| 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 | 在LNCaP细胞系中对21-deoxycortisol（21dF）和21-deoxycortisone（21dE）进行检测，以证实CYP17A1的裂解活性催化了这一转换过程。CYP17A1转染后，11-Beta-hydroxyandrostenedione（11OHA4）途径的代谢产物增加，实际上21dF和21dE分别被CYP17A1代谢成11-Beta-hydroxyandrostenedione和11-ketoprogesterone（11KP4）[2]。 |
| In vivo | 在21-羟化酶缺乏症、库欣综合症和肾上腺源性高雄激素症中，11-Beta-hydroxyandrostenedione 的血浆浓度非常高。在先天性11-羟化酶缺乏症和肾上腺功能不足中，11-Beta-hydroxyandrostenedione 的血浆浓度非常低。因此，当血浆4-雄烯二酮浓度升高时，测量血浆11-Beta-hydroxyandrostenedione 水平有助于确定高雄激素血症的肾上腺或卵巢来源[1]。 |
