11-Beta-hydroxyandrostenedione

11-Beta-hydroxyandrostenedione
11-Beta-hydroxyandrostenedione (NSC-17102) is a steroid mainly found in the adrenal origin (11β-hydroxylase is present in adrenal tissue, but absent in ovarian tissue), which is a 11β-hydroxysteroid dehydrogenase isozymes inhibitor. Measuring plasma 11-Beta-hydroxyandrostenedione can distinguish the adrenal or ovarian origin of hyperandrogenism with 4-androstenedione increases.

Product Introduction

Bioactivity
Description
11-Beta-hydroxyandrostenedione (NSC-17102) is a steroid mainly found in the adrenal origin (11β-hydroxylase is present in adrenal tissue, but absent in ovarian tissue), which is a 11β-hydroxysteroid dehydrogenase isozymes inhibitor. Measuring plasma 11-Beta-hydroxyandrostenedione can distinguish the adrenal or ovarian origin of hyperandrogenism with 4-androstenedione increases.
In vitro
21-deoxycortisol (21dF) and 21-deoxycortisone (21dE) are assayed within the LNCaP cell line to establish that this conversion is catalyzed by the lyase activity of CYP17A1. After the transfection of CYP17A1, 11-Beta-hydroxyandrostenedione (11OHA4)-pathway metabolites increase, 21dF, and 21dE are in fact metabolized to 11-Beta-hydroxyandrostenedione and 11-ketoprogesterone (11KP4) by CYP17A1, respectively [2].
In vivo
In 21-hydroxylase deficiency, Cushing's syndrome, and hyperandrogenism of adrenal origin, the plasma concentration of 11-Beta-hydroxyandrostenedione (11beta-hydroxy-4-androstene-3,17-dione) is very high. In congenital 11-hydroxylase deficiency and adrenal insufficiency, the plasma concentration of 11-Beta-hydroxyandrostenedione (11beta-hydroxy-4-androstene-3,17-dione) is very low. Thus, when plasma 4-androstenedione is elevated, it is useful to measure the plasma 11-Beta-hydroxyandrostenedione level in order to determine the adrenal or ovarian origin of the hyperandrogenism [1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
