[Toxicity]

An adrenocortical steroid with modest glucocorticoid and mineralocorticoid activity. It is the primary glucocorticoid in the rat.
Hazard InformationBack Directory
[Description]

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.
[Chemical Properties]

white to light yellow powder
[Uses]

Corticosteroid is an activator of MCR.
[Uses]

Glucocorticoid; an intermediate in the biosynthesis of aldosterone, isolated from the adrenal cortex.
[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.
[General Description]

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.
[Biological Activity]

Endogenous glucocorticoid that acts as an agonist at glucocorticoid and mineralocorticoid receptors.
[Biochem/physiol Actions]

The complex of corticosterone with 2-hydroxypropyl-β-cyclodextrin (HBC) improves water solubility. HBC is a carrier molecule. Corticosterone is a rodent-specific primary adrenal corticosteroid. It displays affinity towards the glucocorticoid and mineralocorticoid receptors.

Room temperature
[Purification Methods]

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.
