extended peptide nature of most inhibitors. In the current study, a new binding motif was successfully developed by the incorporation of 3'-substituted tyrosine derivatives into a simplified nonphosphorylated cyclicpentapeptide scaffold (4), which resulted in high affinity Grb2-SH2 inhibitors without any phosphotyrosine or phosphotyrosine mimetics. The new L-amino acid analogues bearing an additional nitro
