CAS :Produit contrôlé6alpha-Fluoro-17,21-Dihydroxy-16alpha-Methylpregna-4,9(11)-Diene-3,20-Dione 21-Acetate is a synthetic angiostatic agent that inhibits the angiogenic process by affecting the growth of new blood vessels. It has been shown to inhibit proteolytic activity and to have an inhibitory effect on tumour necrosis factor-α (TNF-α) induced activation of endothelial cells and their proliferation. 6alpha-Fluoro-17,21-Dihydroxy-16alpha-Methylpregna-4,9(11)-Diene 3,20 Dione 21 Acetate also inhibits the growth of fetal bovine aortic endothelial cells in culture. The drug was also found to significantly reduce the monolayer cell viability after uptake by endothelial cells.Formule :C24H31FO5Degré de pureté :Min. 95%Masse moléculaire :418.5 g/mol1-(2',3'-Difluorophenyl)-2-nitroethene
CAS :1-(2',3'-Difluorophenyl)-2-nitroethene (1,2-DFNE) is a speciality chemical that is used as an intermediate for the synthesis of a wide variety of organic compounds. It has been found to be a useful scaffold for the synthesis of complex compounds and can also be used as a building block for the synthesis of fine chemicals, research chemicals, and versatile building blocks. 1,2-DFNE is soluble in many organic solvents and can be handled without special precautions. This reagent is a high quality compound with purity greater than 99%.Formule :C8H5F2NO2Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :185.13 g/molDL-Ethionine
CAS :DL-Ethionine is a compound that is formed when the amino acid methionine is converted to ethionine. It has been shown to induce the formation of acid in the liver and pancreas, which can lead to pancreatitis. Experimental models have shown that DL-ethionine causes liver injury by inhibiting tissue repair mechanisms, such as the polymerase chain reaction. This inhibition prevents DNA synthesis, leading to cell death. The mechanism of DL-ethionine induced toxicity is currently being investigated.Formule :C6H13NO2SCouleur et forme :PowderMasse moléculaire :163.24 g/mol
