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.

Apremilast (CC-10004) (CC-10004) is a potent and orally active PDE4 (IC50=74 nM) with anti-inflammation activities.

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.

Lenalidomide (CC-5013) is an immunomodulator with oral activity. Lenalidomide is a ligand for the ubiquitin E3 ligase cereblon (CRBN), which selectively ubiquitinates and degrades two lymphoid transcription factors, IKZF1 and IKZF3, via the CRBN-CRL4 ubiquitin ligase, and is commonly used in the synthesis of PROTAC products.

Tempol (Tanol) is a superoxide scavenger. It has anti-inflammatory, neuroprotective and analgesic effects.

1. L-Arginine (L-Arg) exhibits anti-atherosclerotic effect. 2. L-Arginine and soy enriched diet are effective in prevention of osteoporosis associated with diabetes mellitus. 3. Exogenous L-Arginine could enhance neonate lymphocyte proliferation through an interleukin-2-independent pathway. 4. A combination of oral L-citrulline and L-Arginine effectively and rapidly augments NO-dependent responses at the acute stage.

Inosine pranobex (Delimmun) has a number of immunomodulatory effects, including inducing T-lymphocyte differentiation, augmenting macrophage and NK cell functions, and stimulating IL-2 production. Through these effects and others, isoprinosine shows antiviral activity and has applications against subacute sclerosing panencephalitis. It also restores depressed immune responses in Y patients after irradiation and reduces the incidence of infection in leukemia patients undergoing chemotherapy. It is most commonly used to treat the rare measles complication subacute sclerosing panencephalitis in conjunction with intrathecal interferon therapy.
