产品名称
4-Androsten-11β-ol-3,17-dione
产品介绍
11-Beta-hydroxyandrostenedione (4-Androsten-11β-ol-3,17-dione) 是一种主要存在于肾上腺的类固醇 (11β-羟化酶存在于肾上腺组织,但在卵巢组织中不存在)。11-Beta-hydroxyandrostenedione 是一种 11β-羟基类固醇脱氢酶 (11βHSD) 同工酶抑制剂。随着 4-androstenedione 的增加,测量血浆 11-Beta-hydroxyandrostenedione 可以区分高雄激素血症的肾上腺或卵巢起源。
生物活性

11-Beta-hydroxyandrostenedione (4-Androsten-11β-ol-3,17-dione) is a steroid mainly found in the the adrenal origin (11β-hydroxylase is present in adrenal tissue, but absent in ovarian tissue). 11-Beta-hydroxyandrostenedione is a11β-hydroxysteroid dehydrogenase (11βHSD) isozymesinhibitor. As 4-androstenedione increases, measuring plasma 11-Beta-hydroxyandrostenedione can distinguish the adrenal or ovarian origin of hyperandrogenism[1][2].

体外研究
(In Vitro)

In order to establish that this conversion is catalysed by the lyase activity of CYP17A1, 21-deoxycortisol (21dF) and 21-deoxycortisone (21dE) is assayed within the LNCaP cell line. Upon the transfection of CYP17A1, 11-Beta-hydroxyandrostenedione (11OHA4)-pathway metabolites increase, 21dF and 21dE are in fact metabolised to 11-Beta-hydroxyandrostenedione and 11-ketoprogesterone (11KP4) by CYP17A1, respectively[2].

体内研究
(In Vivo)

The plasma concentration of 11-Beta-hydroxyandrostenedione (11beta-hydroxy-4-androstene-3,17-dione) is very high in 21-hydroxylase deficiency, Cushing's syndrome, and hyperandrogenism of adrenal origin, and very low in congenital 11-hydroxylase deficiency and adrenal insufficiency. 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].
