• PubMed Abstract: 
  

Protein-structure-based combinatorial chemistry has recently been used to discover several ligands containing non-peptide binding elements to the Src SH3 domain. The encoded library used has the form Cap-M1-M2-M3-PLPPLP, in which the Cap and Mi's are composed of a diverse set of organic monomers. The PLPPLP portion provided a structural bias directing the non-peptide fragment Cap-M1-M2-M3 to the SH3 specificity pocket. Fifteen ligands were selected from > 1.1 million distinct compounds. The structural basis for selection was unknown.
