Description

[Pyr1]-Apelin-13 is a highly potent, selective endogenous apelin receptor (APJ) agonist.


P-Glu-Arg-Pro-Arg-Leu-Ser-His-Lys-Gly-Pro-Met-Pro-Phe is a thirteen-membered polypeptide consisting of p-Glu, Arg, Pro, Arg, Leu, Ser, His, Lys, Gly, Pro, Met, Pro and Phe residues joined in sequence. It has a role as an apoptosis inhibitor, a neuroprotective agent and a human metabolite. It is a tautomer of a [Pyr1]apelin-13(2+).

PYR-ARG-PRO-ARG-LEU-SER-HIS-LYS-GLY-PRO-MET-PRO-PHE-OH Use and Manufacturing

The apelin gene encodes a pre-proprotein that is processed to generate bioactive peptides consisting of 36, 17, or 13 amino acids: apelin-36 , apelin-17, and apelin-13 , respectively. Apelin-13 is an endogenous ligand of the APJ receptor, activating this G protein-coupled receptor with an EC50 value of 0.37 nM. (Glp1)-Apelin-13 is a pyroglutamylated form of apelin-13, in that the N-terminal glutamine residue is cyclized to pyroglutamic acid. Like apelin-13, this compound is a potent APJ receptor agonist (EC50 = 0.30 nM). (Glp1)-Apelin-13 is the major apelin isoform in the plasma of healthy human subjects. It can have vasoconstrictor and antipyretic effects in vitro and in vivo.
