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.

  • 2-Bromo-1-cyclohexylethanone

    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>

    CAS :
    1-(2,3-Dihydroxypropyl)-3,7-dihydro-3,7-dimethyl-1H-purine-2,6-dione (theophylline) is a bronchodilator and anti-inflammatory agent. It is used to treat asthma and other respiratory conditions. Theophylline is structurally similar to caffeine and theobromine and has been shown to have a similar effect on the heart and blood vessels as these stimulants. It also stimulates the central nervous system in a manner similar to that of theobromine. Theophylline has shown some benefit in congestive heart failure patients but has not been proven effective for treating high blood pressure or fibrillation.

  • Phenyl vinylketone

    CAS :
    <p>Phenyl vinylketone is a substance that belongs to the group of organic compounds called vinyl. This compound has been shown to have biological properties. Phenyl vinylketone is synthesized by an intramolecular hydrogen-transfer reaction between the hydroxyl group and the ketone group in a molecule. The phenyl vinylketone can be found in receptor cells, which are cells that detect changes in the environment. The kinetic data for this compound shows that a high dose of phenyl vinylketone inhibits cell proliferation, but does not cause cell death. Phenyl vinylketone is not metabolized and interacts with other substances through ester linkages.</p>
