BioAssay: AID 239119

Displacement of L-[3H]glutamate from N-methyl-D-aspartate glutamate receptor in rat brain synaptic membranes

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. ..more

Title: Analogues of the neuroprotective tripeptide Gly-Pro-Glu (GPE): synthesis and structure-activity relationships.

Abstract: 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.
