STOCKHOLM (Reuters) -Scientists Carolyn Bertozzi, Morten Meldal and Barry Sharpless won the 2022 Nobel Prize in Chemistry on Wednesday for discovering reactions that let molecular building blocks snap together to efficiently create new desired compounds. The technologies known as click chemistry and bioorthogonal chemistry are now used globally to explore cells and track biological processes, the award-giving body said in a statement. “Using bioorthogonal reactions, researchers have improved the targeting of cancer pharmaceuticals, which are now being tested in clinical trials,” it added.
