Gpe analogs

The invention relates to GPE analogs, particularly GPE analogs capable of inducing an equivalent physiological effect to GPE within a patient. Such GPE analogs include peptides where the Gly of Gly-Pro-Glu is replaced by any of Ala, Ser, Thr, or Pro; where the Pro of Gly-Pro-Glu is replaced by any of Ala, Ser, Thr, or Gly; and where the Glu of Gly-Pro-Glu is replaced by any of Asn, Asp, or Gln. The GPE analogs of the invention have application in any method of therapy or porphylaxis in which GPE has application. These applications include the treatment of acute brain injury and neurodegenerative disease, including but not limited to injury or disease in the CNS. The GPE analogs will normally be administered as part of a pharmaceutical composition or preparation.
