FPR Agonist 43 (10-5-107 nM) is actively potent in the cAMP assay in FPR2/ALX over-expressing CHO cells[1].
FPR Agonist 43 is also active in the GTPγ binding assay (IC50=207±51 nM)[1].
FPR1 is the preferred receptor for FPR Agonist 43 in in both human neutrophils and possibly also in mouse cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
