Formyl Peptide Receptor (FPR) Inhibitor

LL-37 amide TFA is a selective agonist of formyl peptide receptor-like FPRL1, effectively inhibiting periodontal pathogens (ED₉₉=8.5-8.7 μg/mL). LL-37 amide TFA exerts its bactericidal effect by activating FPRL1-mediated immune cell chemotaxis and disrupting bacterial cell membrane integrity. It can also regulate inflammatory responses (inhibiting the release of factors such as TNF-α) and promote angiogenesis. Amidation modification reduces its sensitivity to serum inhibition and improves its stability. LL-37 amide TFA possesses key activities in bactericidal action, immunomodulation, and wound healing, and is mainly used in research on infection-related diseases such as periodontal disease and deep tissue injuries (pressure ulcers), and wound healing.

N-Formyl-MMYALF is a potent mitochondrial N-formyl peptide (mtFP) that has the activity of depleting calcium ions in the endoplasmic reticulum. N-Formyl-MMYALF can inhibit the FPR-1-mediated chemotactic response of polymorphonuclear leukocytes (PMNs) to bacterial peptides.

BVT173187 is a selective inhibitor of the neutrophil formyl peptide receptor FPR1, with activity that inhibits FPR1 activation. BVT173187 inhibits FPR1 agonist-induced activation in neutrophils, reduces adhesion molecule mobilization and superoxide anion production, and has inhibitory activity on FPR1 similar to that of earlier described peptide antagonists, but also has effects on C5aR and CXCR signaling.

Annexuzlimab is a humanised IgG1 monoclonal antibody which specifically binds to ANXA1 disrupting its interaction with formyl peptide receptors 1 and 2 (FPR1/2). Annexuzlimab arrests cell cycle progression with cancer cells accumulating in the G1 phase. Annexuzlimab targets secreted ANXA1, preventing FPR1/2 activation and reducing cancer progression. Annexuzlimab can be used for the research of triple negative breast cancer, pancreatic cancer and osteosarcoma.

WRW4-OH is a biological active peptide. (This peptide inhibits binding of one of formyl peptide receptor-like 1 (FPRL1) agonists WKYMVm to its specific receptor. FPRL1 is an important classical chemoattractant receptor that is expressed in phagocytic cells in the peripheral blood and brain. Activation of FPRL1 is closely related to inflammatory responses in the host defense mechanism and neurodegenerative disorders.)
