In this chapter, we have focused on the practical aspects fragment‐based discovery and provided some examples of its successful application. The methods are now firmly established in most pharmaceutical companies, particu- larly as the number of “fragment‐inspired” compounds entering clinical trials has increased [5]. Most of the examples that have been published to date have been of the “conventional” use of fragments, either linking, grow- ing, or merging. However, as the methods become increasingly integrated and adopted by medicinal chem- ists, other attributes of fragment‐based discovery are becoming apparent.
