AY 9944

产品介绍

AY 9944 是一种特异的胆固醇生物合成 (cholesterol biosynthesis) 抑制剂。AY 9944 抑制 7- 脱氢胆固醇 Δ7- 还原酶 (DHCR7) 酶，其 IC₅₀ 值为 13 nM。AY 9944 引起胆固醇不足和 7DHC 积累。在高剂量下，AY 9944 也可在培养的胚胎中抑制固醇 Δ7-Δ8 异构酶，这会导致胆固醇 8-en-3β-ol 的积累。

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.

体外研究

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

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay

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.

体内研究
(In Vivo)

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.

Animal Model:	Long–Evans hooded rats.
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.
