New clues for asthma treatment

(PhysOrg.com) -- New information that could help in the fight against asthma has been obtained by an international collaboration of scientists utilizing the U.S. Department of Energy’s Advanced Photon Source at Argonne ...

Computer simulation of receptors reveals a new ligand-binding site

Using a computer simulation of an important receptor, EPFL scientists have discovered a novel binding site for natural ligands and drugs. The new site might be present on other receptors and can be exploited in novel treatments ...

Understanding a cell's 'doorbell'

A multi-institutional project to understand one of the major targets of human drug design has produced new insights into how structural communication works in a cell component called a G protein-coupled receptor (GPCRs), ...

Scientists solve structure of complement C5a receptor

Scientists at Heptares Therapeutics have published the first high-resolution X-ray crystal structure of the complement C5a receptor (a G protein-coupled receptor, GPCR) binding a small molecule allosteric antagonist.

Researchers map trends in drug development

From a drug perspective, G protein-coupled receptors are the most utilised cell receptors in the body. They are uniquely accessible at the cell surface, and a third of all drugs sold in the US target them.

How receptors for medicines work inside cells

G protein-coupled receptors are the key target of a large number of drugs. Würzburg scientists have now been able to show more precisely how these receptors act in the cell interior.

X-ray laser brings cellular messengers into focus

Last year's Nobel Prize in Chemistry – shared by Stanford School of Medicine Professor Brian Kobilka and Robert Lefkowitz of Duke University – recognized groundbreaking research in G protein-coupled receptors (GPCRs). ...
