Abstract
Fragment-based lead discovery complements high-throughput screening and computer-aided drug design for the discovery of small-molecule inhibitors of protein-protein interactions. Fragments are molecules with molecular masses ca 280 Da or smaller, and are generally screened using structural or biophysical approaches. Several methods of fragment-based screening are feasible for any soluble protein that can be expressed and purified; specific techniques also have size limitations and/or require multiple milligrams of protein. This chapter describes some of the most common fragment-discovery methods, including surface plasmon resonance, nuclear magnetic resonance, differential scanning fluorimetry, and X-ray crystallography.
