APJ receptor agonist 1, a potent biphenyl acid derivative, acts as an agonist (EC50 of 0.093 nM and 0.12 nM for human and rat APJ receptors, respectively) for the APJ receptor (APJ-R). It exhibits significant in vitro potency towards apelin-13, the endogenous peptidic ligand for the APJ receptor. APJ receptor agonist 1 holds promise for heart failure research.
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.
