CAS:Naphthalene is a chemical that is used for wastewater treatment and as a pesticide. It is also used in the manufacturing of polymers, resins, and plastics. Naphthalene has antimicrobial properties due to its hydrophobic effect. Naphthalene's antimicrobial activity is based on its ability to react with the skeleton of bacterial cells and disrupt the integrity of their outer membrane. Naphthalene also interacts with proteins and DNA, causing cell death. The molecular mechanisms of naphthalene's antibacterial activity are not well understood but have been studied using Hl-60 cells, which are immortalized human monocytic leukemia cells. This study showed that naphthalene affects the cell cycle by inhibiting protein synthesis in bacteria through binding to ribosomes or by disrupting the dna replication process.

Discontinued productTocopherols
CAS:Tocopherols are fat-soluble vitamins that belong to the family of tocopherols and tocotrienols. Tocopherols have a number of biochemical properties and antioxidant properties. These properties make them important for maintaining energy metabolism in cells, preventing oxidation of other molecules, and protecting the body from damage by reactive oxygen species. Tocopherols are found in a variety of biological sources such as plants, vegetable oils, nuts, grains, fruits and vegetables. The most common form is alpha-tocopherol (a-T). Other forms include gamma-tocopherol (g-T), delta-tocopherol (d-T), beta-tocopherol (b-T), and alpha-tocotrienol (a-TT).

Discontinued product(±)-3-Methyl-2-oxovaleric acid
CAS:(±)-3-Methyl-2-oxovaleric acid is a fatty acid that is found in the mitochondria of liver cells and other tissues. It is an intermediate in the citric acid cycle and can be converted into acetyl-CoA, which is used for energy production. (±)-3-Methyl-2-oxovaleric acid has been shown to cause necrotic cell death when it binds to the mitochondrial membrane potential and causes a loss of ATP production. This results in a lack of energy for the cell, leading to cell death. (±)-3-Methyl-2-oxovaleric acid has also been shown to inhibit protein synthesis by decreasing uptake and increasing creatine kinase activity. This inhibition leads to decreased body formation and tissue culture growth in vitro.
