Red fruit (Pandanus conoideus Lam) oil stimulates nitric oxide production and reduces oxidative stress in endothelial cells

2018

Abstract Red fruit oil (RFO) is used in traditional medicine for the treatment of a number of diseases. However, evidence for the biological effects and action mechanisms is still lacking. In the present study, we show for the first time that RFO stimulated the phosphorylation of the endothelial nitric oxide synthase (eNOS) and enhanced the NO production in human endothelial cells. In isolated mouse aorta, RFO induced a vasodilation, with a significant effect evident at a concentration as low as 1:100,000 dilution. The RFO-induced vasodilation could be completely prevented by eNOS inhibition, indicating that RFO contains highly potent substances stimulating eNOS activity. In addition, RFO r…

Phosphorylation and activation of endothelial nitric oxide synthase by red fruit (Pandanus conoideus Lam) oil and its fractions

2020

Abstract: Ethnopharmacological relevance Red fruit (Pandanus conoideus Lam) oil (RFO) is utilized by inhabitants of the Papua Island to treat diseases such as infections, cancer, and cardiovascular disease, but the mechanism of action is unknown. Aim of the study We have recently shown that RFO stimulates nitric oxide (NO) production in endothelial cells. The present study was conducted to investigate the molecular mechanism of endothelial NO synthase (eNOS) activation by RFO. Materials and methods NO production by endothelial cells was determined with electron paramagnetic resonance. The vascular function of isolated mouse aorta was examined using a wire myograph system. Phosphorylation of…
