Chemical Name: 5-[(4-Nitrobenzoyl)oxy]-2-[(2-pyrimidinylthio)methyl]-4H-pyran-4-one
Biological ActivityML 221 is an apelin receptor (APJ) antagonist (IC50 values are 0.70 and 1.75 μM in a cAMP assay and β-arrestin assay, respectively). Displays >37-fold selectivity over the closely related angiotensin II type 1 (AT1) receptor. Exhibits no toxicity towards human hepatocytes at concentrations >50 μM.
