Embodiments of this invention include synthetic compounds (NRP analogs) of peptides termed neural regeneration peptides (NRPs). NRP analogs are made by substituting amino acids in the native peptide sequence, modifying amino acids chemically, by replacing amino acids with synthetic moieties, by stabilizing &#x3b2;-turns, acetylation of terminal glycine residues or by cyclization. NRP analogs can be used to treat a variety of conditions involving degeneration of neural cells, and includes treating disorders of the nervous system, including peripheral neuropathy, multiple sclerosis, diabetic peripheral neuropathy, neurotoxin-induced neurodegeneration, and amyotrophic lateral sclerosis.

Neural regeneration peptide consisting of a sequence comprised in the sequence of REGRRAAPGRAGG(SEQ ID NO:1).

Neural regeneration peptides and formulations thereof

Embodiments of this invention provide novel cyclic compounds structurally related to diketopiperazines and methods for their therapeutic use. Such compounds are neuroprotective and have utility as therapeutic agents for treatment of diseases, injuries and other conditions characterized by neuronal degeneration and/or death. Compounds are also useful for manufacture of medicaments useful for treatment of such conditions.

Neuroprotective bicyclic compounds and methods for their use

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.

Analogs of glycyl-prolyl-glutamate

The invention discloses a family of neuronal migration-inducing, proliferation-promoting and neurite outgrowth promoting factors, termed NRP compounds, and provides compositions and methods for the use of NRP compounds in the treatment of brain injury and neurodegenerative disease. NRP compounds induce neurons and neuroblasts to proliferate and migrate into areas of damage caused by acute brain injury or chronic neurodegenerative disease, such as stroke, trauma, nervous system infections, demyelinating diseases, dementias, and metabolic disorders. NRP compounds may be administered directly to a subject or to a subject's cells by a variety of means including orally, intraperitoneally, intravascularly, and directly into the nervous system of a patient.

Neural regeneration peptides and methods for their use in treatment of neural injury or degeneration

This invention provides analogs and peptidomimetics of glycyl-L-prolyl-L-glutamic acid (GPE). In particular, this invention relates to GPE analogs and peptidomimetics that are anti-apoptotic, anti-necrotic and have neuroprotective effects. These agents are useful in treating neurodegeneration and behavioural disorders caused by toxins, traumatic brain injury and autoimmune disorders of the brain, such as multiple sclerosis and in reducing seizures.

Effects of glycyl-2 methyl prolyl glutamate on neurodegeneration

The invention discloses a family of peptides termed NRP compounds or NRPs that can promote neuronal migration, neurite outgrowth, neuronal proliferation, neural differentiation and/or neuronal survival, and provides compositions and methods for the use of NRPs in the treatment of brain injury and neurodegenerative disease. NRP compounds can induce neurons and neuroblasts to proliferate and migrate into areas of damage caused by acute brain injury or chronic neurodegenerative disease, such as exposure to toxins, stroke, trauma, nervous system infections, demyelinating diseases, dementias, and metabolic disorders. NRP compounds may be administered directly to a subject or to a subject's cells by a variety of means including orally, intraperitoneally, intravascularly, and directly into the nervous system of a patient. NRP compounds can be formulated into pharmaceutically acceptable dose forms for therapeutic use. Methods for detecting neural regeneration, neural proliferation, neural differentiation, neurite outgrowth and neural survival can be used to develop other neurally active agents.
