New research may someday help natural-products chemists decrease by years the amount of time it takes for the development of certain types of medicinal drugs. The research involves computations of optical rotation angles on chiral — non-superimposable — molecules. Many chiral molecules are important for medical treatment for illnesses ranging from acid-reflux to cancer. The term “chiral” means that two mirror images of a molecule cannot be superimposed onto each other. In other words, some are “left-handed” and some are “right-handed.”
