Recognized as a heat shock protein inhibitor, Quercetin can significantly reduce exosome release in TII models by downregulating Hsp70 or Hsp90.

Trimethylamine N-oxide (TMAO) is a colorless amine oxide produced from choline, betaine, and carnitine via intestinal microbial metabolism that accumulates in tissues of marine animals and prevents the protein-damaging effects of urea.Trimethylamine N-oxide induces inflammation through activation of ROS NLRP3 inflammasomes, which can induce fibroblast differentiation and cardiac fibrosis.

Acetylcysteine (NAC) is an N-acetyl derivative of cysteine, a ROS inhibitor and mucolytic agent. Acetylcysteine induces apoptosis, can be used to reduce mucus thickness, and has anti-influenza viral activity.

Fusarochromanone (FC-101) is a mycotoxin produced by Fusarium marcescens with potent antiangiogenic, anticancer and antimalarial activities. Fusarochromanone induces cell death in COS7 and HEK293 cells through activation of the JNK pathway.

2-Aminoethanethiol (Cysteamine) is a Cystine Depleting Agent. The mechanism of action of cysteamine is as a Cystine Disulfide Reduction.

Glucosamine (Chitosamine) is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Supplemental glucosamine may help to rebuild cartilage and treat arthritis.

Chlorogenic acid is a natural phenol found in honeysuckle. Chlorogenic acid has a wide range of biological activities including anti-inflammatory, antioxidant, antitumor, antimicrobial, and neuroprotective.

Glutathione oxidized (L(-)-Glutathione) is a GLUTATHIONE dimer formed by a disulfide bond between the cysteine sulfhydryl side chains during the course of being oxidized.

L-Ascorbic acid (Vitamin C) is a natural product that is a potent reducing agent and antioxidant. L-Ascorbic acid functions in fighting bacterial infections, in detoxifying reactions, and in the formation of collagen. L-Ascorbic acid is used in the treatment of scurvy.

S-Methyl-L-cysteine (S-Methylcysteine) is a natural product serving as a substrate in the methionine sulfoxide reductase A (MSRA) catalyzed antioxidant system, exhibiting neuroprotective, antioxidative, and anti-obesity properties.

Cysteamine hydrochloride (Thioethanolamine Hydrochloride) is an agent for the treatment of nephropathic cystinosis and an antioxidant.

Glabridin (KB-289522) may serve as an anti-inflammatory agent in diabetes-related vascular dysfunction, through regulating the synthesis and activity of iNOS under high-glucose levels; may possess a therapeutic effect on metabolic disorders( such as diabetes and hyperglycemia), by modulating glucose metabolism through AMPK in skeletal muscle cells. Glabridin may have potential as a chemopreventive agent against liver Y metastasis, by inhibiting the invasion of human HCC cells.

Squalene (AddaVax) is a natural organic compound originally obtained for commercial purposes primarily from shark liver oil, though there are botanical sources as well, including rice bran, wheat germ, and olives. All higher organisms produce squalene, including humans. Squalene is an intermediate product in the synthesis of cholesterol and shows several pharmacological properties such as hypolipidemic, hepatoprotective, cardioprotective, antioxidant, and antitoxicant activity.

Sodium dichloroacetate (BCA) , a specific inhibitor of pyruvate dehydrogenase kinase (PDK) with IC50 values of 183 and 80 μM for PDK2 and PDK4 respectively, has been shown to derepress a mitochondrial potassium-ion channel axis, trigger apoptosis in cancer cells, and inhibit tumor growth.

α-Vitamin E (Dexrabeprazole Sodium) is a naturally-occurring form of vitamin E, a fat-soluble vitamin with potent antioxidant properties.

Ellagic acid (Gallogen), a thickened tetracyclic natural product, is a potent CK2 inhibitor (IC50=40 nM; Ki=20 nM) with ATP-competitive properties. Ellagic acid is an antioxidant and also possesses antiproliferative activity.

1. Berberine (Umbellatine) is a potent oral hypoglycemic agent with beneficial effects on lipid metabolism. 2. Berberine may as a broad-spectrum anti-microbial medicine, a complementary therapeutic agent for HIV AIDS. 3. Berberine seems to act as an herbal antidepressant and a neuroprotector against neurodegenerative disorders. 4. Berberine is used in histology for staining heparin in mast cells. As a natural dye, berberine has a colour index of 7516. 5. Berberine reduces hepatic fat content in rats with nonalcoholic fatty liver disease; also prevents proliferation of hepatic stellate cells (HSCs), which are central for the development of fibrosis during liver injury. 6. Berberine can ameliorate proinflammatory cytokines-induced intestinal epithelial tight junction damage in vitro, and berberine may be one of the targeted therapeutic agents that can restore barrier function in intestinal disease states. 7. Berberine has antineoplastic effects, including breast cancer, leukemia, melanoma, epidermoid carcinoma, hepatoma, pancreatic cancer, oral carcinoma, tongue carcinoma, glioblastoma, prostate carcinoma and gastric carcinoma, etc.

Hesperidin (Cirantin) is a flavanone glycoside found in citrus fruits with antioxidant, anti-inflammatory, anti-carcinogenic, and antihypertensive and lipid-lowering activity.

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.

Urolithin C is a gut metabolite of ellagic acid. Urolithin C induces apoptosis in PC12 cells through a mitochondria-mediated pathway.

Gallic acid (Benzoic acid) is found in almost all plants. Plants known for their high gallic acid content include gallnuts,grapes,tea,hops and oak bark.

Rhein (NSC 38629) is an anthraquinone compound extracted from Polygonaceae Rheum Officinale with anti-inflammation and antitumor activities.

Echinacoside is a natural polyphenolic compound with various kinds of pharmacological activities, such as anti-inflammatory, antioxidative, hepatoprotective, neuroprotective, nitric oxide radical-scavenging and vasodilative ones.
