| Description |
MMK1 is a potent and selective human formyl peptide receptor like-1 (FPRL-1/FPR2) agonist with EC50s of <2 nM and >10000 nM for FPRL-1 and FPR1, respectively. MMK1 is a potent chemotactic and calcium-mobilizing agonist. MMK-1 potently activated phagocytic leukocytes and could enhance Pertussis Toxin (HY-112779)-sensitive production by human monocytes of proinflammatory cytokines IL-1b and IL-6. MMK1 exerts anxiolytic-like activity[1][2][3][4].

MMK-1 induces calcium mobilization in human FPRL1-transfected HEK 293 (FPRL1/293) cells with a 50% effective concentration (EC50) at 2 nM[1]. MMK1 (1 μM; for 4 h) induces selective migration of FPR2-expressing RBL-2H3 cells[3].

| In Vivo |
MMK1 (10-1000 pmol; ICV; 20 min before the test) exerts an aniolytic-exerted an anxiolytic-like activity at a dose of 100 pmol/mouse[4]. Animal Model: Four-week-old male ddY mice[4] Dosage: 10, 100, 1000 pmol/mouse Administration: ICV; 20 min before the test Result: Exerted an aniolytic-exerted an anxiolytic-like activity at a dose of 100 pmol/mouse.
