Although the human body has a balance between the oxidation promoting substance and the oxidation inhibiting substance, due to various factors, if such a balance state is lost and it is inclined to promote oxidation, oxidative stress is induced in the living body. Reactive oxygen species (ROS), which is a direct cause of oxidative stress, are chemically unstable and highly reactive, and can easily react with various biomaterials such as DNA, protein, lipid and carbohydrate. Attack, causing irreversible damage to cells and tissues, or mutation and cytotoxicity.

The deleterious ROS as described above is generally caused by superoxide dismutase, catalase, glutathione peroxidase, glutamine reductase, vitamin C, vitamin E, uric acid, bilirubin (bilirubin) is removed by the action of antioxidant system. However, when oxidative stress occurs, unremoved ROS causes various pathological changes, leading to cellular damage and pathological disease. In fact, it has been confirmed that oxidative stress is increased in many clinical diseases. Various studies on new antioxidants have been made to reduce such oxidative stress.

The macrophages respond to pathogens in the body and induce inflammatory factors such as tumor necrotic factor-α, TNF-α, interleukin-6 (IL-6) and interleukin-1β (IL-1β) (NO) and prostaglandin (prostaglandin E2, PGE2) were synthesized by synthesizing inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) . Physiologically, NO plays a variety of roles such as removing bacteria and tumors, regulating blood pressure, or mediating neurotransmission. However, when the inflammatory reaction occurs, the expression of iNOS is increased in related cells, and a large amount of NO is produced. Excessively produced NO causes tissue damage, gene mutation, nerve damage, etc., And promote the inflammatory response.
