Lidocaine hydrochloride (Lignocaine hydrochloride) is a local anesthetic and cardiac depressant used as an antiarrhythmic agent. Its actions are more intense and its effects more prolonged than those of PROCAINE but its duration of action is shorter than that of BUPIVACAINE or PRILOCAINE.

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.

Procaine (Vitamin H3) is a local anesthetic of the ester type that has a slow onset and a short duration of action. It is mainly used for infiltration anesthesia, peripheral nerve block, and spinal block.

TBHQ (tert-Butylhydroquinone) is an antioxidant that induces an antioxidant response through the redox-sensitive transcription factor Nrf2.

Folic acid (Vitamin B9) is a vitamin B9 that is essential for the synthesis of DNA/RNA and for the production and maintenance of new cells. Folic acid deficiency can lead to anemia, neural tube closure defects, tumors, aging, and other diseases.

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.

N-Nitrosodiethylamine (NDEA) is a potent hepatocarcinogenic dialkylnitrosoamine primarily found in water, tobacco smoke, cheddar cheese, cured and fried meals, and many alcoholic beverages. NDEA is responsible for changes in nuclear enzymes related to DNA repair/replication and induces various tumors in all animal species, targeting mainly the liver, nasal cavity, trachea, lung, and esophagus.

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