PMX 205 acetate(514814-49-4 free base) 是补体 C5a 受体 (C5aR; CD88) 的拮抗剂。

PMX-53 is a Mas-related gene 2 (MrgX2) agonist and C5aR(CD88) antagonist. PMX-53 reduces atherosclerotic lesions in a mouse model of atherosclerosis, inhibits lung metastasis in a mouse breast cancer model, inhibits C5a-induced hypernociception in rats.

PMX-205 is a cyclic hexapeptide that acts as a potent antagonist of C5a receptor (C5aR; IC50= 31 nM).1It is orally active and blocks inflammatory signaling and symptoms in animal models of colitis and allergic asthma.2,3PMX-205 is also brain penetrant and reduces neuroinflammation and neurodegeneration in an animal model of Alzheimer's disease.4 1.March, D.R., Proctor, L.M., Stoermer, M.J., et al.Potent cyclic antagonists of the complement C5a receptor on human polymorphonuclear leukocytes.
