Beschreibung

Corticosterone is a steroid hormone produced in the cortex of the adrenal glands that binds to both glucocorticoid and mineralocorticoid receptors. It is produced in response to ACTH (corticotropic hormone) and is the precursor to aldosterone synthesis. Since the production of glucocorticoids is increased by stress, it is often used as a biomarker of stress. Plasma corticosterone levels have a circadian variation and corticosterone may be important in the regulation of the sleep-wake cycle.

Chemische Eigenschaften

white to light yellow powder

Verwenden

Corticosterone: HBC complex has been used:
  • in the intravenous and intraperitoneal administration of corticosterone to rats to test its effect on glucocorticoid and mineralocorticoid activity
  • to induce acute stress in mice
  • in Pulsatile treatment in mice to test its effect on clock gene period 1 transcription

Definition

ChEBI: A 21-hydroxy steroid that consists of pregn-4-ene substituted by hydroxy groups at positions 11 and 21 and oxo groups at positions 3 and 20. Corticosterone is a 21-carbon steroid hormone of the corticosteroid type produced in the cortex of the adrenal glan s.

Allgemeine Beschreibung

Corticosterone is a corticosteroid and aldosterone precursor produced in the adrenal glands. Serum corticosterone levels are measured by LC-MS/MS for newborn screening and diagnosis of 11-hydroxylase deficiency.

Biologische Aktivit?t

Endogenous glucocorticoid that acts as an agonist at glucocorticoid and mineralocorticoid receptors.

l?uterung methode

Purify corticosterone by recrystallisation from Me2CO (trigonal plates), EtOH or isoPrOH. It has UV max at 240nm, and gives an orange-yellow solution with strong fluorescence on treatment with concentrated H2SO4. It is insoluble in H2O but soluble in organic solvents.

J Am Chem Soc 7 7 4359 1955; NMR: Shoolery & Rogers J Am Chem Soc 8 0 5121 1958.] The 21-O-acetyl derivative [1173-26-8] crystallises from Me2CO/Et2O with m 152.5-153o, [] D 20 +195o (c 0.6, Me2CO), and the 21-O-benzoyl derivative crystallises from AcOH/Et2O with m 201-202o [Reichstein Helv Chim Acta 2 0 953 1937].
