Submit ReviewDiphenyleneiodonium chloride
Description: GPR3 agonist; also inhibits NOS and NADPH oxidases
Alternative Names: DPI
Chemical Name: [1,1'-Biphenyl]-2,2'-diyliodonium chloride
Purity: ≥99% (HPLC)
Biological Activity for Diphenyleneiodonium chloride
Diphenyleneiodonium chloride is a GPR3 agonist (EC50 = 1 μM); activates adenylate cyclase through GPR3 but not GPR6 or GPR12. Also induces Ca2+ mobilization and β-arrestin receptor internalization. Binds strongly to flavoproteins; inhibits several enzymes, including NO synthase, NADPH oxidases and NADPH cytochrome P450 oxidoreductase. Also inhibits platelet aggregation.
