An interdisciplinary team presents a new class of chemical compounds that can be reversibly oxidized and reduced. The compounds known as 'pyrazinacenes' are simple, stable compounds that consist of a ...

Biology is full of molecular machines, such as motor proteins and ATP synthase, that operate self-sufficiently through cycles of oxidation and reduction. A team of human chemists at the University of ...

Oxidants, such as reactive oxygen species (ROS), are known to induce damage to therapeutic proteins. Although cells and tissues usually have antioxidant systems to combat ROS and maintain the balance ...
