Researchers study the possible use of carboranes

Researchers study the possible use of carboranes: "When protein plaque builds up in the blood, it can result in serious diseases such as heart disease and Alzheimer's.

Cyclooxygenase (COX) inhibitors, a class of drugs under investigation for the treatment of one cause of plaque build-up, also exhibit negative side effects.

Researchers in the International Institute of Nano and Molecular Medicine at the University of Missouri-Columbia are studying the possible use of carboranes, which are clusters of boron and carbon atoms, to prevent such side effects. These boron-rich clusters are substituted for carbon-based benzene rings commonly found in pharmaceuticals of all types, including COX inhibitors, which give unwanted side effects.

COX activity is seen in common nonsteroidal anti-inflammatory drugs like aspirin and ibuprofen. However, prolonged use of COX inhibitors can result in a variety of negative side effects, such as possible digestive and liver problems. Some COX inhibitors have recently been pulled from the market due to an increased risk of heart complications."
