Biochem/physiol Actions

MMK-1 is a potent and selective FPR2 (FPRL-1) agonist (Ca2+ flux EC50 <2 nM/FPR2 vs. >10 μM/FPR1 with respective HEK293 transfectants) and an effective calcium-mobilizing and chemotactic agent for human monocytes & neutrophils (1-1000 nM). MMK-1 increases pertussis toxin-sensitive inflammatory cytokines production in human monocyte cultures (50 ng/mL PT & 10 μM MMK-1), exerts anxiolytic-like activities in mice (100 pmol/mouse icv) and shows anti-alopecia efficacy in rats in vivo (100 mg/kg p.o. or 10 mg/kg i.p.).
Potent and selective FPR2 (FPRL-1) agonist and monocytes/neutrophils chemotactic agent with anti-alopecia efficacy in vivo.

Fu-Chao Liu et al.
Redox biology, 26, 101273-101273 (2019-07-22)
Neutrophil infiltration plays a significant pathological role in inflammatory diseases. NADPH oxidase type 2 (NOX2) is a respiratory burst oxidase that generates large amounts of superoxide anion (O2•-) and subsequent other reactive oxygen species (ROS). NOX2 is an emerging therapeutic

Previously, we found that an intraperitoneally administered chemotactic peptide, N-formyl-Met-Leu-Phe (fMLP), and MMK-1, a selective agonist of formyl peptide receptor-like 1 (FPRL1) receptor, the low affinity subtype of the fMLP receptor, prevented the alopecia in neonatal rats induced by the

Nature biotechnology, 16(13), 1334-1337 (1998-12-16)
We describe a procedure for isolating agonists for mammalian G protein-coupled receptors of unknown function. Human formyl peptide receptor like-1 (FPRL-1) receptor, originally identified as an orphan G protein-coupled receptor related to the formyl peptide receptor (FPR1), was expressed in
Regina Tavano et al.
Nanobiomedicine, 3, 2-2 (2016-01-01)
We tested whether amorphous SiO2-NPs and formylpeptide receptor (FPRs) agonists synergistically activate human monocytes and neutrophil polymorphonuclear granulocytes (PMNs). Peptide ligands specifically binding to FPR1 (f-MLP) and to FPR2 (MMK-1, WKYMVM and WKYMVm) human isoforms did not modify the association
J Y Hu et al.
Journal of leukocyte biology, 70(1), 155-161 (2001-07-04)
Human phagocytic leukocytes express the seven-transmembrane G-protein-coupled receptors formyl peptide receptor (FPR) and FPR-like 1 (FPRL1). MMK-1, a synthetic peptide derived from a random peptide library, is reported to induce calcium mobilization specifically in human FPRL1 gene-transfected cells. However, its
