    Product Description

    MMK1 is an agonist of formyl peptide receptor 2 (FPR2), which was previously known as formyl peptide receptor-like 1 (FPRL1).1 MMK1 induces calcium flux in CHO cells expressing human FPR2 and Gα16 (EC50 = <2 nM) but not in CHO cells expressing Gα16 alone or in combination with FPR1 (EC50s = >10,000 nM for both). It induces chemotaxis of isolated human peripheral blood monocytes and neutrophils in a concentration-dependent manner.2 MMK1 (10 µM) increases production of the proinflammatory cytokines IL-1β and IL-6 in isolated human monocytes. Intracerebroventricular administration of MMK1 (100 pmol/mouse) increases the percentage of time spent in the open arms of the elevated plus maze in mice, indicating anxiolytic-like activity.3

    WARNING This product is not for human or veterinary use.
