    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

    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.
