Described herein are improvements relating to IGF-1 analysis, adjustment and disease management of non-neurological and/or neurological conditions. More specifically, methods relating to the clinical application of cyclic glycine-proline (cGP) biomarker for prediction of risk and recovery of non-neurological and/or neurological conditions with IGF-1 dysfunction and the use of a cGP containing organic or plant based material such as concentrated extract of blackcurrant anthocyanins (BCA) for the treatment of same. The methods more accurately measure IGF-1 function in vivo indirectly using cGP and cGP/IGF-1 ratio along with a means to adjust cGP and cGP/IGF-1 ratio (and hence active IGF-1 concentration), and specific treatment methods for individuals with a lower or reduction of cGP level relative to a standard set of baseline data.

IGF-1 analysis, adjustment and disease management of non-neurological and/or neurological conditions

Embodiments of this invention provide methods for therapeutic use of cyclic G-2-Allyl Proline to treat cognitive disorders as well as manufacture of medicaments including tablets, capsules, injectable solutions that are useful for treatment of such conditions.

Cyclic Glycyl-2-Allyl Proline improves cognitive performance in impaired animals

Cyclic glycyl-2-allyl proline improves cognitive performance in impaired animals

This invention provides compounds, compositions and methods for treating a cognitive disorder or memory disorder in animals that result from aging or other neurodegenerative condition. In particular, compounds of this invention can stimulate neural cell growth, increased amounts of cells containing a key enzyme needed for production of the cholinergic neurotransmitter, and can improve memory and cognitive function in animals who have experienced a loss of memory or cognitive function.

Cognitive enhancement and cognitive therapy using glycyl-L-2-methylprolyl-L-glutamic acid

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 provide methods for thereapeutic use of cyclic G-2-Allyl Proline to treat disorders of dopaminergic neurons, including Parkinson's disease. Cyclic G-2Allyl P is neuroprotective and has utility as a therapeutic agent for treatment of diseases and other conditions characterised by degeneration and/or death of dopaminergic neurons and the adverse symptoms of such degeneration and/or death. Such symptoms include loss of cognition and motor function. Compounds are also useful for manufacture of medicaments including tablets, capsules and injectable solutions that are useful for treatment of such conditions.

Cyclic G-2Allylproline in treatment of Parkinson's disease

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

Embodiments of this invention include methods for increasing the amount of the enzyme tyrosine hydroxylase (TH) in the central nervous system (CNS) of mammals in need of an increase in TH. Methods include the use of the tripeptide, gly-pro-glu (GPE) to increase TH in the CNS. GPE can increase the amount of TH and/or decrease the loss of TH in conditions characterized by a loss of dopamine, such as Parkinson's disease and CNS injury. GPE may act to increase the expression of TH or by inhibiting a decrease in TH expression within the CNS or by inhibiting the loss of TH-containing neurons within the CNS. By increasing the amounts of TH in the CNS, GPE can increase the amount of the neurotransmitter, dopamine, in areas of the CNS responsible for adverse symptoms of neural injury or disease.

Regulation of tyrosine hydroxylase by GPE

A method for treatment or prophylaxis of a patient suffering from functional symptoms of Parkinson's disease, especially as a consequence of damage to dopaminergic neurons, by administering to the patient a neuroprotective amount of a peptide selected from the tripeptide gly-pro-glu (GPE) and analogs and mimetics thereof, preferably GPE. The GPE will usually be administered subsequent to the onset of Parkinson's disease but prior to the damage of said dopaminergic neurons.

Methods to improve neural outcome

This invention relates to methods of regulating the effect of tyrosine hydroxylase (TH). In particular it relates to increasing the effective amount of TH in the central nervous systems (CNS) for the purpose of increasing TH-mediated dopamine production in the treatment of conditions such as Parkinson's disease.

Regulation of tyrosine hydroxylase

This invention relates to the use of the tripeptide Gly-Pro-Glu (GPE) or analogs thereof for the treatment of conditions of the central nervous system (e.g. cerebral vasculitis) in which the amount of the neural enzymes nitric oxide synthetase (NOS) and/or glutamic acid decarboxylase (GAD) is reduced.

Regulation of neural enzymes

Disclosed herein is a method for protecting dopaminergic neurons of a mammal against death resulting from Parkinson's disease. The method comprises administering a neuroprotective amount of the tripeptide Gly-Pro-Glu.
