Elabela (19-32)

This compound is a potent and selective apelin receptor (APJ) agonist, derived from the bioactive fragment ELA-32. It demonstrates high affinity (Ki = 0.93 nM), activates Gαi1 and β-arrestin-2 pathways in vitro, and has been shown to lower arterial pressure in rat models, confirming its in vivo activity for cardiovascular research.
