| Description | 7α-Hydroxy-4-cholesten-3-one is an intermediate in bile acid synthesis from cholesterol, a PXR agonist, and a biomarker for bile acid loss and diseases related to defective bile acid biosynthesis. It is also the physiological substrate for [CYP8B1]. |
| In vitro | 7α-Hydroxy-4-cholesten-3-one is a key intermediate in the bile acid synthesis pathway. Cytochrome P450 7A1 introduces a 7α-hydroxy group to cholesterol, and 3β-hydroxysteroid dehydrogenase then oxidizes and isomerizes the 3-hydroxy group and the Δ5,6-double bond, forming 7α-Hydroxy-4-cholesten-3-one. The absence of P450 27A1 downstream increases its concentration [1]. |
| In vivo | 7α-Hydroxy-4-cholesten-3-one significantly influences the hepatic enzyme CYP7A1 activity under steady-state conditions and during rapid diurnal fluctuations in rats. Moreover, its serum levels exhibit a marked diurnal rhythm. |
