an amine radical cation and an alpha-radical during enzyme catalysis, there is no direct, i.e. EPR, evidence for these species as they are formed. Amino nitrones have been designed which, upon radical formation would produce an intermediate that is a resonance structure of the corresponding nitroxyl radical, which should be observable by EPR spectroscopy. Syntheses of seven different amino nitrones
Embodiments of this invention include novel analogs of Glycyl-Prolyl-Glutamate (GPE) and compositions containing such analogs of GPE. Of these, certain analogs have modified proline residues. Other embodiments of this invention include uses of analogs of GPE to protect neural cells from degeneration and/or death in response to injury or disease. Disorders treatable with compounds and compositions of this invention include hypoxia/ischemia, toxic injury, and chronic neurodegenerative disorders including Parkinson's disease.

The synthesis of ten proline-modified analogues of the neuroprotective tripeptide GPE is described. Five of the analogues incorporate a proline residue with a hydrophobic group at C-2 and two further analogues have this side chain locked into a spirolactam ring system. The pyrrolidine ring was also modified by replacing the gamma-CH2 group with sulfur and/or incorporation of two methyl groups at C-5. (c) 2005 Elsevier Ltd. All rights reserved.
