3a-Hydroxy tibolone
CAS:Controlled ProductTibolone is a synthetic hormone that is used in the treatment of menopausal symptoms and breast cancer. Tibolone has been shown to be an effective treatment for menopausal symptoms, such as hot flashes and vaginal dryness, by providing relief from these symptoms. Tibolone has also been shown to have anti-cancer effects. This drug may be useful for treating breast cancer because it can inhibit the growth of cancer cells by binding to estrogen receptors and blocking estrogen-induced cell proliferation. Tibolone also stimulates angiogenesis, which is the formation of new blood vessels in order to provide nutrients and oxygen to growing tissue. It has been shown that this drug inhibits the synthesis of hepg2 cells in vitro, which are involved in the production of angiogenic factors. Tibolone may also have clinical relevance as a chemopreventive agent against prostate cancer.BR> Tibolone has also been shown to stimulate sulphatase activity in vitro, which may contribute to

Discontinued productL-Aspartic acid alpha-tert-butyl ester
CAS:L-Aspartic acid alpha-tert-butyl ester is a synthetic amino acid that can be used as a substrate for the synthesis of L-cysteine in the presence of selenomethionine. This compound is an auxotroph and cannot be synthesized by the body, so it must be obtained through diet or supplementation. It has been shown to have anti-cancer properties, which may be due to its role in regulating cell proliferation, apoptosis, and angiogenesis. L-Aspartic acid alpha-tert-butyl ester may also inhibit colon cancer cells by preventing them from recycling proteins. This compound was shown to inhibit HCT116 human colon cancer cells in both experimentally and computationally studies. Additionally, this molecule was seen to induce tumor regression in mice with colitis by inhibiting eukaryotic protein synthesis. This inhibition was found to be mediated through a trifluoromethyl group on the molecule's

Formula:C5H12N2OPurity:Min. 95%Molecular weight:116.16 g/mol(±)-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.

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.
