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.

  • 5-(5-Carboxy-2-ethoxyphenyl)-1-methyl-3-n-propyl-1,6-dihydro-7H-pyrazolo[4,3-d]pyrimidin-7-one

    CAS :
    <p>Sildenafil is a drug that is used to treat erectile dysfunction. It inhibits the action of phosphodiesterase type 5 (PDE-5), an enzyme that breaks down the messenger cyclic guanosine monophosphate (cGMP) within the corpus cavernosum. This leads to increased levels of cGMP, which relaxes smooth muscle cells in the corpus cavernosum and allows for more blood flow into the penis. Sildenafil is synthesized from chrysanthemum morifolium, a plant also known as "shamrock." Sildenafil has been shown to have no effects on insulin resistance or lipid metabolism, but it does cause side effects such as headache, visual disturbances, and hearing loss.</p>

  • H-Glu-Gly-Arg-chloromethylketone trifluoroacetate salt

    CAS :
    <p>H-Glu-Gly-Arg-chloromethylketone trifluoroacetate salt is an anticoagulant drug that prevents the formation of blood clots by inhibiting the enzyme thrombin. This drug is effective in enhancing blood flow and oxygen supply to the heart and other organs. H-Glu-Gly-Arg-chloromethylketone trifluoroacetate salt has been shown to have a positive effect on patients with congestive heart failure. It has also been used as an adjuvant therapy in bypassing procedures, where clotting occurs at the site of an artificial conduit placed in the body to allow blood flow between two points. In vitro studies have demonstrated that this drug inhibits protease activity, which may be due to its ability to inhibit fibrinogen and serine protease activity.</p>

  • Furfuralacetone

    CAS :
    <p>Furfuralacetone is a reaction vessel that may be used in the production of coatings. Furfuralacetone reacts with acetone and an acidic catalyst to produce furfuryl alcohol, which can be used as a raw material for the production of epoxy resins. Furfuryl alcohol and epoxy resins have been shown to have genotoxic potential. Furfuralacetone is also a reactive chemical intermediate that is produced when furfural reacts with an acid or base. This compound has been shown to react with β-unsaturated ketones in a linear plot, forming ring-opened products.</p>

    <p>Decanoyl-arginine-arginine-leucine-chloromethylketone trifluoroacetate salt is a prohormone that is biosynthesized from the amino acid decanoic acid. It has been shown to inhibit fatty acid synthesis and mineralization in tissue samples, as well as drug target enzymes such as human pathogens. Decanoyl-arginine-arginine-leucine-chloromethylketone trifluoroacetate salt has also been shown to have insulin resistance properties and may be used for the treatment of metabolic disorders.</p>

  • 1-Acetyl-6-(perfluoropropan-2-yl)-3-((pyridin-3-ylmethyl)amino)-3,4-dihydroquinazolin-2(1H)-one

    CAS :
    <p>1-Acetyl-6-(perfluoropropan-2-yl)-3-((pyridin-3-ylmethyl)amino)-3,4-dihydroquinazolin-2(1H)-one (PAFQ) is a mitochondrial cytochrome P450 inhibitor that inhibits the function of the ryanodine receptor and interacts with the piperonyl butoxide synergistically. PAFQ has been shown to be effective against animal pests such as termites, ants, and cockroaches. It also inhibits population growth in these populations by interfering with their ability to synthesize proteins. The effective dose for PAFQ varies depending on whether it is applied topically or orally.</p>

  • 3-(Hydroxymethyl)cyclopentanone

    CAS :
    <p>3-(Hydroxymethyl)cyclopentanone is a bifunctional molecule that can be used as a catalyst. It is able to catalyze the hydration of ketones and esters, which is an important reaction for the synthesis of carbocyclic nucleosides. 3-(Hydroxymethyl)cyclopentanone has been shown to react with dilithium (LiH), forming a covalent bond through its two functional groups. The long-chain nature of this molecule makes it ideal for use in hydrophobic environments such as those found in tumor cells. 3-(Hydroxymethyl)cyclopentanone also exhibits dichroism, which is caused by the different absorption of light when passing through a crystalline substance. This property can be utilized to study the stereoisomeric structure of molecules with similar chemical properties such as 5-hydroxymethylfurfural (HMF).</p>
