European XFEL elicits secrets from an important nanogel

An international team at the world's largest X-ray laser European XFEL at Schenefeld near Hamburg has scrutinized the properties of an important nanogel that is often used in medicine to release drugs in a targeted and controlled manner at the desired location in a patient's body. The team has now published the results in the journal Science Advances.

Chemists introduce new copper-catalyzed C-H activation strategy

Inspired by what human liver enzymes can do, Scripps Research chemists have developed a new set of copper-catalyzed organic synthesis reactions for building and modifying pharmaceuticals and other molecules. The new reactions are expected to be widely used in drug discovery and optimization, as well as in other chemistry-based industries.
