WRW4 TFA, a specificformyl peptide receptor-like 1 (FPRL1)antagonist, inhibits WKYMVm binding to FPRL1 with anIC₅₀of 0.23 μM. WRW4 TFA specifically inhibits the increase in intracellular calcium by the FPRL1 agonists MMK-1, amyloid beta42 (Abeta42) peptide, and F peptide^[1].

WRW4 TFA inhibits Abeta42 peptide-induced superoxide generation and chemotactic migration of neutrophils, and also completely inhibits the internalization of Abeta42 peptide in human macrophages. WRW4 TFA specifically blocks ERK phosphorylation downstream of FPRL1 by WKYMVm^[1].
