WKYMVM is a N-formyl peptide receptor (FPR1) agonist.

WKYMVM-NH2 TFA, a potent agonist for N-formyl peptide receptor (FPR1) and FPRL1/2, activates key leukocyte effector functions including chemotaxis, complement receptor-3 mobilization, and NADPH oxidase activation, as documented in references [1] [2] [3].

WKYMVm is a selective FPR2 agonist with high affinity, which was identified through screening of a synthetic peptide library.

WKYMVM-NH2 is a hexapeptide that activates neutrophils and myeloid cells through the FPRL1 and FPRL2 receptors, with EC50 values of 2 nM for HL-60-FPRL1 cells and 80 nM for HL-60-FPRL2 cells. It also induces chemotaxis in HL-60 cells stably expressing FPRL2, with optimal migration observed at concentrations ranging from 10 to 50 nM. Additionally, WKYMVM-NH2 stimulates neutrophils to produce superoxide with an EC50 of 75 nM. It is applicable in research focused on inflammatory diseases.

WRW4-OH is a bioactive peptide that impedes the interaction of the FPRL1 agonist WKYMVm with its designated receptor. As a classical chemoattractant receptor prevalent in phagocytic cells of peripheral blood and brain, FPRL1's activation is integral to inflammatory responses within host defense mechanisms and is implicated in neurodegenerative disorders.

WRW4 TFA (878557-55-2 free base) is a specific formyl peptide receptor-like 1 (FPRL1) antagonist, inhibits WKYMVm binding to FPRL1 with an IC50 of 0.23 μM. WRW4 TFA(878557-55-2 free base) specifically inhibits the increase in intracellular calcium by the FPRL1 agonists MMK-1, amyloid beta42 (Abeta42) peptide, and F peptide.
