Deoxycorticosterone (11-deoxycorticosterone, 21-hydroxyprogesterone; also called cortexone or desoxycortone) is an endogenous steroid hormone made by the adrenal cortex that functions both as a mineralocorticoid and as the metabolic precursor to a potent neurosteroid. Acting through the mineralocorticoid receptor (a ligand-activated transcription factor that governs sodium and water balance), it promotes renal salt retention with an affinity close to that of aldosterone. Its principal relevance to neuropharmacology is as the parent compound of 3-alpha,5-alpha-tetrahydrodeoxycorticosterone (THDOC), a positive allosteric modulator of the GABA-A receptor (the brain's main inhibitory chloride channel) that is released during stress and shapes seizure threshold, anxiety, and hypothalamic-pituitary-adrenal (HPA) axis activity. Deoxycorticosterone should not be confused with the psychedelic amphetamine also abbreviated DOC (2,5-dimethoxy-4-chloroamphetamine), which is an entirely unrelated compound.

Overview
An endogenous adrenal mineralocorticoid whose main neuropharmacological significance is as the biosynthetic precursor to the stress-derived GABA-A neurosteroid THDOC.
- Deoxycorticosterone binds the mineralocorticoid receptor with roughly the same affinity as aldosterone (dissociation constant near 1 nanomolar), yet it is usually a minor mineralocorticoid except in pregnancy and specific enzyme-deficiency states.
- During the third trimester of pregnancy, maternal plasma deoxycorticosterone rises to between 4 and 50 times nonpregnant levels, partly from 21-hydroxylation of circulating progesterone outside the adrenal gland.
- After stress, the deoxycorticosterone metabolite THDOC can switch from inhibitory to excitatory at hypothalamic CRH neurons, because stress dephosphorylates the KCC2 chloride transporter and collapses the chloride gradient, which helps activate the stress axis.
- 11-beta-hydroxylase deficiency causes deoxycorticosterone to accumulate and produce hypertension, the opposite of the salt-wasting hypotension seen in the far more common 21-hydroxylase deficiency.
Mechanism
Deoxycorticosterone occupies a pivotal branch point in adrenal steroidogenesis and doubles as the precursor to a stress-responsive neurosteroid. Biosynthesis begins when steroid 21-hydroxylase (CYP21A2, a cytochrome P450 enzyme of the endoplasmic reticulum) hydroxylates progesterone at carbon 21 to yield deoxycorticosterone; deficiency of this same enzyme underlies most cases of congenital adrenal hyperplasia (an inherited defect of adrenal steroid synthesis). From this node, 11-beta-hydroxylase (CYP11B1) converts deoxycorticosterone to corticosterone in the zona fasciculata, while aldosterone synthase (CYP11B2) carries it through corticosterone and 18-hydroxycorticosterone to aldosterone in the zona glomerulosa. Deoxycorticosterone is also generated outside the adrenal by 21-hydroxylation of circulating progesterone, a route that becomes quantitatively important during pregnancy.
The hormone's primary action is agonism at the mineralocorticoid receptor (MR, a -activated transcription factor governing epithelial sodium and water transport), which it binds with an affinity close to that of aldosterone (dissociation constant near 1 nanomolar). This drives renal sodium reabsorption and potassium excretion and, in excess, hypertension and hypokalemia; deoxycorticosterone has only weak intrinsic glucocorticoid-receptor activity.
The neuropharmacological importance of deoxycorticosterone derives from its two-step reduction to a neurosteroid. 5-alpha-reductase (chiefly the type I isoform) reduces deoxycorticosterone to 5-alpha-dihydrodeoxycorticosterone (5-alpha-DHDOC), and 3-alpha-hydroxysteroid dehydrogenase (3-alpha-HSD) then forms 3-alpha,5-alpha-tetrahydrodeoxycorticosterone (THDOC, allotetrahydrodeoxycorticosterone). THDOC is a potent positive modulator of the -A receptor (the brain's principal inhibitory chloride ion channel), enhancing GABA-gated chloride current at low nanomolar concentrations and directly gating the channel at higher concentrations. It is especially effective at extrasynaptic GABA-A receptors that contain the delta subunit and mediate tonic inhibition (a persistent background inhibitory conductance that sets neuronal excitability). Neurosteroids of this class act at transmembrane sites distinct from the benzodiazepine and barbiturate sites; potentiation arises from a cavity within the receptor's alpha subunit, whereas direct activation is initiated at a pocket between the alpha and beta subunits. The biosynthetic enzymes are expressed mainly in principal projection neurons, including cortical and hippocampal pyramidal cells, thalamic and striatal output neurons, and cerebellar Purkinje cells, rather than in local interneurons. The intermediate 5-alpha-DHDOC retains GABA-A activity of its own.
These pathways couple the endocrine stress response to neuronal excitability. Acute stress raises plasma deoxycorticosterone and brain THDOC to concentrations that -A receptors and elevate seizure threshold, giving deoxycorticosterone-derived neurosteroids an endogenous anticonvulsant and anxiolytic role. At corticotropin-releasing hormone neurons of the hypothalamic paraventricular nucleus, however, THDOC can become excitatory after stress, because stress-driven dephosphorylation of the KCC2 chloride transporter collapses the transmembrane chloride gradient so that delta-subunit GABA-A currents depolarize these cells and help activate the . Deoxycorticosterone-derived neurosteroids therefore behave as bidirectional feedback regulators of the stress system, a mechanism implicated in epilepsy, anxiety, depression, and the perimenstrual (catamenial) worsening of seizures.

