APJ Receptor Agonist 4 is a potent, orally active apelin receptor (APJ) agonist, demonstrating an EC50 of 0.06 nM and a Ki of 0.07 nM. It exhibits excellent pharmacokinetic profiles in rodent heart failure (HF) models and has shown an acceptable safety profile in preclinical toxicology studies. This compound effectively improves cardiac function, making it valuable for research into HF disease.
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.
ML233 is a potent non-peptide apelin receptor agonist (EC50 = 3.7 μM) that exhibits more than 21-fold selectivity over the closely related angiotensin 1 receptor (AT1) (>79 μM) [1].
ELA-32(human) TFA is a potent, high affinityapelin receptoragonist (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.
