6β-Hydroxytestosterone has been used as a standard in high-performance liquid chromatography (HPLC) analysis to measure testosterone 6 β -hydroxylase activity in rat liver microsomes, and measure cytochrome P450 3A (CYP3A) activity in the intestinal spheroid model.
Biochem/physiol Actions
6β-Hydroxytestosterone is a CYP3A4 metabolite; androgenic.
6β-Hydroxytestosterone is a metabolite generated by brain testosterone cytochrome P450 1B1 (CYP1B1). It may elicit angiotensin II-induced neurogenic hypertension and inflammation in male mice.

Compared to two-dimensional (2D) cell culture, cellular aggregates or spheroids (3D) offer a more appropriate alternative in vitro system where individual cell-cell communication and micro-environment more closely represent the in vivo organ; yet we understand little of the physiological conditions
Previously, we showed that peripheral administration of 6β-hydroxytestosterone, a CYP1B1 (cytochrome P450 1B1)-generated metabolite of testosterone, promotes angiotensin II-induced hypertension in male mice. However, the site of action and the underlying mechanism by which 6β-hydroxytestosterone contributes to angiotensin II-induced hypertension

A rapid and sensitive radiometric assay for assessing the potential of drugs to inhibit cytochrome P450 (P450) 3A4/5 in human liver microsomes is described. In contrast to the conventional testosterone 6beta-hydroxylation assay, the new method does not require high-performance liquid

Intestinal or hepatic microsomes from channel catfish converted [4-14C]-testosterone to three major metabolites: 6 beta-hydroxytestosterone, androstenedione and a third metabolite. Formation of the unknown metabolite required NADPH as cofactor. When incubated with 200 microM testosterone, the rate of formation of
The intestinal bacterial metabolites of ginsenosides are responsible for the main pharmacological activities of ginseng. The purpose of this study was to find whether these metabolites influence hepatic metabolic enzymes and to predict the potential for ginseng-prescription drug interactions. Utilizing
