Synthesis of Casein-Related Peptides and Phosphopeptides. XVI. The Efficient Synthesis of the Casein-Related O-Phosphoseryl-Containing Peptide Ac-Glu-Ser(P)-Leu-Ser(P)-Ser(P)-Ser(P)-Glu-Glu-NHMe
Synthesis and neuroprotective activity of analogues of glycyl-l-prolyl-l-glutamic acid (GPE) modified at the α-carboxylic acid
摘要:
The synthesis of nine GPE* analogues, wherein the alpha-carboxylic acid group of glutamic acid has been modified, is described by coupling readily accessible N-benzyloxycarbonyl-glycyl-L-proline 2 with various analogues of glutamic acid. Pharmacological evaluation of the novel compounds was undertaken to further understand the role of the glutamate residue on the observed neuroprotective properties of the endogenous tripeptide GPE.

The title octapeptide was prepared by the synthesis of the fully protected tetra-Ser(PO3Ph2)-octapeptide by incorporation of Boc-Ser(PO3Ph2)-OH (Boc = t-butoxycarbonyl) in conventional Boc/solution phase peptidesynthesis, followed by the complete hydrogenolytic cleavage of the phenyl groups from the Ser(PO3Ph2)-octapeptide.
