Gly-Pro-Glu
Based on 1 Customer Validation
Gly-Pro-Glu is a neuroactive peptide with a potent action on acetylcholine release. Gly-Pro-Glu is the N-terminal tripeptide of insulin-like growth factor-I. Gly-Pro-Glu inhibits glutamate binds to N-methyl-D-aspartate (NMDA) receptor with an IC50 value of 14.7 μM. Gly-Pro-Glu can be used for the research of neuroprotection .

Biological Activity
IC50: 14.7 μM (glutamate binds to NMDA receptor)[1]
Gly-Pro-Glu (0-100 μM) potentiates the potassium evoked release of both acetylcholine and dopamine, increases K+ evoked acetylcholine release even at concentrations of 0.1 nM and significantly enhances evoked dopamine release[1]. Gly-Pro-Glu (1-1000 μM) shows an inhibition of L-[3H]glutamate binding with an IC50 value of 14.7 μM[1].

Animal Model:Ovariectomized rats with Abeta25-35 injection[2]
-
Dosage:300 mg
-
Administration:Intraperitoneal injection; 300 mg per day; on day 0, 6 and 12
-
Result:Recovered Abeta25-35-induced the reduction of somatostatin (SRIF) content and SRIF receptor density, and reduced the inhibitory effect of SRIF on adenylyl cyclase activity.
