11β-hydroxylase

Metyrapone (NSC-25265) is an inhibitor of the enzyme STEROID 11-BETA-MONOOXYGENASE. It is used as a test of the feedback hypothalamic-pituitary mechanism in the diagnosis of CUSHING SYNDROME.

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.

Osilodrostat (LCI699) is a potent inhibitor of human 11β-hydroxylase (CYP11B1) and aldosterone synthase (CYP11B2) with IC50 values ​​of 2.5 and 0.7 nM, respectively, and has been approved by the FDA for the treatment of Cushing's disease.

Prolyl-4-hydroxylase Inhibitor 11, a novel proline 4-hydroxylase inhibitor, shows protective effects against oxidative stress and Cu(II) toxicity in Chlorella vulgaris.

Osilodrostat phosphate is a potent oral 11β-hydroxylase inhibitor.

Metyrapol is a competitive inhibitor of 11-deoxycorticosterone hydroxylation by 11β-hydroxylase.

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 derived from the adrenal glands, produced by the 11β-hydroxylation of 17α-hydroxyprogesterone. Because it lacks a hydroxyl group at the 21st position, it cannot be further converted into cortisol through normal metabolic pathways. 21-Deoxycortisol is a key biomarker and clinical diagnostic marker for congenital adrenal hyperplasia (CAH); measuring its levels aids in disease screening, diagnosis, and treatment monitoring. As a C11-oxo C21 steroid, 21-deoxycortisol may participate in the “backdoor” pathway of steroid metabolism and is associated with the formation of 11-oxoandrogens and the hyperandrogenic state seen in CAH; therefore, it is also frequently used in research on steroid metabolism and endocrine regulation.

21-Deoxycortisol-D8 isol-D8 is a deuterated compound of 21-Deoxycortisol. 21-Deoxycortisol (T36915) has a CAS number of 641-77-0. 21-Deoxycortisol (T36915) 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.

4-Androsten-11β-ol-3,17-dione-D7 is a deuterated compound of 4-Androsten-11β-ol-3,17-dione. 4-Androsten-11β-ol-3,17-dione (T14001) has a CAS number of 382-44-5. 11-Beta-hydroxyandrostenedione 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.

21-Deoxycortisol (Standard) is a reference standard for research and analysis in studies involving 21-Deoxycortisol. 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.

11-Beta-hydroxyandrostenedione (Standard) is a reference standard for research and analysis in studies involving 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.

21-Deoxycortisol-D8 (Standard) is a reference standard of 21-Deoxycortisol-D8 intended for quantitative analysis, quality control, and related biochemical research applications. 21-Deoxycortisol-d8 is a deuterated compound of 21-Deoxycortisol. 21-Deoxycortisol has a CAS number of 641-77-0. 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) is a corticosteroid metabolite of 11-ketoprogesterone. It is generated from 11-ketoprogesterone by the cytochrome P450 (CYP) isoform CYP17A1, and can also be produced by oxidation via 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) from 21-deoxycorticosterone. In patients with congenital adrenal hyperplasia, a metabolic disorder characterized by a deficiency of 21-hydroxylase, levels of 21-Deoxy Cortisone are elevated.
