Inhibition of protein–protein interactions using designed molecules

Author affiliations


Although many cellular processes depend upon enzymatic reactions, proteinprotein interactions (PPIs) mediate a large number of important regulatory pathways and thus play a central role in disease development. In order to understand and selectively inhibit cellular signalling pathways, there is a pressing need for small molecules that target PPIs, particularly in the context of pharmaceutical development. This tutorial review will introduce the relevance of PPIs to chemical biology and highlight the key challenges in designing inhibitors. Some of the successes using conventional approaches to the identification of small-molecule PPI inhibitors will be highlighted, and also the reasons why these approaches have not always proven successful. Several general approaches tailored to particular protein topologies are emerging for the design of scaffolds that inhibit PPIs—these will form the major content of this review. Finally a summary of the challenges to be faced in developing inhibitors of PPIs into drug leads and how these challenges may differ from those encountered with enzyme-like targets will be given.
