Proteins are modularly built from a limited set of approximately 1000 structural domains. The evolutionary relationship within a domain family suggests that the knowledge about a common fold structure can be exploited for the design of small molecule libraries in the development of inhibitors and ligands. This principle has been used for the synthesis of inhibitors for kinases sharing the same fold. It can also be applied for proteins which share the same fold architecture yet belong to different functional classes. Bestatin originally known as an aminopeptidase inhibitor was employed as guiding structure for the development of leukotriene A4 hydrolase inhibitors. A combinatorial approach helped to identify inhibitors for sulfotransferases which share structural similarity with nucleotide kinases using a kinase inhibitor core structure as guiding principle.
