Piceatannol (3,5,3',4'-tetrahydroxy- trans-stilbene), a resveratrol analogue, is a polyphenol present in the skins of grapes and in wine and other foods. The present study aimed to investigate for the first time the cardioprotective effects of piceatannol on vascular smooth muscle cells (VSMC). The

The intensity and duration of an inflammatory response depends on the balance of factors that favor perpetuation versus resolution. At sites of inflammation, neutrophils adherent to other cells or matrix components are exposed to tumor necrosis factor-alpha (TNFalpha). Although TNFalpha has been

Cross-linking of beta2 integrins caused diminished responses of neutrophils to priming agents like lipopolysaccharide or tumor necrosis factor-alpha: possible involvement of tyrosine kinase Syk.

Neutrophils up-regulate beta2 integrins like CD11b/CD18 in response to lipopolysaccharide (LPS). Up-regulation of beta2 integrins causes neutrophils to adhere to surfaces, and to release superoxide anion (O2-). When neutrophils are exposed to LPS plus plasma under conditions not favorable for

Piceatannol upregulates endothelial heme oxygenase-1 expression via novel protein kinase C and tyrosine kinase pathways.

Piceatannol is an anti-inflammatory and anti-proliferative plant-derived stilbene. Heme oxygenase-1 (HO-1) is a cytoprotective enzyme to activate by various phytochemicals. In this study, we examined the ability of piceatannol to upregulate HO-1 expression in endothelial cells. We found piceatannol

Effects of resveratrol, piceatannol, tri-acetoxystilbene, and genistein on the inflammatory response of human peripheral blood leukocytes.

Piceatannol (PIC), a natural analog of resveratrol (RES), is a phytochemical found in passion fruit seeds. To clarify the effects of PIC on obesity-induced inflammation in adipose tissue, we investigated the anti-inflammatory activity of PIC-related compounds (PIC, RES, and metabolites from PIC) in

Piceatannol is a phenolic stilbenoid and a metabolite of resveratrol which is found in red wine. Piceatannol (PIC) commonly exhibits anti-inflammatory, antiplatelet and antiproliferative activity. In the present study, the anti-allergic and anti-inflammatory mechanisms of PIC were investigated by

Effects of Piceatannol and Resveratrol on Sirtuins and Hepatic Inflammation in High-Fat Diet-Fed Mice.

Piceatannol (PIC) is a natural hydroxylated analog of resveratrol (RSV) and considered as a potential metabolic regulator. The purpose of this study was to compare the effects of PIC and RSV on parameters affecting inflammation, oxidative stress, and sirtuins (Sirt). Male C57BL/6J mice, 20 weeks

Piceatannol protects against cisplatin nephrotoxicity via activation of Nrf2/HO-1 pathway and hindering NF-κB inflammatory cascade.

This study investigates the molecular mechanisms of the nephroprotective effect of piceatannol (PIC) against cisplatin-induced nephrotoxicity in rats. PIC (10 mg/kg i.p.) was given for 7 days, starting 2 days before cisplatin single injection (7 mg/kg i.p.). Serum creatinine, blood urea nitrogen

Piceatannol attenuates lipopolysaccharide-induced NF-kappaB activation and NF-kappaB-related proinflammatory mediators in BV2 microglia.

Proinflammatory mediators, such as prostaglandin E(2) (PGE(2)), nitric oxide (NO), and proinflammatory cytokines [interlukin (IL)-1beta, IL-6, and tumor necrosis factor (TNF)-alpha] play pivotal roles in brain injuries. Anti-inflammatory responses are associated with significant downregulation of

The Cutibacterium acnes (also called Propionibacterium acnes, P. acnes)-induced proliferation and migration of keratinocytes contribute to acne vulgaris (AV), which is a common inflammatory skin disease that causes physical and psychological impairments. Piceatannol (3, 5, 3',

Differential effects of resveratrol and its natural analogs, piceatannol and 3,5,4'-trans-trimethoxystilbene, on anti-inflammatory heme oxigenase-1 expression in RAW264.7 macrophages.

Resveratrol (Res) and its two natural analogs that are also related to Res metabolism, piceatannol (Pic) and 3,5,4'-trans-trimethoxystilbene (TMS), were compared in their ability to suppress lipopolysaccharide (LPS)-induced production of proinflammatory tumor necrosis factor-α (TNF-α) and

Resveratrol analog piceatannol restores the palmitic acid-induced impairment of insulin signaling and production of endothelial nitric oxide via activation of anti-inflammatory and antioxidative heme oxygenase-1 in human endothelial cells.
