    We report first non-covalent and exclusively extracellular inhibitors of 14-3-3 protein-protein interactions identified by virtual screening. Optimization by crystal structure analysis and in vitro binding assays yielded compounds capable of disrupting the interaction of 14-3-3σ with aminopeptidase N in a cellular assay.
