PMX 53 is a dual C5aR (CD88) antagonist and Mas-related gene 2 (MrgX2) agonist. It stimulates MrgX2-mediated mast cell degranulation, and 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.
