FPR1, FPR2/ALX[1]

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]. Cell Viability Assay[1] Cell Line: Chinese hamster ovary (CHO) over-expressing human FPR2/ALX receptors Concentration: 10-5, 10-3, 0.1, 10, 1000, 105, 107 nM Incubation Time: Result: Actively potent in the cAMP assay in FPR2/ALX over-expressing CHO cells (IC50 =11.6±1.9 nM).
