H-GLN-ARG-PRO-ARG-LEU-SER-HIS-LYS-GLY-PRO-MET-PRO-ALA-OH Usage And Synthesis

Uses

(Ala13)-Apelin-13 is a potent apelin receptors (APJ) antagonist. (Ala13)-Apelin-13 inhibits gastric motility through vagal cholinergic pathway[1].

Biological Activity

(Ala13)-Apelin-13 corresponds to Apelin-13 with a Phe-to-Ala substitution at the C-terminus (F13A) and functions as an antagonist against apelin-dependent APJ functions both in cultures and in animal studies in vivo.

in vivo

(Ala13)-Apelin-13 (1-300 pmol/60 nl; microinjected into the DVC) decreases gastric tone and motility in a dose-dependent manner in rats[1].

Animal Model:250-300 g, Sprague-Dawley rats[1]
Dosage:1-300 pmol/60 nl
Administration:Microinjected into the DVC (dorsal vagal complex (DVC)
Result:Decreased gastric tone and motility in a dose-dependent manner with D50?≈?27 pmol for both antrum and corpus.
