The design of effective inhibitors of protein–protein interactions is challenging. In a new study, thermal fluctuation of protein structure was simulated to identify small-molecule candidates that inhibit protein–protein interactions. The application of this technique to other protein–protein interactions might facilitate the replacement of biologic agents with orally available small-molecule drugs.
