Myricetin is an effective antioxidant in the treatment of obesity and obesity-related metabolic disorders. The objective of this study was to explore the regressive effect of myricetin on pre-existing hepatic steatosis induced by high-fat diet (HFD). C57BL/6 mice were fed either a standard diet or a HFD for 12 weeks and then half of the mice were treated with myricetin (0.12% in the diet, w/w) ...

The mechanisms underlying myricetin-induced cancer cell apoptosis remain to be elucidated. Certain previous studies have shown that myricetin induces apoptosis through the mitochondrial pathway. Apoptosis, however, can also be induced by other classical pathways, including endoplasmic reticulum (ER) stress and DNA double‑strand breaks (DSBs). The aim of the present study was to assess whether t...

Recently, we demonstrated that myricetin exhibits cytoprotective effects against H(2)O(2)-induced cell damage via its antioxidant properties. In the present study, myricetin was found to inhibit H(2)O(2)-induced apoptosis in Chinese hamster lung fibroblast (V79-4) cells, as shown by decreased apoptotic bodies, nuclear fragmentation, sub-G(1) cell population, and disruption of mitochondrial memb...

Myricetin, a naturally occurring flavonol, has been shown to inhibit the proliferation of human hepatoma HepG2 cells and to induce G2/M phase arrest. However, the underlying mechanisms of Myricetin activity have yet to be revealed. The aim of the present study was to clarify the molecular mechanisms of cell cycle arrest induced by myricetin in HepG2 cells. The MTT assay confirmed that exposure ...

flavonoids are wide range of phytochemical with various pharmacological effects including antioxidant, anti-inflammation, anti-platelet, anti-allergic, cytotoxicity, reduce risk for heart disease or cancer etc. these flavonoids inhibited various enzymes such as prostaglandin synthase, lypoxygenase, cyclooxygenase, and induced detoxifying enzyme systems such as glutathione s-transferase. flavono...

The aim of the present study was to compare the ability of the myricetin and quercetin to modulate the oxidative DNA damage induced by 2-amino-3, 8-dimethylimidazo [4,5-f] quinoxaline (8-MeIQx), 2-amino-3, 4, 8-trimethylimidazo [4, 5-f]-quinoxaline (4,8-diMeIQx) and 2-amino-1-methyl-6-phenyl-imidazo [4,5-b] pyridine (PhIP), in human hepatoma cells. DNA damage (strand breaks and oxidized purines...

Periodontitis is a common chronic inflammatory disease, which leads to alveolar bone resorption. Healthy and functional alveolar bone, which can support the teeth and enable their movement, is very important for orthodontic treatment. Myricetin inhibited osteoclastogenesis by suppressing the expression of some genes, signaling pathways, and cytokines. This study aimed to investigate the effects...

BACKGROUND Plant extracts are sources of valuable compounds with biological activity, especially for the anti-proliferative activity against pathogens or tumor cells. Myricetin is a flavonoid found in several plants that has been described as an inhibitor of Human immunodeficiency virus type 1 (HIV-1) through its action against the HIV reverse transcriptase, but myricetin derivatives have not b...

Bioguided fractionation of a leaves extract from Limoniastrum feei (Girard) Batt. (Plumbaginaceae) led to the isolation of seven polyphenolic constituents: gallic acid (1), myrciaphenone A (2), myricetin-3-O-beta-galactopyranoside (3-1), epigallocatechin gallate (3-2), myricetin 3-O-alpha-rhamnopyranoside (4), quercetin (5) and myricetin (6). Gallic acid was the most antioxidant compound in DPP...

The health beneficial effects of dietary polyphenols have been attributed to their intrinsic antioxidant activity, which depends on the structure of the compound and number of hydroxyl groups. In this study, the protective effects of pyrogallol, phloroglucinol, and myricetin on the yeast Saccharomyces cerevisiae were investigated. Pyrogallol and myricetin, which have a pyrogallol structure in t...
