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.
Alx40-4C trifluoroacetate is a chemokine receptor (CXCR4) inhibitor, which inhibits the binding of sdf-1 to CXCR4.Alx40-4ctrifluoroacetate was also an APJ receptor antagonist with an IC50 value of 2.9 M.
