affinity for the Grb2SH2domain, in the 10(-8)-10(-9) range of Kd values. These compounds behave as potent antagonists of the Grb2-Shc interaction. Our results highlight the importance of the doubly negative charge borne by the pY + 1 amino acid in accordance with the interactions observed in the complex crystallized between mAZ-pTyr-(alphaMe)pTyr-Asn-NH2 and the Grb2SH2domain. mAZ-pTyr-(alphaMe)pTyr-Asn-NH2
