Description: AC-264613 is the first agonist of the G-protein-coupled receptor (GPCR) protease activated receptor 2 (PAR2). AC-264613 suppresses interferon regulatory factor 5 and decreases interleukin-12p40 production by lipopolysaccharide-stimulated macrophages. AC-264613 activated PAR2 signaling in cellular proliferation assays, phosphatidylinositol hydrolysis assays, and Ca(2+) mobilization assays, with potencies ranging from 30 to 100 nM.
