Use of 7α-Hydroxy-4-cholesten-3-one7α-Hydroxy-4-cholesten-3-one is an intermediate in synthesis of bile acids from cholesterol. 7α-Hydroxy-4-cholesten-3-one is a pregnane X receptor (PXR) agonist. 7α-Hydroxy-cholest-4-en-3-one is a biomarker for bile acid loss, irritable bowel syndrome, and other diseases associated with defective bile acid biosynthesis. 7α-Hydroxy-cholest-4-en-3-one is the physiological substrate for CYP8B1[1][2]. |

| In Vitro | 7α-Hydroxy-4-cholesten-3-one is found relatively upstream in the biosynthetic pathway to bile acids (e.g. chenodeoxycholic acid). The first step is the incorporation of the 7α-hydroxy group onto cholesterol by cytochrome P450 7A1, and the second step is the oxidation and isomerization of the 3-hydroxy group and the Δ5,6-double bond by 3β-hydroxy steroid dehydrogenase to yield 7α-Hydroxy-4-cholesten-3-one. The deletion of the gene that expresses P450 27A1, which is found downstream in the bile acid pathway, results in the accumulation of the precursor, 7α-Hydroxy-4-cholesten-3-one[1]. |
| In Vivo | 7α-Hydroxy-4-cholesten-3-one strongly relates to the hepatic enzymatic activity of CYP7A1 at steady-state conditions as well as during the rapid diurnal changes that occur in the rat. That serum 7α-Hydroxy-4-cholesten-3-one has a pronounced diurnal rhythm[2]. |
