Ethyl gallate (gallic acid ethyl ester) obviously decreases cell proliferation in MDA-MB-231 and MCF-7 cells in a dose- and time-dependent manner, exhibits cytotoxicity in a dose-dependent manner. Ethyl gallate can inhibit the abilities of invasion of breast cancer in vitro by inhibiting the mRNA levels of MMP-9 MMP-2, phosphorylation of Akt and protein expression of NF-κB and inhibits hydrogen peroxide signaling, may represent an alternative class of vasopressors for use in septic shock. Also, Ethyl gallate suppresses proliferation and invasion in human breast cancer cells by modulating the PI3K Akt pathway, which may contribute to inhibiting their downstream targets such as NF-κB p-65, Bcl-2 Bax, and mRNA levels of MMP-2 and MMP-9 in breast cancer cells, could be used as potential antioxidants with safe therapeutic application in cancer chemotherapy.

Myrtenal is a natural monoterpene. It is found to attenuate diethylnitrosamine-induced hepatocellular carcinoma in rats by stabilizing intrinsic antioxidants and modulating apoptotic and anti-apoptotic cascades. Myrtenal also inhibits acetylcholinesterase

Kuromanin chloride (Chrysontemin chloride) is potent antioxidants and free radical scavengers, may act as modulators of gene regulation and signal transduction pathways.

Secoisolariciresinol diglucoside (LGM2605) was cytoprotective in an in vitro model of iron overload-induced redox-inflammatory damage. Secoisolariciresinol diglucoside (25 mg/kg b.w.) exerts the antihyperglycemic effect by preventing the liver from peroxidation damage through inhibition of ROS level mediated increased level of enzymatic and non-enzymatic antioxidants.

Cycloolivil (Isoolivil) is a natural polyphenolic compound found in olive trees that exhibits significant radical scavenging and antioxidant activities. It may prevent thrombotic complications associated with platelet hyperaggregability and serve as a foundational compound for further research.

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.

1. Homogentisic acid (2,5-dihydroxyphenylacetic acid) shows interesting antioxidant and antiradical activities, and protective effect against thermal-cholesterol degradation, comparable to those of well known antioxidants. 2. Homogentisic acid is the primary precursor of melanin synthesis in Vibrio cholerae, a Hyphomonas strain, and Shewanella colwelliana. 3. A derivative of homogentisic acid which inhibits Pfnek-1 with an IC(5) around 1.8 muM, this product is moderately active in vitro against a FcB1 P. falciparum strain (IC(5) = 12 muM).

Procyanidin (Standard) is the standard substance of Procyanidin, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Proanthocyanidins (PAs), also known as condensed tannins, are a class of polyphenols found in a variety of plants. They are very powerful antioxidants that remove harmful free oxygen radicals from cells.

1,2,4,6-Tetra-O-galloyl-β-D-glucose is an antioxidant found in eucalyptus. It exhibits significant superoxide dismutase (SOD)-like antioxidant activity (EC50: 1.55 μM). This compound inhibits tyrosinase (IC50: 0.59 mM) and hyaluronidase (IC50: 0.68 mM). It is applicable in food antioxidants, cosmetic anti-melanogenesis, and anti-allergic/anti-inflammatory research.

Danshenxinkun B has antioxIdant activity, it may have the potential of being used as natural antioxidants in foods and cosmetics.

Kaempferol-3-O-α±-D-arabinoside displays cytotoxic and high antioxidant activity.Kaempferol-3-O-arabinoside and kaempferol-3-O-glucoside can function as antioxidants in biological systems, particularly skin exposed to UV radiation by scavenging ROS, and protect cellular membrane against ROS; they can be applicable to new cosmeceuticals for antioxidant, antiaging, and antibacterial activity.

Andrographiside shows protective effects on hepatotoxicity induced in mice by carbon tetrachloride or tert-butylhydroperoxide (tBHP) intoxication, the effects could be due to its glucoside groups which may act as strong antioxidants.

(±)-ε-Viniferin, a racemate of ε-Viniferin, exhibits P450 inhibitory antioxidants, along with hepato-protective and antimicrobial activities. It also demonstrates antibacterial and antibiofilm activities against Gram-positive bacteria Streptococcus pneumoniae, with a minimum inhibitory concentration (MIC) of 20 μM [1].
