GLPG-0974

GLPG-0974 is a potent FFA2 (free fatty acid receptor 2) antagonist (IC50 = 9 nM). Displays selectivity for FFA2 over FFA3. GLPG-0974 inhibits acetate-induced migration of isolated human neutrophils in buffer or plasma (IC50s = 27 and 43 nM, respectively), as well as acetate-induced expression of CD11b activation-specific epitope on neutrophils in isolated human whole blood (IC50 = 438 nM).
