rac-Olodanrigan (rac-EMA401; EMA400) is a racemic mixture of the S-enantiomer (EMA401; HY-13106) and R-enantiomer (EMA402). rac-Olodanrigan is a potent and selective AT2 receptor antagonist with IC50s of 75.2 nM and 2918 nM for AT2R and AT1R, respectively. rac-Olodanrigan evokes dose-dependent relief of mechanical allodynia in the ipsilateral hind paws of rats with a chronic constriction injury (CCI) of the sciatic nerve[1].
