Biological Activity for PMX 53

PMX 53 is a potent C5a receptor antagonist (IC₅₀ = 20 nM). Also MrgX2 agonist. Stimulates MrgX2-mediated mast cell degranulation. Also inhibits C5a-induced hypernociception in rats, inhibits lung metastasis in a mouse breast cancer model and reduces atherosclerotic lesions in a mouse model of atherosclerosis.

Negative Control also available.
