Niazirin
Based on 1 Customer Validation
Niazirin is an orally active antioxidant. Niazirin can be isolated from Moringa oleifera Lam. Niazirin reduces the production levels of ROS and MDA, while increasing the levels of superoxide dismutase SOD and glutathione peroxidase GPx. Niazirin also abolishes high glucose-induced PKCζ activation and inhibits Nox4 protein expression. Niazirin exhibits excellent free radical scavenging activity. Niazirin significantly inhibits high glucose-induced proliferation of vascular smooth muscle cells. Niazirin can be used in the research of diabetic atherosclerosis.

Niazirin (2-64 μM; 24 h) dose-dependently inhibits high glucose-induced abnormal proliferation of porcine aortic VSMCs, with no effect on VSMCs under normal glucose conditions[1].
Niazirin (5-25 μM; 24 h) significantly reduces high glucose-induced ROS production in porcine aortic VSMCs[1].
Niazirin (5-25 μM; 48 h) reverses high glucose-induced oxidant-antioxidant imbalance in porcine aortic VSMCs by reducing MDA production and increasing T-AOC, GPx, and SOD levels[1].
Niazirin (5-25 μM) inhibits high glucose-induced activation of the PKCζ/Nox4 pathway in porcine aortic VSMCs by reducing PKCζ Thr410 phosphorylation and Nox4 protein expression[1].
