7α-Hydroxy-4-cholesten-3-one
Based on 1 Customer Validation
7α-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.

Biological Activity
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].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
