elabela

Potent apelin (APJ) receptor agonist (Ki = 0.93 nM). Bioactive fragment of ELA-32. Activates Gαi1 pathway and β-arrestin-2 recruitment. Reduces arterial pressure in rat hearts. Active in vivo.

Elabela(19-32) TFA, an effective fragment of ELABELA (ELA), selectively engages with the apelin receptor (APJ). This compound initiates G αi1 and β-arrestin-2 signaling, demonstrating EC50 values of 8.6 nM and 166 nM, respectively. It facilitates receptor internalization, lowers arterial pressure, and has a positive inotropic impact on cardiac function [1].
