General description

Pterostilbene (trans-3,5-dimethoxy-4-hydroxystilbene), an antioxidant is an analogue of resveratrol. It is present in blueberries, tree wood and some types of grapes.

Application

Pterostilbene has been used:
  • to investigate its anti-oxidative stress activities and the involvement of the nuclear factor (erythroid-derived 2)-like 2 (Nrf2)-antioxidant response element (ARE) signaling pathway
  • to determine its effects on transcriptional activation of estrogen receptor-α (ERα) in hormone resistant breast cancer cells)
  • to study its effects on the cytotoxicity of 2-chloroethyl ethyl sulphide (CEES) in human epidermoid carcinoma cells (A-431) through MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide)viability assay

Biochem/physiol Actions

Pterostilbene exhibits antineoplastic properties in some of the malignancies, hence it is considered as an active anticancer agent. It has the ability to stimulate apoptosis and block the viability of cell in estrogen-receptor positive and negative breast cancer cell lines.
Antioxidant, antiproliferative, apoptosis inducer, antihyperglycemic, antidiabetic.

Recent studies have implicated resveratrol and pterostilbene, a resveratrol derivative, in the protection against age-related diseases including Alzheimer's disease (AD). However, the mechanism for the favorable effects of resveratrol in the brain remains unclear and information about direct cross-comparisons between

The effects of resveratrol and pterostilbene (two structurally related stilbene compounds) on three human colon cancer cells were systematically compared. Cell viability tests indicated that IC(50) values of pterostilbene were 2-5-fold lower than those of resveratrol in all three cancer
