce the formation of anti drug antibodies…

Utilizing the polymeric platform of polypept(o)ides, this thesis describes synthesis and investigation of novel triblock copolymers to obtain carrier systems with multiple compartments for efficient siRNA delivery. Although the individual microstructure of nanoparticles differs depending on the polymeric…

Leiden chemical biologists led by Dr Mario van der Stelt have developed a method to facilitate the search for new drugs. This method has allowed them to take an important first step in the development of a drug against obesity.

Finding structure in disordered proteins and developing drugs for undruggable diseases: it might sound like mission impossible, but pharmacologist Alireza Mashaghi and his team are right on top of it. Their project was awarded by NWO through the Open Competition Domain Science -XS, a competition that…

The research described in this thesis focused on identifying novel drug targets and synergistic combinations for triple-negative breast cancer (TNBC), a virulent subtype of breast cancer with a dismal prognosis and limited therapeutic options.

An integrated approach of physiological concepts, advanced statistical approaches and large clinical datasets.

Microneedle-based vaccination has several advantages over vaccination by using conventional hypodermic needles.

Bioprinters that enable scientists to engineer complex tissues and organs. It sounds like science-fiction, but not for the scientists of the Alireza Mashaghi lab at the Leiden Academic Centre for Drug Research. The lab has recently been equipped with two state-of-the-art bioprinters: BioX and LumenX+.…

How can we prevent drug-induced liver and kidney damage? PhD candidates Marije Niemeijer and Lukas Wijaya investigated what happens in the cells during the onset of this damage: a stress response. Both focused on a different subtopic and made some interesting discoveries.

Nuclear Magnetic Resonance (NMR) Spectroscopy is a non-destructive analytical technique that is used to study the nature and characteristics of molecules with an atomic level precision. It has a wide range of applications especially in synthetic chemistry, biological and biochemical research groups…

This thesis focuses on enhancing predictions of central nervous system drug exposure using the LeiCNS-PK3.0, a physiologically based pharmacokinetic model.

Global healthcare is on the verge of an antibiotic availability crisis as bacteria have evolved resistance to nearly all known antibacterials. Identifying new antibiotics that operate via novel modes-of-action is therefore of high priority.

Discovering effective new drugs is a long, expensive and uncertain process. Laura Heitman wants to improve this by finding out more about how drugs bind to proteins that play a role in disease. She calls it ‘drug discovery 3.0’. Inaugural lecture on 9 December.

Light can be used to apply forces on single cells. Focused lasers have been used by physicists to tweeze particles and to manipulate them. These so called “optical tweezers” can be used as mechanical phenotyping tools for characterising the mechanics of materials and living objects.

PhD candidate Dennis Wander searches for the best of both worlds. That is to say: a cancer drug that is effective and also has minimal side effects. To this end, he makes new molecules inspired by two existing medicines. And not without result: ‘We have created a new variant that is very promising.’…

Sugar excipients, needed to stabilize medicines, can be unsafe for patients due to an impurity discovered recently by Daniel Weinbuch. ‘The biopharmaceutical industry should now consider new excipient quality criteria for safer drug development,’ he says. PhD defence on 13 December.

On the 6th of March 2023, Santino Regilme presented his work-in-progress titled 'Global Drug Wars: Contested Normative Orders of Peace, Security, and Human Rights'. If the battle against illegal drugs is construed as a war, how is victory in such a war defined and constructed? If the oppositional…

Do medicines arrive in the right amount at the right spot in our brain? By making a model that depicts our brain in small 'brain blocks', Esmée Vendel tries to find an answer to this question. Her new, mathematical model predicts the concentration of medicines in the brain over time and space. Vendel…

It takes years to develop new medicines, from the test tube to trials in humans. During the process it often happens that a drug that seems promising in the initial stage has to be dropped in a later phase. This costs time and money. Leiden University and the LUMC are working closely together to make…

As of April 1, 2018, Erik Danen has been appointed as Professor of Cancer drug target discovery at the Leiden Academic Centre for Drug Research (LACDR). His discipline is cell biology of cancer, in which he focuses on the mechanisms underlying metastasis and therapy resistance.

Monoacylglycerol lipase (MAGL) is the principal enzyme responsible for hydrolysis of the endocannabinoid 2-arachidonoylglycerol (2-AG). MAGL inhibition provides several potential therapeutic opportunities, including anti-nociceptive, anti-inflammatory and anti-cancer activity.

Not taking into account the saturation of drug targets can lead to wrong conclusions about the duration of a drug's action. This is what former PhD candidate Wilbert de Witte writes together with the Leiden professors of pharmacology Meindert Danhof, Piet van der Graaf, and Liesbeth de Lange in Nature…
