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.

  • (2E)-1-(2-Hydroxyphenyl)-3-phenyl-2-propen-1-one

    CAS :
    The 2-hydroxyphenyl-3-phenylpropenal (HPPA) is a fatty acid with a hydroxyl group. It has been shown to have anti-inflammatory properties and inhibit the production of TNF-α in mice. HPPA is synthesized by the oxidation of oleic acid, which can be catalyzed by a number of different enzymes such as lipoxygenases, cyclooxygenases, or cytochrome P450s. The synthesis can also be inhibited by other substances such as dibromides or tnf-α. HPPA also has potent inhibitory activity against transcription polymerase chain reaction and protein synthesis. This inhibition is due to its carbonyl group that reacts with the intramolecular hydrogen on the enzyme's active site. The reaction mechanism for this inhibition is similar to that of propranolol, another drug used for treatment of inflammatory diseases.
