small peptides with the sequence mAZ-pTyr-Xaa-Asn-NH(2), where Xaa denotes alpha-methylphosphotyrosine or its carboxylic mimetics, were synthesized as inhibitors of the Grb2SH2domain. Peptide 3 with (alpha-Me)pTyr as Xaa has the highest affinity for Grb2 (K(d) = 3 +/- 1 nM) and exhibits to date the best inhibitory activity (IC(50) = 11 +/- 1 nM) to displace PSpYVNVQN-Grb2 interaction in an ELISA test
