1. Introduction of Pterostilbene

Pterostilbene is an antifungal active ingredient in blood products. It is a polyhydroxy stilbene compound and is a homologue of resveratrol. Its pharmacological action is similar to that of resveratrol. Antifungal activity (the antifungal activity is five times that of resveratrol).

Pterostilbene is a chemical component contained in Pterostilbene, but scientists have also discovered the existence of Pterostilbene in other plants, but it was named Pterostilbene because it was first discovered in Pterostilbene. Pterostilbene is a white or off-white powder crystal, which has rich medicinal value. It belongs to the antifungal active ingredient in the dried blood products, and has a certain effect on the treatment of cancer, hypertension and hyperlipidemia. Recently, researchers have mastered the industrial synthesis method of pterostilbene.

3. Function &Application of Pterostilbene

Pterostilbene is considered a powerful natural antioxidant mainly in:
①Reduce oxidative stress and reactive oxygen species, such as hydrogen peroxide H2O2 and superoxide anion O2;
②The expression of catalase in different cell lines increased, such as total glutathione, glutathione peroxidase, glutathione reductase, superoxide dismutase SOD and so on. The antioxidant effects of pterostilbene may work through multiple interrelated mechanisms. Pterostilbene can up-regulate the expression of manganese superoxide dismutase Mn-SOD in the mitochondrial matrix through the activation and expression of Bcl-2-related X protein, inhibit mitochondrial respiration and reduce the production of superoxide. Or act on low-density lipoprotein receptor-1, reduce the generation of reactive oxygen species, and down-regulate the expression of matrix metalloproteinases. Pterostilbene can also activate nuclear factor-related factor 2 (NF-E2-relatedfactor 2, Nrf2) to exert its antioxidant effect. For example, pterostilbene can activate Nrf2 and cause heme oxygenase-1 and glutathione reductase. It is highly expressed, which has the effect of anti-oxidation and anti-cancer, and its effect is stronger than that of resveratrol. When pterostilbene acts on pancreatic cancer β cells, it can activate Nrf2 in it, and increase the target genes such as heme oxygenase-1, carnitine acetyltransferase, SOD, glutathione oxidase and anti-apoptosis downstream of Nrf2. Expression of the apoptotic gene bcl-2 with dose- and time-dependent resistance
