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.

Lycopene (ψ,ψ-Carotene) is a linear, unsaturated hydrocarbon carotenoid, the major red pigment in fruits such as tomatoes, pink grapefruit, apricots, red oranges, watermelon, rosehips, and guava. As a class, carotenoids are pigment compounds found in photosynthetic organisms (plants, algae, and some types of fungus), and are chemically characterized by a large polyene chain containing 35-40 carbon atoms; some carotenoid polyene chains are terminated by two 6-carbon rings. In animals, carotenoids such as lycopene may possess antioxidant properties which may retard aging and many degenerative diseases. As an essential nutrient, lycopene is required in the animal diet.

Phytic acid dodecasodium salt hydrate (myo-Inositol, hexakis(dihydrogen phosphate) dodecasodium salt hydrate) is a phosphorus storage compound of seeds and cereal grains. Phytic acid dodecasodium salt hydrate inhibits the enzymatic superoxide source xanthine oxidase with an IC50 of 6 mM and has antioxidative, neuroprotective, and anti-inflammatory effects.

Ethyl cinnamate has antifungal, and vasorelaxant effects. Ethyl cinnamate can lead to the damage of cell membrane system and metabolic disorder through inducing lipid peroxidation via initiating ROS overproduction. Ethyl cinnamate can inhibit the tonic contractions induced by high K+ and phenylephrine (PE) in a concentration-dependent manner, with respective IC50 values of 0.30 mM and 0.38 mM.
