NPPB

NPPB is a chloride channel blocker (IC50 = 80 nM) that has also been identified as a GPR35 agonist. It has been shown to activate the GPR35-Galphai/o and GPR35-Galpha16 pathways in HEK293 cells, inducing intracellular calcium mobilization. NPPB has protonophoric activity and has been used to uncouple mitochondrial ATP synthesis in phagocytes.Formal Name: 5-nitro-2-[(3-phenylpropyl)amino]-benzoic acid. CAS Number: 107254-86-4.
