KMN-80

KMN-80, a derivative of PGE1 (HY-B0131), is a selective and potent agonist of EP4 receptor with an IC50 and a Ki of 3 nM and 2.35 nM, respectively. KMN-80 is against EP3 receptor with an IC50 of 1.4 μM and >10 μM for all other prostanoid receptors[1]. KMN-80 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
