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…

Actinobacteria are well known for the production of bioactive natural products, many of which have applications in the fields of human, animal and plant health. Subject of this thesis are the anthracyclines, glycosylated aromatic polyketides with potent anticancer activity.

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

Researchers of the Leiden University Medical Centre (LUMC) and the Leiden Institute of Chemistry have made an important discovery about the commonly used anti-cancer drug doxorubicin. They have found a way to reduce its side effects without sacrificing the effectiveness of the medication. This is encouraging…

In photoactivated chemotherapy (PACT), a biologically active compound is caged by a light-cleavable protecting group.

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.

Former masterstudent Bio-Pharmaceutical Sciences Maddalena Centanni will be awarded the 2020 Arenberg Coimbra Prize for Erasmus Students. Centanni spent her six month Erasmus exchange at Uppsala Universiy in Sweden where she looked for ways to improve anti-cancer drug dosing.

Providing each cancer patient with the right treatment remains a challenge. Oncode Accelerator aims to change this by innovating the way we develop cancer treatments, thus ensuring the patient is at the heart of the process. Leiden University, the LUMC and other partners will implement this new way…

Last year, chemists Dennis Wander and Hermen Overkleeft contributed to an important discovery about a widely used cancer drug. Their research has now been recognised as Finalist for the PNAS Cozzarelli Prize in the Biomedical Sciences class.

One of the main challenges in the development of an effective anti-cancer vaccine is the generation of an adequate and directed cellular immune response.

How can new compounds relieve cancer patients of severe side effects?

On the 3rd of April, Sebastiaan van der Lubben successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Sebastiaan on this achievement!

Monoacylglycerol lipase (MAGL) is the principal enzyme responsible for hydrolysis of the endocannabinoid 2-arachidonoylglycerol (2-AG). MAGL inhibition provides several potential therapeutic opportunities, including anti-nociceptive, anti-inflammatory and anti-cancer activity.

Researchers from Leiden University Medical Center (LUMC) and Netherlands Cancer Institute (NKI) have discovered how specialised immune cells can detect and remove cancers that are ‘invisible’ to the conventional defence mechanisms of the immune system. Their work has been published in Nature. The findings…

Cytotoxic T-cells (CTLs) are involved in the clearance of viruses and killing of tumor cells.

Leiden PhD student Xuequan Zhou has designed a new promising molecule that efficiently kills cancer cells, but does not harm healthy tissue. The trick: the drug is only active when irradiated with light. Zhou’s new compound does this extra efficiently by cleverly self-organising into nanoparticles.…

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…

Kralen spreken tot de verbeelding. Ze zijn aantrekkelijk en persoonlijk vanwege hun kleuren, materialen, patronen en associaties. Je draagt ze op je lichaam, waar je ze voelt en anderen ze zien. Kralen zijn waardevol en verplaatsbaar, tegelijkertijd reizigers en souvenirs.
