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.

  • (6R)-6-Cyclopentyl-6-[2-(2,6-diethyl-4-pyridinyl)ethyl]-3-[(5,7-dimethyl[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)methyl]-5,6-dihydro-4-h ydroxy-2H-pyran-2-one

    CAS :
    <p>Fidovirsen is a nucleoside analogue that is an inhibitor of the NS3 protease of hepatitis C virus (HCV). Fidovirsen binds to the active site of the NS3 protease and prevents cleavage at the NS3/4A interface, thus inhibiting viral replication. It has been shown to be effective in clinical studies involving human liver samples. Fidovirsen has also been shown to have antiviral activity against other RNA viruses, including HIV-1 and influenza A virus. Fidovirsen has a low toxicity profile and does not exhibit cross-resistance with other antiviral drugs. The drug is being developed as a potential therapy for chronic HCV infection.</p>

  • 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>

    Produit contrôlé
    CAS :
    7a,12a-Dihydroxylcholest-4-en-3-one is a structural analog of 7α,12α-dihydroxycholesterol. It has been studied for its catalytic mechanism and cavity. It is formed from the reaction of glutamate with cholesterol in a homogenate. The enzyme responsible for this biosynthesis is HMG CoA reductase, which converts 3 hydroxymethylglutaryl coenzyme A to mevalonate. Biochemical studies have shown that 7α,12α-dihydroxylcholest-4-en-3-one is metabolized by the liver into bile acids and excreted in the urine. This compound has also been shown to be an antiinflammatory agent due to its ability to inhibit prostaglandin synthesis and reduce inflammation.
