Researchers tackle antibiotic-resistant bacteria
When a bacterium becomes more resistant to one antibiotic, it sometimes becomes more sensitive to another. To better understand this interaction, researchers from the Leiden Institute of Biology (IBL) and the Leiden Academic Center for Drug Research (LACDR) under supervision of Daniel Rozen and Coen…

Modified caffeine molecules help medical research move forward
Before researchers can develop targeted drugs, they need to know exactly how a disease works. Biochemist Bert Beerkens created molecules that allow them to find out. He used caffeine as the basis for new molecules that enable research into certain receptor proteins on cells.

Biological Origami at molecular level: folding a single protein
Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

With this algorithm, new medicines can be found more quickly
Did he dare take a gamble with his PhD research? Jeroen Methorst didn’t have to think long about it. It could fail or turn out very well. The latter is the case. Methorst developed a computer system that helps researchers find the protein they need. ‘Our whole group is now using this program.’ Methorst…

Madouc Bergers made her own enzyme inhibitors for her bachelor’s thesis
For her bachelor’s thesis, Molecular Science and Technology student Madouc Bergers synthesized her own molecule that can inhibit the breakdown of sugars. Although most students do not even manage to make one building block, Madouc made three. Partly because of this, she has been nominated for the Science…

Flu stops when you block the enzyme that cleaves off virus particles
A flu virus could cause a pandemic. And then we would be poorly armed because flu viruses are starting to become resistant to flu medications like Tamiflu. Chemist Merijn Vriends successfully worked on an improved version of such medications. He will be awarded his doctorate on September 12th.

Artificial intelligence as the co-pilot for drug discovery
There are more molecules that could conceivably be candidate drugs than there are stars in the universe. How can we ever efficiently identify those molecules? Professor of AI and Medicinal Chemistry, Gerard van Westen: ‘I’m going to use artificial intelligence as the co-pilot to make an automated search.’…

Countering nerve pain caused by chemotherapy with new drug
Nerve pain is one of the most common side effects of chemotherapy. It is therefore one of the biggest reasons for cancer patients to stop treatment early. Darcy Reynolds worked on new drug candidates against this pain during her bachelor's thesis. She developed a new series of molecules that increase…

Antibiotic resistance: an economic problem universities could help to solve
Antibiotic resistance is an economic problem. Pharmaceutical companies cannot earn much from antibiotic research, so they do not invest in it. This makes it important that universities do so, says Ned Buijs.

‘Ultimately, the goal is to develop antibiotics for tuberculosis with a lower risk of resistance’
Tuberculosis stands as one of the most lethal infectious diseases worldwide. A significant challenge in combatting tuberculosis lies in the emergence of antibiotic resistance triggered by genetic alterations, commonly known as mutations. These mutations can diminish the responsiveness to antibiotics,…

Can Parkinson's be stopped by unravelling protein fibres? Anne Wentink finds out with a Vidi grant from NWO
In brain diseases such as Parkinson's and Alzheimer's, proteins clump together to form fibres. ‘Chaperone proteins’ unravel those fibres, but in the test tube biochemist Anne Wentink saw that this can also cause new problems. She is going to find out what happens inside cells to determine what a drug…
