Diphenyleneiodonium chloride (DPI)

Diphenyleneiodonium chloride (DPI) is an inhibitor of NADPH oxidase and also a potent, irreversible, and time-, temperature-dependent iNOS/eNOS inhibitor. Diphenyleneiodonium chloride (DPI) also functions as a TRPA1 activator and selectively inhibits intracellular reactive oxygen species (ROS).

S6656New

VAS2870

VAS2870 is a pan-NADPH oxidase (NOX) inhibitor.

S0777New

APX-115 free base

APX-115 free base (Ewha-18278 free base) is a potent, orally active inhibitor of pan NADPH oxidase (pan-Nox) with Ki of 1.08 μM, 0.57 μM, and 0.63 μM for Nox1, Nox2 and Nox4, respectively. APX-115 free base (Ewha-18278 free base) significantly suppresses the expression of inflammatory molecules including MCP-1/CCL2, IL-6, and TNFα in the diabetic kidney.

S2425

Apocynin

Apocynin (Acetovanillone) is a selective NADPH-oxidase inhibitor with IC50 of 10 μM.

S8974New

GSK2795039

GSK2795039 is an inhibitor of NADPH oxidase 2 (NOX2) with pIC50 of 6.57 for NOX2-mediated activation of HRP/Amplex Red. GSK2795039 inhibits reactive oxygen species (ROS) production, NADPH consumption and reduces apoptosis.

S0178New

GLX351322

GLX351322 is a NADPH oxidase 4 (NOX4) inhibitor. GLX351322 inhibits hydrogen peroxide production from tetracycline inducible NOX4-overexpressing cells with IC50 of 5 μM.

S2348

Rotenone (Barbasco)

Rotenone (Barbasco, Dactinol, Paraderil, Rotenon, Rotocide) is a botanical insecticide that is an inhibitor of mitochondrial electron transport. Rotenone inhibits NADH/DB oxidoreductase and NADH oxidase with IC50 of 28.8 nM and 5.1 nM, respectively. Rotenone induces apoptosis through enhancing mitochondrial reactive oxygen species production.

S7171

Setanaxib (GKT137831)

GKT137831 is a potent, dual NADPH oxidase NOX1/NOX4 inhibitor with Ki of 110 nM and 140 nM, respectivelyl; ~10-fold selectivity towards NOX1, 4 and 5 over NOX2, does not inhibit XO or scavange ROS/RNS. GKT137831 partly inhibits ferroptosis.

S5304

2-Acetylphenothiazine (ML171)

2-Acetylphenothiazine (ML171, 2-APT) is a potent and selective inhibitor of NADPH-oxidase with IC50s of 0.25 μM, 5 μM, 3μM, 5 μM and 5.5 μM for NOX1, NOX2, NOX3, NOX4 and xanthine oxidase, respectively.
