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…

Is is possible to better predict the validity of drug candidates?

Cancer is one of the main causes of death in the Netherlands. Leiden researchers are working to improve the treatment of different types of cancer in order to increase the patient’s quality of life. A better understanding of how cancer develops will make it possible to deliver personalised and precise…

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…

How are new drugs developed? This question is central to the Minor Modern Drug Discovery (MDD), which covers the entire trajectory from disease to drug molecule and vice versa. The various research groups involved offer a complementary and interdisciplinary perspective by connecting the diverse subjects…

The Data-Driven Drug Discovery Network (D4N) is an initiative by researchers from Leiden University and collaborators to join efforts in applying and developing novel techniques from data science to drug discovery and related topics from bioinformatics.

Citizens in multiple crime-ridden countries strongly support the militarization of security—that is, placing the military in charge of traditional policing duties. Yet, we know little about the determinants of such support. Do people approve of militarization even in the face of human fatalities? Political…

Drug-target binding kinetics determine the time course of the central event in pharmacotherapy: Drug-target interaction.

In the research programme Drug Discovery & Safety, we are interested in the efficacy and safety of new drugs and novel means to decipher these aspects. Hence, we employ advanced imaging and high-throughput screening techniques next to computational approaches such as chem- and bioinformatics.

The drug discovery pipeline is used to describe the stages in drug discovery. The earliest stage concerns with the identification of potential targets and molecules ('hits') that can modulate their function, while more advanced stages are about developing these hits into viable experimental drugs and…

Our research in the area of safety sciences aims to increase the mechanistic understanding of cellular toxicity of drugs and, in a broader sense, chemicals.

We focus on a better understanding of the mechanisms of cancer drug resistance and metastasis.

In April, the X-omics initiative was granted 17 million euros from the Dutch Organization for Scientific Research. The subsidy is part of the National Roadmap for large-scale scientific infrastructure, intended to build or renew large-scale research facilities. What new insights will this investment…

Research in this group, headed by Gerard van Westen, focusses on computational methods integrated in different parts of the drug discovery process. More specifically, topics include innovative treatments for cancer, selectivity modeling, translational research, allosteric modulation, drug resistance…

In previous studies at our laboratory it was demonstrated that drug exposure of HepG2 cells can lead to an altered TNFα-induced NF-κB oscillatory phenotype, concurrent with a synergistically increased sensitivity for TNFα-induced apoptosis.
