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. MMK1 potently activates phagocytic leukocytes and enhances Pertussis Toxin-sensitive production by human monocytes of proinflammatory cytokines IL-1b and IL-6. MMK1 exerts anxiolytic-like activity[1][2][3][4]. | [Biological Activity]
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.). | [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. |
