3,4,5-Trimethoxybenzoic acid (Gallic acid trimethyl ether) are potent antioxidants and inhibitor of cytokine production. It can ameliorate chronic stress-induced various behavioral and biochemical alterations in mice. It also exerts hepatoprotective effects in CCl4-induced rats, specifically by modulating oxidative-nitrosative stress and inflammation.

DL-Mevalonolactone, a human endogenous metabolite, is the δ-lactone form of mevalonate, a precursor of the mevalonate pathway. It reduces mitochondrial membrane potential (∆Ψm), Ca2+ retention and NAD(P)H levels in the brain, and also induces mitochondrial swelling.DL-Mevalonolactone induces inflammation and oxidative stress, and reduces mitochondrial membrane potential.

L-Methionine sulfoxide (H-Met(O)-OH) is a metabolite of Methionine that modulates oxidative stress and purinergic signaling parameters, while inducing M1 classical macrophage polarization.

Methionine sulfoxide, an oxidation product of methionine formed through interaction with reactive oxygen species, serves as a biomarker for oxidative stress in vivo.

Alginic acid (Snow acid algin G) is a natural polysaccharide extracted from brown seaweeds with anti-anaphylactic and anti-inflammatory activities. Alginic acid inhibits histamine release and can be used in the food industry.

Arecoline hydrobromide (Arecoline HBr) is a muscarinic acetylcholine receptor agonist.

Paeoniflorin (Peoniflorin) is a herbal constituent extracted from the root of Paeonia albiflora Pall.

L-Theanine is a relaxing and nondietary amino acid found pretty much exclusively in teas from Camellia sinensis and is known to promote relaxation without sedation.

Matrine (Vegard), an alkaloid isolated from the Sophora genus, acts as a kappa opioid receptor agonist.

Sinapinic Acid (Synapoic acid) protects the rat liver from CCl4-induced inflammation, most likely by acting as a free radical scavenger and modulator of NF-κB p65 activation and proinflammatory cytokine expression. Sinapic acid with antioxidant role protects cardiac cells and its functions from I R induced oxidative stress. Sinapic acid is a potentially useful agent for the protection against liver fibrosis and cirrhosis. Sinapic acid prevents the alterations in the levels of lipids and lipoproteins by virtue of its anti-lipidaemic effect in isoproterenol induced myocardial infarcted rats. Sinapic acid ameliorates hyperglycemia through PLC-PKC signals to enhance the glucose utilization in diabetic rats.

1. Oxyresveratro can inhibit tyrosinase activity. 2. Oxyresveratro is useful to trauma models, as toxicity to glia could be beneficial by inhibiting reactive gliosis. 3. Oxyresveratrol (trans-Oxyresveratrol) has antioxidant activity, can reduce neuronal oxidative damage and protect hepatocytes against oxidative stress and mitochondrial dysfunction, which may be associated with activation of Nrf2.

Uric acid sodium, scavengers of oxygen radicals, is a potent and common antioxidant that helps maintain stable blood pressure and resist oxidative stress. Uric acid sodium, which removes reactive oxygen species (ROS) such as singlet oxygen and peroxynitrite, has an inhibitory effect on lipid peroxidation and is associated with the pathogenesis of gout joint disease and the formation of calcium oxalate stones.

1,4-D-Gulonolactone (D-Gulonic acid γ-lactone) (also known as reduced ascorbic acid, RAA) is the substrate of the enzyme L-gulono-1,4-lactone oxidoreductase (EC 1.1.3.8), which catalyzes the last step of the biosynthesis of L-ascorbic acid (vitamin C) in plants and animals. The enzyme L-Gulono-1,4-lactone oxidase is missing in scurvy-prone, vitamin C-deficient animals, such as humans. 1,4-D-Gulonolactone is present in human blood and has been used as one of the markers to compare changes in exercise-induced oxidative stress.

geraniol provides a potent protective effect against cardiac dysfunction induced by diabetes. This ameliorative effect could be attributed to its suppression of oxidative stress.

DL-Homocysteine thiolactone hydrochloride (DL-Homocysteinethiolactone hydrochloride) is a cysteine derivative that binds to and induces conformational changes in various plasma proteins, slowing coagulation and inducing oxidative stress. It decreases left ventricular systolic blood pressure and cardiac force and induces seizures in vivo.

Methyl jasmonate ((-)-Methyl jasmonate) is a hormone involved in plant signaling, inducing oxidative stress and accumulation of secondary metabolites in plant cells and organ cultures, and regulating the biosynthesis of other plant hormones. Methyl jasmonate induces plant defense responses against Andean lupin insects. Methyl jasmonate has anti-inflammatory activity.

Zingerone (Vanillylacetone) is a nontoxic methoxyphenol isolated from Zingiber officinale, with potent anti-inflammatory, antidiabetic, antidiarrhoeic, antilipolytic, antispasmodic, and anti-tumor properties. Zingerone (Gingerone) alleviates oxidative stress and inflammation, down-regulates NF-κB mediated signaling pathways, acts as an anti-mitotic agent, and inhibits the growth of neuroblastoma cells.

Arecoline is a natural alkaloid derived from areca nut in the palm family and is a potent nicotine and partial agonist of muscarinic acetylcholine receptors. Arecoline has anti-anxiety and anti-parasitic activity, can induce oxidative stress and can be used to study Alzheimer's disease and Alzheimer's disease.
