Exendin-4 (5-39) amide (trifluoroacetate salt)

Exendin-4 (5-39) amide is a 34-amino acid synthetic peptide corresponding to residues 5-39 of exendin-4 (48-86) amide (Cay-11096) and an antagonist of the glucagon-like peptide 1 (GLP-1) receptor (IC50 = 0.3 nM) that has roles in synaptic transmission. It decreases GLP-1-induced increases in intracellular cAMP levels in CHO/pancGLPR cells. Exendin-4 (5-39) amide (10 and 100 nM) increases extracellular glutamate reuptake in primary rat hippocampal astrocytes. In vivo, exendin-4 (5-39) amide increases excitatory amino acid transporter 2 (EAAT2) protein levels and decreases the field excitatory postsynaptic potential decay time in the rat dentate gyrus when administered intracerebroventricularly.Synonyms: Exenatide Amide.
