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. In vivo, (±)-3-Methyl-2-oxovaleric acid causes primary sclerosing cholangitis, a disease characterized by inflammation of bile ducts that
