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.
(Modifications: Phe-1 = N-terminal Ac, X-2 = Orn, X-4 = D-Cha, Lactam bridge: Orn-2 to Arg-6 )
