Cushing’s Syndrome

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 a 11β-hydroxysteroid dehydrogenase (11βHSD) isozymes inhibitor. As 4-androstenedione increases, measuring plasma 11-Beta-hydroxyandrostenedione can distinguish the adrenal or ovarian origin of hyperandrogenism.

Aminoglutethimide (DL-Aminoglutethimide) is an orally active anticonvulsant with various endocrine-related side effects. Aminoglutethimide blocks multiple steroid hormone synthesis pathways by inhibiting several cytochrome P-450-dependent hydroxylases, such as aromatase, cholesterol side-chain cleavage enzyme, 11-hydroxylase, and 18-hydroxylase, with IC₅₀ values of 0.3, 3.5, 120, and 20 μM, respectively. Aminoglutethimide reduces cortisol levels. Aminoglutethimide can be used in research on Cushing's syndrome, breast cancer, and other conditions.

Aminoglutethimide phosphate (DL-Aminoglutethimide phosphate) is an orally active anticonvulsant with various endocrine-related side effects. Aminoglutethimide phosphate blocks multiple steroid hormone synthesis pathways by inhibiting several cytochrome P-450-dependent hydroxylases, such as aromatase, cholesterol side-chain cleavage enzyme, 11-hydroxylase, and 18-hydroxylase, with IC₅₀ values of 0.3, 3.5, 120, and 20 μM, respectively. Aminoglutethimide phosphate reduces cortisol levels. Aminoglutethimide phosphate can be used in research on Cushing's syndrome, breast cancer, and other conditions.
