5alpha-Androstan-3-one
CAS :Produit contrôlé5alpha-Androstan-3-one is a metabolic intermediate of testosterone. It is found in the urine of humans and other mammals, but at concentrations that are 10 to 100 times lower than those of testosterone. It is also found in some plants and fungi. 5alpha-Androstan-3-one can be synthesized from cholesterol, or it can be formed by the hydroxylation of testosterone in response to the action of cytochrome P450 enzymes. The synthesis of 5alpha-androstan-3-one from cholesterol requires a significant amount of energy, so it is not likely to be a major route for its production. In contrast, the conversion of testosterone to 5alpha-androstan-3-one is an important pathway for maintaining physiological levels of this metabolite. The activity of 5alpha-androstan-3-one has been shown to depend on its concentration in tissues and cells. At low concentrations (less than 10 nM) 5alpha -

CAS :1-(2-Furyl)-1,3-butanedione is an organic compound with the chemical formula CO. It is a diketone that acts as a metal chelate. The molecule has been shown to have antibacterial properties against gram-negative bacteria and also inhibits the growth of amyloid plaques in Alzheimer's disease. 1-(2-Furyl)-1,3-butanedione binds to the chlorine atom of a bacterial cell wall and prevents it from binding to the amine group on the surface of proteins, which are vital for protein synthesis. This leads to a decrease in bacterial growth. 1-(2-Furyl)-1,3-butanedione can be used as an alternative for chlorine gas in water purification processes because it reacts with HCl and converts it into less toxic hydrogen chloride.

Produit arrêté2-Amino-6-chloropyrimidin-4(3h)-one
CAS :2-Amino-6-chloropyrimidin-4(3H)-one (ACPP) is a betaine that has been shown to exhibit potent activity against clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA). It is a mesomeric molecule, which means that it can exist as two different tautomers. The frequency of the absorption bands in the FTIR spectra for ACPP are characteristic of the carbenes and ethanolamine tautomers. The presence of these tautomers may be due to stabilization from the nucleophilic character of the nitrogen atom in betaines. Betaines are also able to form polymersized chains by reacting with themselves or other molecules, such as ethanolamine.
