AY 9944 是一種特異的膽固醇生物合成 (cholesterol biosynthesis) 抑制劑。AY 9944 抑制 7- 脫氫膽固醇 Δ7- 還原酶 (DHCR7) 酶,其 IC50 值為 13 nM。AY 9944 引起膽固醇不足和 7DHC 積累。在高劑量下,AY 9944 也可在培養(yǎng)的胚胎中抑制固醇 Δ7-Δ8 異構(gòu)酶,這會導(dǎo)致膽固醇 8-en-3β-ol 的積累。

    生物活性

    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

    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.

    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.
