eNOS activator-1
eNOS activator-1 is an orally active, blood-brain barrier permeable endothelial nitric oxide synthase (eNOS) activator. eNOS activator-1 upregulates eNOS mRNA expression, enhances endogenous NO biosynthesis, and activates the eNOS signaling pathway to maintain blood-brain barrier integrity. eNOS activator-1 upregulates the protein expression levels of PI3K, AKT, p-PI3K, and p-AKT. eNOS activator-1 reduces oxidative stress levels by decreasing lipid peroxidation and restoring antioxidant enzyme activities. eNOS activator-1 upregulates the expression of tight junction proteins ZO-1 and occludin, increases Cav-1 expression, and inhibits MMP-9-mediated blood-brain barrier disruption. eNOS activator-1 can be used in the research of ischemic stroke.

体外実験
eNOS activator-1 (1.8-60 μM; 24 h) shows no detectable cytotoxicity in primary rat neuronal cells at concentrations as high as 60 μM[1].
eNOS activator-1 (50 μg/mL; 18 h at 25 °C) demonstrates excellent predicted passive blood-brain barrier permeability in the in vitro PAMPA assay[1].
eNOS activator-1 (0.9-30 μM) exerts strong and consistent neuroprotective activity against oxygen-glucose deprivation/reperfusion injury in primary rat cortical neurons[1].
eNOS activator-1 (0.005 mM; 1-10 h) releases a stable, low concentration of NO over a 10 hour in vitro incubation[1].
eNOS activator-1 (compound 10) exerts an in vitro blood-brain barrier protective effect in primary rat neuronal OGD/R cultures that is fully dependent on eNOS activation, which regulates downstream Cav-1 and MMP-9 signaling[1].

体内実験
eNOS activator-1 (20-40 mg/kg; p.o.; single pretreatment 2 hours before MCAO then once daily; 6 consecutive days after surgery) exerts potent neuroprotective, anti-inflammatory, antioxidant, and BBB-preserving effects in the rat MCAO/R ischemic stroke model, reducing infarct volume to as low as 24.1% at the 40 mg/kg dose[1].