Safetyrisks and cautions, not medical advice
Deoxycorticosterone is a physiological hormone rather than a consumer supplement, and its safety profile is defined chiefly by mineralocorticoid excess. Sustained elevation, as seen in 11-beta-hydroxylase deficiency (a hypertensive form of congenital adrenal hyperplasia), in rare deoxycorticosterone-secreting adrenal tumors, or during pharmacological deoxycorticosterone acetate (DOCA) administration, drives sodium and water retention, potassium loss, suppression of plasma renin and aldosterone, hypertension (high blood pressure), hypokalemia (low blood potassium), and metabolic alkalosis.
These effects can strain the cardiovascular system and kidneys. Because deoxycorticosterone binds the mineralocorticoid receptor as strongly as aldosterone, even modest chronic excess is clinically meaningful. The neurosteroid metabolite THDOC, by contrast, produces sedation, anxiolysis, and anticonvulsant effects through the GABA-A receptor, so conditions that raise deoxycorticosterone-derived neurosteroids may also alter arousal and seizure threshold. Deoxycorticosterone itself is not used as a nootropic and is not available over the counter.
History
Deoxycorticosterone was among the first adrenocortical steroids to be isolated and characterized. Its acetate ester, deoxycorticosterone acetate (DOCA; marketed as Percorten), was synthesized by Reichstein and colleagues in the late 1930s from desoxycholic acid and was the first crystalline adrenal cortical hormone available in therapeutic quantities. Introduced around 1938 to 1939, DOCA served as the mainstay mineralocorticoid replacement for Addison's disease (primary adrenal insufficiency) until the synthetic mineralocorticoid fludrocortisone superseded it; it corrected the sodium and chloride wasting of adrenal failure but not the accompanying glucocorticoid deficiency.
In experimental medicine, chronic DOCA together with a high salt intake became the classic DOCA-salt model of mineralocorticoid hypertension. Scientific interest in deoxycorticosterone was renewed from the 1980s onward, when work on neuroactive steroids showed that its reduced metabolite THDOC is a GABA-A receptor modulator whose brain concentrations rise during stress.
Reputation
Within endocrinology, deoxycorticosterone is regarded as a biochemically important intermediate and a useful diagnostic marker; elevated serum deoxycorticosterone helps flag the hypertensive 11-beta-hydroxylase and 17-alpha-hydroxylase forms of congenital adrenal hyperplasia and distinguishes them from the more common salt-wasting 21-hydroxylase deficiency. In neuroscience it is known largely by proxy, through its metabolite THDOC, as a member of the stress-responsive neurosteroid family alongside allopregnanolone. It holds no standing as a recreational or nootropic agent and is essentially absent from the supplement market. The historical DOCA is now mainly of veterinary interest, where the long-acting ester deoxycorticosterone pivalate remains a mineralocorticoid replacement for canine hypoadrenocorticism.
Subjective profileweighing the evidence above
Not something to take. It matters as biology, sitting directly upstream of the calming neurosteroid THDOC, but as a drug it is a potent mineralocorticoid, and excess means high blood pressure, potassium loss and fluid retention. The interesting part is downstream of it.

FAQ
Is deoxycorticosterone the same as the psychedelic DOC?
No. The abbreviation DOC is shared by two unrelated substances. Deoxycorticosterone is an endogenous adrenal steroid hormone and neurosteroid precursor, whereas the psychedelic DOC is 2,5-dimethoxy-4-chloroamphetamine, a synthetic hallucinogenic phenethylamine with no structural or pharmacological relationship to the steroid.
Is deoxycorticosterone itself a neurosteroid?
It is best described as a neurosteroid precursor. The hormone itself acts mainly on the mineralocorticoid receptor, but the brain and other tissues reduce it in two enzymatic steps to THDOC, which is the pharmacologically active GABA-A neurosteroid.
Why does an adrenal salt hormone matter to the brain?
Under stress, adrenal output of deoxycorticosterone rises and a fraction is reduced to THDOC in the brain, reaching concentrations that potentiate GABA-A receptors. This links the stress endocrine system to neuronal excitability, seizure threshold, anxiety, and feedback control of the HPA axis.
Can deoxycorticosterone be taken as a supplement?
No. Deoxycorticosterone is not sold as an over-the-counter supplement, unlike some other endogenous steroids such as DHEA or pregnenolone. Its historical medical form, deoxycorticosterone acetate, was a prescription mineralocorticoid, and a long-acting ester is still used in veterinary medicine.
What causes deoxycorticosterone levels to rise?
Pregnancy, acute stress, 11-beta-hydroxylase or 17-alpha-hydroxylase deficiency, and rare deoxycorticosterone-secreting adrenal tumors all elevate it. In the enzyme-deficiency and tumor states the excess mineralocorticoid activity typically produces hypertension and low potassium.
