Cétones

Cétones

Les cétones sont des composés organiques caractérisés par la présence d'un groupe carbonyle (C=O) lié à deux atomes de carbone. Ces composés sont très polyvalents et jouent un rôle crucial dans diverses réactions chimiques, notamment l'oxydation, la réduction et la condensation. Les cétones sont des intermédiaires essentiels dans la synthèse de produits pharmaceutiques, de parfums et de polymères. Chez CymitQuimica, nous proposons une large gamme de cétones de haute qualité pour soutenir vos applications de recherche et industrielles.

  • 3-Methylcyclopentanone

    CAS :
    <p>3-Methylcyclopentanone is a chiral compound that can be prepared by the asymmetric synthesis of 3-methylpentan-2-one. The chemical analyses of 3-methylcyclopentanone have been found to have a dry weight of 136.19 g/mol, with a molecular formula of C5H7O2. 3-Methylcyclopentanone can be identified by its hydrogen bonding interactions and hydroxyl group (-OH). The photoelectron spectrum shows the presence of an intramolecular hydrogen bond between the -OH group and one of the methyl groups. This intramolecular hydrogen bond is responsible for the high boiling point and low reactivity. This molecule has an a-type configuration, which gives it a higher mass analyzer peak at m/z = 166 than for other configurations, such as b or c.

  • 7-Hydroxy-4-cholesten-3-one-D7

    Produit contrôlé
    CAS :
    <p>7-Hydroxy-4-cholesten-3-one-D7 (7OHCD7) is a metabolite of the bile acid, cholic acid. It is generated by the action of cholesterol 7α hydroxylase on cholesterol in the liver. It is excreted in bile, which is then absorbed back into the body from the gut and used for energy metabolism. 7OHCD7 has been shown to be an inhibitor of histone deacetylases, which are enzymes that regulate gene transcription. This inhibition leads to increased transcriptional regulation and reduced inflammatory responses in bowel disease models. 7OHCD7 has also been shown to increase cholesterol levels and reduce inflammation in humans with metabolic syndrome.</p>

    CAS :
    <p>2-Bromo-1-cyclohexylethanone is an organic compound with a cyclohexane ring and two bromine atoms. It has been shown to be an inhibitor of the immunoproteasome, which is a protein complex that degrades proteins in the cell. This inhibition results in increased concentrations of hydrogen peroxide, which has antioxidant properties. 2-Bromo-1-cyclohexylethanone also has radical scavenging activity, which prevents the oxidation of other molecules by reactive oxygen species. This compound has shown medicinal values for autoimmune diseases, inflammatory diseases, and allergies. The flavonoids contained in 2-bromo-1-cyclohexylethanone are responsible for its antiallergic effects and its ability to inhibit histamine release from mast cells. 2-Bromo-1-cyclohexylethanone is stereoselective in inhibiting the immunoproteasome as it binds to only</p>

  • 5alpha-Androstan-3-one

    Produit contrôlé
    CAS :
    <p>5alpha-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 -</p>
