Fragment-based lead discovery constructs drug leads from small molecular fragments. In theory, this is a highly efficient method for drug discovery, and the technique has become enormously popular in the past few years. In this review, I describe how a variety of approaches in fragment-based lead discovery — including NMR, X-ray crystallography, mass spectrometry, functional screening, and in silico screening — have produced drug leads. Although the examples show that the technique can reliably generate potent molecules, there is still much work to be done to maintain the efficiency of molecules’ binding affinities as fragments are linked, expanded, and otherwise improved.
