The design, synthesis, and evaluation of dipeptide analogues as ligands for the pp60(c-src) SH2 domain are described. The critical binding interactions between Ac-Tyr-Glu-N(n-C5H11)(2) (2) and the protein are established and form the basis for our structure-based drug design efforts. The effects of changes in both the C-terminal (11-27) and N-terminal (51-69) portions of the dipeptide are explored. Analogues with reduced overall charge (92-95) are also investigated. We demonstrate the feasibility of pairing structurally diverse subunits in a modest dipeptide framework with the goal of increasing the druglike attributes without sacrificing binding affinity.
