Effective policy-making requires understanding what truly causes a problem. Only then can policymakers develop targeted interventions that achieve desired outcomes.

Robert Ietswaart does research into gene regulation at the famous Harvard Medical School in Boston. He developed an algorithm to better predict whether a candidate medicine is going to produce side effects. He studied mathematics and physics in Leiden, and gained his PhD in computational biology in…

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…

Cancer is considered the silent pandemic of the 21st century and the second leading cause of death worldwide.

This thesis tackles the urgent challenge of antimicrobial resistance (AMR) through the design of novel antibacterial agents.

There are millions of gene clusters that encode the biosynthesis of bioactive natural products, with the vast majority yet unknown. How can we prioritize them to discover new chemical space for antibiotics? For this we will set up a pipeline based on federated learning (AI), synthetic biology and bioactivity…

Chemotherapy that does not harm the body, but effectively fights cancer cells: that is the goal of chemist Sylvestre Bonnet and his team. During his PhD research, chemist Xuequan Zhou brought that goal a little closer. He developed molecules that, upon injection in the bloodstream, self-assemble into…

Rosan Kuin started her PhD in July at the LACDR under supervision of prof. Gerard van Westen and Dr. Meindert Lamers. She completed a BSc. in Pharmaceutical Sciences at the VU University in Amsterdam in 2017. After that she started two master programs, Drug Discovery & Safety with a specialization in…

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…

This thesis describes the design, characterization and application of dextran based crosslinked network.

As leading cause of death worldwide, cancer is responsible for nearly 10 million deaths in 2020 according to World Health Organization (WHO). Cisplatin and its derivatives are commonly used chemotherapy agents for current cancer treatment in the clinics.

Cardiovascular diseases are among the most frequent causes of death in the world. The main underlying pathology of cardiovascular diseases is the development of atherosclerosis in the medium and large-sized arteries.

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.

PURPOSE: To determine the effect of elasticity on the skin permeation of ketoprofen from surfactant-based vesicular formulations and elastic liposomes.

The Department of Medical Microbiology at Leiden University Medical Center (LUMC) is researching antiviral drugs that could treat and prevent SARS-CoV-2 in various projects. One part of the PanCoroNed project is being led by Martijn van Hemert and involves lab tests into the antiviral effect of molecules…

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

Since the start of the Corona crisis, several COVID-19 related research and teaching projects were started at LACDR. The computational and teaching activities started right away, as well as a large-scale metabolomics screening program by Thomas Hankemeier’s group. Other experimental activities are still…

Nanodiscs are small, disc-shaped structures designed to mimic biological cell membranes, composed of a lipid bilayer stabilized by scaffold proteins. Membrane proteins play crucial roles in essential processes such as nutrient and waste transport, molecular recognition, and cell signalling, making them…

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

In dermatology, there should be a high level of multidisciplinary collaboration among institutes and specialists, Professor of Translational Dermatology, Robert Rissmann, will say in his inaugural lecture on 8 July. He is building an infrastructure that will put pre-clinical and clinical skin research…

The clinical potential of applying synthetic lethality to cancer treatment is famously demonstrated by the BRCA1/PARP1 paradigm: a tumor specific defect in BRCA1 – a component of the DNA double-strand break (DSB) repair pathway homologous recombination (HR) – results in a remarkable sensitivity to PARP1…

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

Drug development critically depends on preclinical models that mimic human physiology, yet traditional two-dimensional cultures and animal models often lack predictive power.

Drug development is hampered by the limited predictive value of conventional 2D culture systems, which fail to recapitulate the complexity of the disease microenvironment and contribute to high clinical attrition rates.

Glucocorticoids (GCs) are widely prescribed as anti-inflammatory drugs due to their well-established immunosuppressive effects.
