Design and synthesis of conformationally constrained, extended and reverse turn pseudopeptides as Grb2-SH2 domain antagonists
摘要:
A series of conformationally constrained and flexible pseudopeptide derivatives of the tripeptide pYVN were prepared as potential antagonists of interactions of phosphotyrosine peptides with the Grb2-SH2 domain. The conformation ally constrained compounds contained trans- and cis-cyclopropanes as replacements to enforce locally extended and reverse turn peptide conformations, respectively.

procedure for the synthesis of peptide alkyl thioesters by 9-fluorenylmethoxycarbonyl (Fmoc) solid-phasepeptidesynthesis was developed. The free C terminus of a fully protected peptide was coupled in solution with the free amino group of an amino thioester. This furnished the fully protected peptidethioester, which was globally deprotected to afford the desired unprotected peptidethioester. The method
