Fórmula:C15H14N2OPureza:Min. 95%Peso molecular:238.28 g/mol4-Hydroxy-17b-estradiol
CAS:Produto Controlado4-Hydroxy-17β-estradiol (4-OHE2) is a reactive metabolite of 17β-estradiol that binds to DNA and has been shown to have carcinogenic potential. The catechol-o-methyltransferase enzyme catalyzes the conversion of 4-OHE2 to 4-hydroxycatechol, which can then be further methylated by estrogen sulfotransferase or sulfatase to estrone and estrone sulfate. It has been shown that 4-OHE2 may be a potential biomarker for breast cancer. Experimental studies have shown that 4-OHE2 may act as an antioxidant in cancer tissues, but its activity has not been demonstrated in normal tissues. In order to demonstrate the ability of 4-OHE2 as an antioxidant, its activity was tested in vitro using human breast cancer cells (MDA MB 231). Results showed that 4-OHE2 decreased oxidative stress levels in these cells,Fórmula:C18H24O3Pureza:Min. 95%Cor e Forma:SolidPeso molecular:288.38 g/mol4-Amino-3-bromoisoquinoline

CAS:2-(2-Aminoethoxy)ethanol (2-AE) is a natural compound that has been synthesized from ethanol and 2-aminoethanol. It has been shown to react with sodium carbonate to form stable complexes that are resistant to hydrolysis by amines. The stability of the complex is attributed to the formation of an intermolecular hydrogen bond between the hydroxyl group on the 2-AE molecule and the carboxylate group on the sodium carbonate molecule. 2-AE reacts with benzalkonium chloride, a quaternary ammonium salt, in water vapor to produce an alcohol and a fatty acid, which is then hydrolyzed by glycol ethers into glycolates. This mechanism is similar to that of other reactions involving quaternary ammonium salts, such as those in fatty acids or glycol ethers.
