Alternative Name: WRW4

Biological Activity

Selective antagonist of formyl peptide receptor 2 (FPR2) signaling. Inhibits WKYMVm binding to FPR2 (IC50 = 0.23 μM) and inhibits intracellular calcium release induced by WKYMVm, MMK 1, amyloid β42, and F peptide. Also inhibits FPR2-mediated signaling in human neutrophils; blocks chemotactic migration and superoxide generation by amyloid β42 peptide.
