Analogues of the neuroprotective tripeptide Gly-Pro-Glu (GPE): synthesis and structure–activity relationships
摘要:
A series of GPE analogues, including modifications at the Pro and/or Glu residues, was prepared and evaluated for their NMDA binding and neuroprotective effects. Main results suggest that the pyrrolidine ring puckering of the Pro residue plays a key role in the biological responses, while the preference for cis or trans rotamers around the Gly-Pro peptide bond is not important.

Diesters of L-α-amino dicarboxylic acids were specifically hydrolysed by promise at their a carboxylic group while the corresponding D-enantiomers remained unchanged. This enabled easy obtention of sidechainbenzyl esters of L-α-amino dicarboxylic acids starting from both optically active and raceme dibenzyl ester derivatives.
