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.
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

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
A method is described for the preparation of two types of multi-labeled 6 beta-hydroxycortisol containing either five deuterium atoms at C-19 methyl and C-1 methylene or four 13C atoms at C-1, C-2, C-4, and C-19 in addition to the five

To investigate the pharmacokinetic interaction between cyclosporin A (CsA) and docosahexaenoic acid (DHA) in vivo, 5 mg/kg CsA was orally or intravenously coadministered with DHA (50-200 microg/kg) to rats. The effect of DHA on CYP3A activity was determined using rat
This paper describes the development of a high-throughput method for the analysis of cytochrome P450 (CYP) inhibition assay incubation samples using laser diode thermal desorption interfaced with atmospheric pressure chemical ionization mass spectrometry (LDTD-APCI-MS). Data for the CYP isoforms 3A4
