To explore the potential of marine microorganisms as producers of novel antimicrobial agents and as bioprotectants in aqua- and agriculture, using an integrative, ecology-based strategy for bioprospecting.

The Chemical Probe Facility is part of the Leiden Early Drug Discovery & Development (LED3) center. Activity-based protein profiling (ABPP) is one of the pillars of chemical biology. ABPP determines the activity of entire protein families in living cells and tissues under physiological conditions, such…

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.

During the course of drug discovery translational steps are made.

In your first year at LUC you gain the basic knowledge and lay the foundation and skills for your specialization in year two and three.

This project studies travel writing about the Dutch East Indies written between 1800 and the end of the Second World War. By analyzing both Dutch travel texts and Indigenous travel texts in Javanese and Malay, it presents a new, double-voiced perspective on (the historiography of) the Dutch colonial…

What would a university be without its students? In 2025, we will celebrate 450 years of studying with an exhibition showcasing our students from the past centuries. How did they study in the past? And how do they study now? This outdoor exhibition will be on display from 23 April at the Hortus bota…

The opening of the Academic Year 2025-2026 took place on Monday 1 September 2025 in the Pieterskerk church.

If spending three years at university and following the entire Dutch Studies programme is not an option for you, we offer an alternative. We have created a challenging one-year programme in which you will learn to speak Dutch and delve into Dutch culture. This programme is less comprehensive, and allows…

Can small molecule drugs restore the immune system’s ability to fight tuberculosis by boosting autophagy?

In the research programme Microbial Sciences we perform state-of-the-art research in the field of biotechnology and microbial sciences.

In this work, we attempt to answer the question:

Chemical biology research at the Leiden Institute of Chemistry is aimed at understanding biological processes at the molecular level to strengthen the knowledge base of human health and disease. The approach to achieve this goal is a fundamental chemical one; with the aid of chemical probes biological…

Biologist Freek Vonk had already appeared in the Time Warp programme, where he was shown milking a snake for its venom, which he needed for his doctoral research. On Friday 18 September, he explained his fascination for snakes to Matthijs van Nieuwkerk in ‘De wereld draait door’, a Dutch news and entertainment…

In the summer of 2010, a special archaeological find resurfaced when plans to redevelop the Paardenmarkt, a parking lot in the historic city center of Alkmaar, began.

Where exactly on the surface of a catalyst do the chemical reactions occur? Until now, it has always been a challenge to identify the exact locations of these ‘active sites’. In a new article in Nature, Leiden chemists helped their international colleagues reveal new insights into this issue. Their…

From a successful April Fool’s prank and alumni love stories to a fabulous float on 3 Octobe: these were the highlights of our year on our social media channels. Hope you’re following us?

In 2019 Leiden University was 444 years old. This special birthday called for a special celebration. We celebrated this milestone with the residents of Leiden and The Hague. In, with and for these two cities.

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

Ahead of the times? We’ve been that for over 450 years. As the oldest university in the Netherlands, we’ve sailed through the centuries with our sights fixed firmly on the society of the future. Our anniversary in 2025 was a chance to look back too. A chance to celebrate the impact of our research and…

Designing and synthesizing high-affinity ligands for a given drug target have always been among the more important challenges in the drug discovery process.
