NADPH oxidase

Apocynin is a NADPH oxidase inhibitor

Diphenyleneiodonium chloride has been shown to be a potent irreversible inhibitor of NOS2 (iNOS) from macrophages and NOS3 (eNOS) from endothelial cells.

ML171 (2-Acetylphenothiazine;2-APT) is a potent and selective NADPH oxidase 1 (Nox1) inhibitor that blocks Nox1-dependent ROS generation, with an IC50 of 0.25 μM in HEK293-Nox1 confirmatory assay.

GKT137831 is a first in class inhibitor targeting NOX1 and NOX4 enzymes.

APX-115 (Ewha-18278) is a potent, orally active pan NADPH oxidase (Nox) inhibitor with Ki values of 1.08 μM, 0.57 μM, and 0.63 μM for Nox1, Nox2 and Nox4, respectively. APX-115 effectively prevents kidney injury.

GLX351322 is an inhibitor of NADPH oxidase 4 (Nox4), and inhibits hydrogen peroxide production from NOX4-overexpressing cells with an IC50 of 5 μM.

GSK2795039 is a NADPH oxidase 2 (NOX2) inhibitor with a mean pIC50 of 6 in different cell-free assays. GSK2795039 inhibits reactive oxygen species (ROS) production and NADPH consumption. GSK2795039 reduces apoptosis.

APX-115 free base (Ewha-18278 free base) is a potent, orally active pan NADPH oxidase (Nox) inhibitor with Ki values of 1.08 μM, 0.57 μM, and 0.63 μM for Nox1, Nox2 and Nox4, respectively.
