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

Macrolide antibiotics are mechanism-based inactivators of CYP3A enzymes that exhibit varying degrees of inhibitory potency. Our aim was to predict quantitatively the drug-drug interaction (DDI) potential of five macrolides from in vitro studies using testosterone as the CYP3A substrate, and

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

Cytochrome P450 (P450) reaction phenotyping is a key process toward accurately determining the contribution of different P450s to the metabolism of new chemical entities. The significance of P450s to drug disposition has led to the identification of selective chemical and
