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.
ELA-32(human) TFA is a potent, high affinityapelinreceptoragonist (IC50=0.27 nM; Kd=0.51 nM). ELA-32(human) TFA exhibits no binding GPR15 and GPR25. ELA-32(human) TFA activates the PI3K AKT pathway and promotes self-renewal of hESCs via cell-cycle progression and protein translation. ELA-32(human) TFA also potentiates the TGFβ pathway, priming hESCs toward the endoderm lineage. ELA-32(human) TFA stimulates angiogenesis in HUVEC cells.
ELA-11(human) TFA is a high affinityapelinreceptoragonist (Ki=14 nM). ELA-11(human) TFA is a bioactive fragment of ELA-32. ELA-11(human) TFA inhibits forskolin-induced cAMP production and stimulates β-arrestin recruitment in vitro.
