Abstract

Cyclic phosphopeptides were prepared using ring-closing metathesis followed by phosphorylation. These cyclic phosphopeptides were designed to interact with the SH2 domain of Grb2, which is a signal transduction protein of importance as a target for antiproliferative drug development. Binding of these peptides to the Grb2 SH2 domain was evaluated by a surface plasmon resonance assay. High affinity binding to the Grb2 SH2 domain was maintained upon macrocyclization, thus indicating that this method can be used to assemble high affinity cyclic phosphopeptides that interfere with signal transduction cascades.
