The endocannabinoid receptors CB1R and CB2R are involved in a plethora of processes, and consequently are involved in many pathological conditions. Their wide distribution makes the CBRs both an interesting therapeutic target and hard to study.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

β-Lactamases are enzymes that can break down β-lactam substrates, such as antibiotics, preventing the use of these antibiotics for the treatment of various infectious diseases. However, some compounds, β-lactamase inhibitors, can block these enzymes allowing for possible treatments using a combination…

Structure-affinity relationship (SAR) and structure-kinetics relationship (SKR) studies were combined to investigate a series of biphenyl anthranilic acid agonists for the HCA2 receptor.

Premature babies almost always require treatment with medication. Doctors usually determine the dosages based on data from children who were not born prematurely, while preterm infants often develop differently. Medication researcher Aline Engbers investigated three commonly used drugs, focusing on…

Lecture

Historians recently started preliminary research on Leiden University’s role in colonialism and historical slavery. Our knowledge about this is too limited and fragmented. They are looking with fresh eyes at Leiden’s archives and collections. An interview with historians Alicia Schrikker and Ligia G…
