AY 9944 is a specific cholesterol biosynthesis inhibitor. AY 9944 inhibits the 7-dehydro cholesterol Δ7-reductase (DHCR7) enzyme with an IC50 of 13 nM. AY 9944 causes hypocholesterolemia and accumulation of 7DHC. At high doses, AY 9944 inhibits also in cultured embryos sterol Δ7-Δ8 isomerase, which causes the accumulation of cholest-8-en-3β-ol.

    제품 설명

    AY 9944 is a specific cholesterol biosynthesis inhibitor. AY 9944 inhibits the 7-dehydro cholesterol Δ7-reductase (DHCR7) enzyme with an IC50 of 13 nM. AY 9944 causes hypocholesterolemia and accumulation of 7DHC. At high doses, AY 9944 inhibits also in cultured embryos sterol Δ7-Δ8 isomerase, which causes the accumulation of cholest-8-en-3β-ol[1][2][3].

    IC50 & Target

    IC50: 13 nM (DHCR7)1
    In Vitro

    AY 9944 (1 μg/mL; 15 h) affects types of free sterol in keratinocytes[2].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Cell Viability Assay[2]

    Cell Line: Human foreskin keratinocytes
    Concentration: 1 μg/mL
    Incubation Time: 15 hours
    Result: Inhibited the synthesis of cholesterol and desmosterol, but increased 7-dehydrocholesterol and zymosterol synthesis.
    In Vivo

    Note:
    Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.

    AY 9944 (7.5 mg/kg; i.h. every 6 days once from postnatal day 2 to postnatal day 20) reduces brain cholesterol until 400 days after stop treatment[3].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Model: Long–Evans hooded rats[3].
    Dosage: 7.5 mg/kg
    Administration: Subcutaneous injection; 7.5 mg/kg every 6 days once; from postnatal day 2 to postnatal day 20
    Result: Reduced brain cholesterol and increased 7-dehydrocholesterol in all brain regions of rats till the treatment stopped for 400 days and showed a more severe effect on the change of sterols in plasma and liver of female rats.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
