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.

  • Cyclobutanone - stabilise 0.01 % BHT

    CAS :
    Cyclobutanone is a chemical compound that is used as a model system for studying the oxidation of organic compounds. Cyclobutanone can be synthesized by the reaction of trifluoroacetic acid with cyclohexanone, which in turn can be produced from the hydrogenation of acetone or by dehydration of propionaldehyde. This chemical has been shown to inhibit the growth of infectious bacteria such as Mycobacterium tuberculosis and Streptococcus pneumoniae. It is also effective against other bacterial strains, such as Escherichia coli, Salmonella typhi, and Pseudomonas aeruginosa. Cyclobutanone inhibits the metabolism of glucose in cells by blocking the enzyme hexokinase and preventing glycolysis from occurring, leading to an accumulation of lactic acid in blood and urine. This effect on glucose metabolism may contribute to some autoimmune diseases, such as type 1 diabetes mellitus and celiac disease. The structure of cycl

    Produit contrôlé
    CAS :
    3,4-Methylenedioxyphenyl butyl ketone (MBK) is a synthetic drug that is structurally related to the amphetamines. MBK has been shown to induce locomotor hyperactivity in mice and exhibits pharmacokinetic properties similar to other amphetamine-type stimulants. MBK has a high affinity for the glutamate transporter, leading to an increase in extracellular concentrations of this neurotransmitter. This may lead to neurotoxicity with repeated use. MBK also interacts with the glutamate receptor and affects glutamate homeostasis. The administration of ceftriaxone, a cephalosporin antibiotic, has been found to attenuate the effects of MBK on dopamine levels and motor activity in rats.
