11β-hydroxylase

11-Beta-hydroxyandrostenedione (NSC-17102) 是主要存在于肾上腺的类固醇，也是 11β-羟基类固醇脱氢酶同工酶抑制剂。随着 4-androstenedione 的提高，通过测量血浆中的11-Beta-hydroxyandrostenedione，能够区分高雄激素血症的肾上腺或卵巢起源。

Tetrahydro-11-deoxy cortisol (THS) is the primary urinary metabolite of 11-deoxycortisol. Urinary excretion of THS is elevated in patients with 11β-hydroxylase deficiency, a condition resulting from mutations in the cytochrome P450 (CYP) isoform CYP11B1. Urinary levels of THS are also elevated in patients with adrenocortical carcinoma (ACC) and adrenocortical adenoma (ACA) but are higher in patients with ACC compared to ACA.

21-Deoxycortisol is a corticosteroid metabolite of 17-hydroxyprogesterone produced in the adrenal glandvia11-hydroxylation by 11β-hydroxylase.1,2Serum levels of 21-deoxycortisol are elevated in patients with congenital adrenal hyperplasia that are heterozygous for mutations inCYP2A21, the gene encoding steroid 21-hydroxylase, and have been used as a biomarker for the detection of 21-hydroxylase deficiencies.

21-Deoxy Cortisone (21-Desoxycortisone; NSC 38722)为11-酮孕酮的一种皮质类固醇代谢产物。该化合物通过11-酮孕酮经细胞色素P450 (CYP)酶CYP17A1的作用生成，也可由21-脱氧皮质醇通过11β-羟基类固醇脱氢酶2型 (11β-HSD2) 的氧化反应形成。在先天性肾上腺增生症患者中，由于缺乏21-羟化酶，21-Deoxy Cortisone 的水平会出现上升，此症状为该遗传代谢缺陷的表现之一。
