Brilliant Blue is an organic compound classified as a blue triarylmethane dye. It is coal tar derivative food dye; used as the di-NH4 or di-Na salts. Coloring agent. Brilliant Blue FCF, has been used in foods in the US since 1929. This color adds a distinctive, bright blue hue to beverages, beverage powders, dairy products, baked goods, dessert powders, confections, condiments, icings, syrups, jams, jellies, marmalades, liqueurs, extracts, dairy fats and oil, meat, seafood, snacks, dry mixes and seasonings, fruit preparations, convenient food, and flavors. Both the diammonium and disodium salts of FD&C Blue No. 1 are used. The disodium salt is used in foods, while the diammonium salt has limited usage in drugs and cosmetics.

Doconexent (Docosahexaenoic acid, DHA) is an omega-3 fatty acid that is a primary structural component of the human brain, cerebral cortex, skin, and retina. DHA is widely used as a food supplement, and is beleived to support healthy brain development in young childred, prevent cardiovascular disease and cognitive decline during Alzheimer's disease. Most of these claims, however, were not supported by clinical trials. DHA spray is used as a tanner.

CTI-01 (ethyl pyruvate) is an investigational anti-inflammatory agent for the treatment of critical inflammatory conditions. CTI-01 was developed by Critical Therapeutics as a stable prodrug of pyruvate, a potent antioxidant, and a free radical scavenger. The drug showed an anti-inflammatory and tissue protection activity in animal models of pancreatitis, ischemia-reperfusion injury, sepsis, renal injury, and endotoxemia. CTI-01 was investigated in phase 2 clinical trials on patients undergoing cardiac surgery with cardiopulmonary bypass, but despite positive results in animal models, administration of EP does not appear to confer any benefit to cardiac surgical patients undergoing cardiopulmonary bypass. Besides clinical applications, ethyl pyruvate is long used as an additive to pharmaceutical preparations and foods, including candy, beverages, and baked goods. It is generally recognized as safe by the FDA.

Ethyl maleate is supposed to be a toxic agent. Its administration induced acute aflatoxicosis in goats. Ethyl maleate is also used as a cross-linking agent for the synthesis of polymers.

Ethyl cysteinate is derivative of semi-essential proteinogenic amino acid Cysteine. Ethyl cysteinate is widely used in food additive, cosmetic, pharmaceutical area. Ethyl cysteinate is membrane-permeable, readily enters peripheral tissues and the brain, and increases intracellular pools of cysteine in these tissues via a membrane-associated carboxylesterase. The increased availability of cysteine directly alters the redox status of cells and enhances glutathione production. The enhanced biovailability of L-cysteine and L-glutathione would also promote the direct formation of the S-nitrosothiols, L-S-nitrosocysteine and L-S-nitrosoglutathione and the overall S-nitrosylation status of functional proteins in cells.

Benzyldimethyl(2-(2-((4-(1,1,3,3-Tetramethylbutyl)-O-Tolyl)Oxy)Ethoxy)Ethyl)Ammonium colloquially known as Methylbenzethonium Chloride has been used in the study stem cell death-inducing small molecules as well as anti-leishmanial activity. It is a component of the pharmaceutical preparation 'Leshctan' antibacterial ointment in Isreal.
