For his ground-breaking chemical biological research, a VICI-grant has been awarded to Mario van der Stelt, professor of Molecular physiology at Leiden University. In a new research line, he aims to discover binding sites for new medicines against inflammations in the brain.

Mario van der Stelt has been appointed Professor of Molecular Physiology at the Leiden Institute of Chemistry with effect from 1 November 2017.

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.

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…

Cancer is the leading cause of death in the Netherlands, and, with over 100 different types of cancer, it’s not a simple disease. Today, skin, breast, lung, prostate and colon cancer are the most diagnosed forms. Therefore, the discovery and development of new drugs has the ability to significantly…

De decentralisaties van de zorg aan langdurig zieken en ouderen, jeugdzorg, en werk en inkomen die vanaf 2015 zijn doorgevoerd in Nederland hebben geleid tot een transitie van een centraal naar een lokaal stelsel van zorg en welzijn. Deze transitie beoogt zorg en ondersteuning dichter bij de inwoners…

Multiple Sclerosis, Parkinson’s and Alzheimer’s disease are the most common neurodegenerative disorders. Unfortunately, no effective treatments are currently available to halt the progression of these neuroinflammatory diseases [1].

Activity-based protein profiling (ABPP, also termed chemical proteomics), is one of the pillars of chemical biology, and at LED3 we have taken it to the next level. ABPP allows the assessment of protein function in live cells and tissues, which means that the activity of a complete protein family can…

The drug BIA 10-2474 inhibits fatty acid amide hydrolase (FAAH), a lipase that degrades a specific endocannabinoid. On the basis of this activity, BIA 10-2474 was being developed as a potential treatment for anxiety and pain. In a phase 1 trial of the drug, one subject died, and four others suffered…

The aim of the research described in this thesis was to use structure-based design to optimise multiple properties of aryl sulfoxide monoacylglycerol lipase inhibitors as anti-inflammatory analgesics.

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…

In Democratie en totalitarisme zijn de invloedrijkste opstellen van de Franse denker Claude Lefort samengebracht. Lefort laat overtuigend zien dat de kwetsbaarheid van de democratie juist ook haar kracht is. Voor democratie is essentieel dat de macht als ‘lege plaats’ verschijnt. Zij mag slechts tijdelijk…

Molecular Physiology is a research group at the Leiden Institute of Chemistry dedicated to the design, synthesis and application of chemical tools to study important biological and biomedical questions. The group is headed by Prof. Dr. Mario van der Stelt and includes the research lines of Assistant…

The cannabinoid CB2 receptor (CB2R) represents a promising therapeutic target for various forms of tissue injury and inflammatory diseases. Although numerous compounds have been developed and widely used to target CB2R, their selectivity, molecular mode of action and pharmacokinetic properties have…

N-acylethanolamines (NAEs), including N-arachidonoylethanolamine (anandamide, AEA), N-palmitoylethanolamine (PEA) and N-oleoylethanolamine (OEA), are signaling lipids that play an important role in different physiological process.

The disease acute myeloid leukemia (AML) is characterized by fast progression and low survival rates.

Diacylglycerol lipases (DAGLα and DAGLβ) convert diacylglycerol to the endocannabinoid 2-arachidonoylglycerol. Our understanding of DAGL function has been hindered by a lack of chemical probes that can perturb these enzymes in vivo.

This thesis explored the molecular pharmacological mechanisms of targeting CB2R via investigation of novel drug discovery concepts such as target binding kinetics, allosteric modulation and biased signaling.

This thesis describes the use of an activity-based proteomics method to study the endocannabinoid system.

Chemical tools to monitor drug-target engagement of endogenously expressed protein kinases are highly desirable for preclinical target validation in drug discovery. Here, we describe a chemical genetics strategy to selectively study target engagement of endogenous kinases.

Endocannabinoids are lipid messengers that modulate various physiological functions by activating the cannabinoid CB1 and CB2 receptors. While the metabolism of endocannabinoids and their action at the CB receptors is fairly well studied, the molecular mechanisms governing their release and transport…

Our students and public and private organisations have much to offer each other. To connect students with organisations, FGGA facilitates this through an internship and traineeship platform: TRAIL.

Covid-19 is een disruptieve ontwikkeling die hier en nu veel vraagt van zorgprofessionals, bestuurders en managers. Hoewel de crisis nog volop bezig is, is nu al duidelijk dat het Coronavirus een blijvende impact zal hebben op zorginstellingen en fundamentele vragen oproept over hoe we onze zorg optimaal…

The spindle-assembly checkpoint (SAC) is a safety mechanism which secures accurate chromosome segregation during mitosis.

Diacylglycerol lipases (DAGLα and DAGLβ) are responsible for the biosynthesis of the endocannabinoid 2-arachidonoylglycerol (2-AG) in the brain and peripheral tissues. Selective DAGLβ inhibitors have been proposed as a potential treatment for inflammatory diseases with reduced potential for central…

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.

Do objectively correct solutions to ethical dilemmas exist? Or is ethics always a matter of your opinion against my opinion? How do you know what to do? What kind of thing is ethics anyway? Can you be an expert in ethics?
