Uses
NADPH oxidase-IN-1 is an orally active NADPH oxidase (Nox) inhibitor, related with neuronal inflammation. NADPH oxidase-IN-1 can cross the blood-brain barrier (BBB), inhibits Nox2 and Nox4 with IC50s of 1.9 μM and 2.47 μM, respectively. NADPH oxidase-IN-1 suppresses pro-inflammatory cytokines production and LPS-mediated microglial migration, also has in vivo efficacy[1].
in vivo
NADPH oxidase-IN-1 (compound 11) (30 mg/kg; p.o.; daily for 4 wk) attenuates MPTP induced microglia activation and diminishes dopaminergic neuronal damage in Parkinson's disease (PD) mice model[1].
NADPH oxidase-IN-1 is safe in both male and female mice following IV injection (10-300 mg/kg; single dose) and oral gavage (10-1000 mg/kg; single dose), respectively[1].
