Work from Prof. Martin Paterson's group has been published in a leading journal of the American Chemical Society, Biochemistry (2014, 53, 787).  The work, in collaboration with Dundee Medical School, is a theoretical study detailing how the metformin anti-diabetes drug interacts with copper to determine its biomolecular mode of action.  This work will help to understand this important class of drugs, and aid in the design of new and better ones.
