Tamarixetin (4'-O-Methyl Quercetin) is a natural flavonoid derivative of quercetin exhibiting multi-target biological activities including anti-inflammatory, antioxidant, antitumor, neuroprotective, and cardiovascular protective effects. Tamarixetin exerts its biological activity through multiple mechanisms such as direct radical scavenging, signaling pathway regulation, enzyme inhibition, and receptor binding.
Hyperoside (Hyperin) is a naturally occuring flavonoid compound which shows multiple bioactivities, including myocardial protection, anti-redox, and anti-inflammatory activities.
1. Herbacetin induces apoptosis in HepG2 cells, by ROS and PI3K/Akt pathway. 2. Herbacetin suppresses the HGF-induced motility of human breast cancer MDA-MB-231 cells by inhibiting c-Met and Akt phosphorylation.
1. Tiliroside (Tribuloside) shows anticarcinogenic activity. 2. Tiliroside shows hepatoprotective activity. 3. Tiliroside shows antioxidant and anti-inflammatory activity, can inhibit neuroinflammation in neurodegenerative disorders. 4. Tiliroside has anti-diabetic effect, are at least partially mediated through inhibitory effects on carbohydrate digestion and glucose uptake in the gastrointestinal tract. 5. Tiliroside and gnaphaliin are antioxidants against in vitro Cu(2+)-induced LDL oxidation in the same order of magnitude compared to that of the reference drug, probucol. 6. Tiliroside enhances fatty acid oxidation via the enhancement adiponectin signaling associated with the activation of both AMP-activated protein kinase and peroxisome proliferator-activated receptor α and ameliorates obesity-induced metabolic disorders.
Kaempferol (Robigenin) is a natural flavonoid and an inverse agonist of ERRα and ERRγ. Kaempferol has a wide range of antitumor, anti-inflammatory, antioxidant, antibacterial and antiviral activities.
Astragalin (Kaempferol 3-O-glucoside) is a biologically active natural flavonoid. It has a variety of pharmacological properties, including antioxidant, anti-inflammatory, anti-cancer, neuroprotective, and cardioprotective properties.
Wushanicaritin is a natural product isolated from the traditional Chinese medicine Epimedium plants, with antitumor effects and anti-inflammatory property.
Isorhamnetin (3-methylquercetin) is the methylated metabolite of quercetin. Quercetin is an important dietary flavonoid with in vitro antioxidant activity. Isorhamnetin prevents endothelial cell injuries from oxidized LDL via inhibition of lectin-like ox-LDL receptor-1 upregulation, interference of ox-LDL-mediated intracellular signaling pathway (p38MAPK activation, NF-kappaB nuclear translocation, eNOS expression) and the antioxidant activity of isorhamnetin. Isorhamnetin prevents endothelial dysfunction, superoxide production, and overexpression of p47phox induced by angiotensin II. Isorhamnetin appears to be a potent drug against esophageal cancer due to it's in vitro potential to not only inhibit proliferation but also induce apoptosis of Eca-109 cells.
1. Nicotiflorin (Kaempferol-3-O-Rutinoside) has potential therapeutic effects on cerebral ischemic illness. 2. Nicotiflorin has protective effects on reducing memory dysfunction, energy metabolism failure and oxidative stress in multi-infarct dementia model rats.
Tricetin is a flavonoid isolated from pomegranate.Tricetin is a potent competitive inhibitor of Keap1-Nrf2 protein-protein interaction (PPI) and protects Parkinson's disease patients from 6-OHDA-induced neurotoxicity by activating the Nrf2/HO-1 signaling pathway and blocking mitochondria-dependent apoptotic pathways.Tricetin Inhibits migration and expression of the indicator protease progerin-1 (PS-1) in nasopharyngeal carcinoma through the Akt/GSK-1β pathway.Tricetin inhibits endothelial inflammation induced by oxidized LDL mediated by Egr-1, and protects rat chondrocytes from IL-1β-induced inflammation and apoptosis.Tricetin is an inhibitor of endothelial inflammation induced by oxidized LDL mediated by Egr-1 and protects against IL-1β-induced inflammation and apoptosis.
Rutin (Quercetin 3-O-rutinoside), a flavonoid, has a variety of biological activities including antiallergic, anti-inflammatory, antiproliferative, and anticarcinogenic properties.
Gossypin has antidiabetic, antioxdiant, anticonvulsant, anti-allergic, antiinflammatory, antinociceptive, cytotoxic and antibacterial activities; it inhibits the NF-kappaB activation pathway, which may explain its role in the suppression of inflammation,
