Chetoni

Chetoni

Le chetoni sono composti organici caratterizzati dalla presenza di un gruppo carbonile (C=O) legato a due atomi di carbonio. Questi composti sono altamente versatili e svolgono un ruolo cruciale in varie reazioni chimiche, tra cui ossidazione, riduzione e condensazione. I chetoni sono intermedi essenziali nella sintesi di prodotti farmaceutici, fragranze e polimeri. Presso CymitQuimica, offriamo una vasta gamma di chetoni di alta qualità per supportare le vostre applicazioni di ricerca e industriali.

  • 7-Hydroxy-4-cholesten-3-one-D7

    Prodotto controllato
    CAS:
    <p>7-Hydroxy-4-cholesten-3-one-D7 (7OHCD7) is a metabolite of the bile acid, cholic acid. It is generated by the action of cholesterol 7α hydroxylase on cholesterol in the liver. It is excreted in bile, which is then absorbed back into the body from the gut and used for energy metabolism. 7OHCD7 has been shown to be an inhibitor of histone deacetylases, which are enzymes that regulate gene transcription. This inhibition leads to increased transcriptional regulation and reduced inflammatory responses in bowel disease models. 7OHCD7 has also been shown to increase cholesterol levels and reduce inflammation in humans with metabolic syndrome.</p>

    Prodotto controllato
    CAS:
    <p>4-Pregnen-17a,20b-diol-3-one is a synthetic androgen with anabolic and androgenic activity. It has been shown in animal studies to increase maximal responses of the reproductive tract to gonadotropin stimulation. 4-Pregnen-17a,20b-diol-3-one binds to the activin receptor on the cell membrane, which leads to increased expression of a gene encoding for 3β-hydroxysteroid dehydrogenase (3βHSD), an enzyme involved in testosterone synthesis. This drug also increases the sensitivity of ovarian follicles to gonadotropins and decreases basal plasma levels of LH and FSH. 4-Pregnen-17a,20b-diol-3-one has not been found to be toxicologically significant at doses up to 10 mg/kg body weight per day.</p>
