Ac-P-G-A

Ac-Pro-Gly-Pro-OH is an endogenous degradation product of extracellular collagen and can be used as CXCR2 agonist. Ac-Pro-Gly-Pro-OH elicits bactericidal activity and inhibits lung inflammation, reducing immune cell apoptosis. Ac-Pro-Gly-Pro-OH enhances the production of type 1 cytokines (IFN-γ and IL-12) but inhibits the production of proinflammatory cytokines. Ac-Pro-Gly-Pro-OH has the potential for the research of sepsis.
