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.

D&C Yellow No. 6 is an excipient (pharmacologically inactive substance). D&C Yellow No. 6 is a color additive. It has been approved for use in food, drugs, and cosmetics. D&C Yellow No. 6 is chemically manufactured by diazotizing 4-aminobenzenesulfonic acid using hydrochloric acid and sodium nitrite or sulfuric acid and sodium nitrite. The diazo compound is coupled with 6-hydroxy-2-naphthalene-sulfonic acid. The dye is isolated as the sodium salt and dried. The trisodium salt of 3-hydroxy-4-[(4-sulfophenyl)azo]-2,7-naphthalenedisulfonic acid which may be blended with the principal color is prepared in the same manner except the diazo benzenesulfonic acid is coupled with 3-hydroxy-2,7-naphthalenedisulfonic acid.

There is no information related to the biological and pharmacological application of levulinic acid. But is known, that levulinic acid was recognized by the US Department of Energy as one of the top biobased platform chemicals of the future. It is a versatile building block with a clear value proposition in chemicals. Levulinic acid can successfully address many performance-related issues attributed to petroleum-based chemicals and materials.

Hydroxymethanesulfinic acid is an organic acid. Sodium salt of hydroxymethanesulfinic acid (rongalite) is widely used in organic synthesis. It can be used as a reducing agent for elemental selenium and tellurium, diselenides, α‐halo ketones, and aromatic aldehydes; yields symmetrical sulfones with primary halides and with Michael acceptors.

Capric acid (decanoic acid) is a medium-chain fatty acid found in saturated fats (cow butter, and plant oils like coconut oil). Capric acid is a major constituent of the MCT ketogenic diet, providing about 40% of the medium chain fat within the diet. The acid is discussed to have positive effect on seizure control through direct AMPA receptor inhibition and on mitochondrial diseases through the binding to PPARgamma. It readily crosses the blood-brain barrier, probably by a combination of diffusion and saturable carrier-mediated transport via a medium-chain fatty acid transporter.
