Pterostillbene: Benefits Of This Potent Antioxidant

Pterostilbene (trans-3,5-dimethoxy-4-hydroxytoluene) is a naturally derived compound found primarily in blueberries and Pterocarpus marsupium (PM) heartwood. The volume of regular pterostilbene consumption alters according to dietary fruit absorption, and it has been concluded that pterostilbene content per blueberry ranges from 99 ng to 520 ng/gram depending on the variety of berry ingested.

Substantial evidence suggests that pterostilbene may have numerous preventive and therapeutic properties in a vast range of human diseases that include neurological, cardiovascular, metabolic, and hematologic diseases. Additional interests of pterostilbene should be listed in preclinical analyses, in which pterostilbene was explicated to be a dominant anticancer agent in diverse malignancies.

Pterostilbene is structurally alike to resveratrol, an aggregate observed in red wine that has analogous antioxidant, anti-inflammatory, and anticarcinogenic characteristics; nonetheless, pterostilbene displays enhanced bioavailability due to the appearance of two methoxy combinations which create it to manifest heightened lipophilic and oral consumption.


  • Developing standards of obesity and inadequate nutrition are influential grantors to breast cancer occurring in women. Several types of research have revealed that blueberry infusion and pterostilbene restrain breast cancer in vitroand in vivo. Pterostilbene practice of breast cancer cells has additionally been given to remodel cellular oxidative motion that may perform an indispensable role in pterostilbene-mediated cell loss.

  • Supplementary examinations were administered to assess the influence of blueberry vulnerability upon in vitro representation of PTEN and antioxidant exercise in nontumorigenic breast cells, and outcomes exposed that cells handled with blueberry serum dispensed more important PTEN but the comparable antioxidant potential to examine cells. The verdicts prove that breast cells are initial points of blueberry-derived arbitrators, which control the strength to adjust developmental mammogenesis.

  • OESOPHAGUS: Oesophageal cancer has a poor prognosis with low rates of disease survival. Oxidative damage from smoking, alcohol, and gastroesophageal reflux disease (GERD) increases the risk of oesophageal cancer, which some suggest may be mitigated through the use of antioxidant agents.

In a study administered by Stoner and associates, the scholars assessed the data that a blueberry diet persuades anticarcinogenic, anti-inflammatory, and antioxidant consequences in N-nitroso-methyl-benzylamine (NMBA) reviewed rats. NMBA is an established carcinogen that induces tumorigenesis in the rat esophagus in a multistep fashion that is analogous to the oesophageal carcinogenesis in humans.

The scholars discovered that rats administered with NMBA for five weeks, accompanied by a blueberry diet for a whole of 35 weeks, had improved antioxidant motion, conquered tumorigenesis, and reduced expression of interleukin- (IL-) 5 and growth-related oncogene (GRO/KC), two seals of infection.


Pterostilbene is a stilbenoid chemically related to resveratrol. It relates to the organization of phytoalexins, factors generated by plants to fight diseases like Palmitoylethanolamide (PEA) at this link. Based on animal subjects it is conceived to exhibit anti-cancer, anti-hypercholesterolemia, anti-hypertriglyceridemia properties, as well as the strength to battle off and modify cognitive deterioration. It is assumed that the aggregate also has anti-diabetic characteristics.
