CAS :<p>Cefradine impurity F is a hydrolysis product of cefradine, which is an antibiotic. It is catalysed by β-lactamase enzymes and undergoes nucleophilic attack on the carbon atom adjacent to the carbonyl group. Cefradine impurity F has been shown to be effective against enterobacter, which is a type of bacteria that can cause urinary tract infections. The uptake of cefradine impurity F into bacteria can occur through passive diffusion or active transport mechanisms. This drug was also found to be hydrolyzed by buffers such as phosphate and acetate in vitro, but not by other substances such as EDTA and citrate. Cefradine impurity F has been shown to be hydrolyzed in vivo, with the most likely mechanism being spontaneous hydrolysis.</p>Formule :C5H6O2SDegré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :130.17 g/mol(3b,9b,10a)-3-Hydroxy-pregna-5,7-dien-20-one

CAS :<p>1,3-Dimethylthiourea (DMU) is a chemical compound that has been shown to have antioxidant properties. DMU is an inhibitor of the enzyme aconitase, which catalyzes the second step in the Krebs cycle and is involved in energy metabolism. DMU inhibits the activity of other enzymes such as xanthine oxidase and nitric oxide synthase, which are responsible for the production of reactive oxygen species (ROS). DMU also shows pro-apoptotic properties by inducing activation of a pro-apoptotic protein called p53. DMU has been shown to be an effective treatment for eye disorders such as glaucoma and retinal degeneration when used together with low doses of corticosteroids. It has also been shown to protect against myocardial infarction and provide cardioprotection following reperfusion injury.</p>Formule :C3H8N2SDegré de pureté :Min. 95%Masse moléculaire :104.18 g/mol5α-Pregnan-20β-Ol-3-one

CAS :<p>2-Chloro-2',4'-difluoroacetophenone (2,4-DFAP) is an asymmetric synthesis of urea nitrogen. It has been shown to be a broad-spectrum antimicrobial, with activity against a number of fungi and bacteria. The molecular modelling of 2,4-DFAP has revealed that it has intramolecular hydrogen bonds and is a supramolecular enantiomer. Additionally, the transport properties have been studied and found to have chloride ions in the molecule. This may be responsible for its anti-fungal effects as well as its ability to inhibit the growth of cryptococcus neoformans.</p>Formule :C8H5ClF2ODegré de pureté :Min. 95%Masse moléculaire :190.57 g/molN-Acetyl-L-leucyl-L-leucyl-L-methioninal
