Abstract
Protein-protein interactions (PPIs) are important to every cellular process, from signaling pathways to protein post-translational modifications, as well as many cellular machines for complex biological functions. These interactions make up the so-called interactomics of the organism, and aberrant PPIs are the cause of multiple diseases, including aggregation-related Alzheimer’s disease and many types of cancers. Therefore, modulating the protein-protein interactions was considered as the precise way for pharmacological interventions. In this chapter, we first briefly introduced the fragment-based drug discovery and summarized the current consideration for constructing the fragment library and commonly adopted fragment screening methods. In the second part, we first classified the PPIs into four categories based on the interaction pattern and size of interfaces. Then we reviewed recent progress of utilizing the fragment-based drug discovery approach to develop antagonists of various interesting PPIs and organized these case studies into a biological function-oriented way.
