The overall effect of aldosterone is to increase reabsorption of ions and water in the kidney. It has a role as a mouse metabolite and a human metabolite. It is a steroid aldehyde, a primary alpha-hydroxy ketone, a mineralocorticoid, a 21-hydroxy steroid, an 11beta-hydroxy steroid, a 20-oxo steroid, a 18-oxo steroid, a 3-oxo-Delta(4) steroid and a C21-steroid hormone. It derives from a hydride of a pregnane.

At the late distal tubule and collecting duct, aldosterone has two main actions: 1) aldosterone acts on mineralocorticoid receptors (MR) on principal cells in the distal tubule of the kidney nephron, increasing the permeability of their apical (luminal) membrane to potassium and sodium and activates their basolateral Na+/K+ pumps, stimulating ATP hydrolysis leading to phosphorylation of the pump and a conformational change in the pump exposes the Na+ ions to the outside. The phosphorylated form of the pump has a low affinity for Na+ ions, hence reabsorbing sodium (Na+) ions and water into the blood, and secreting potassium (K+) ions into the urine; 2) aldosterone stimulates H+ secretion by intercalated cells in the collecting duct, regulating plasma bicarbonate (HCO3−) levels and its acid/base balance; and 3) aldosterone may act on the central nervous system via the posterior pituitary gland to release vasopressin (ADH) which serves to conserve water by direct actions on renal tubular resorption.
BeschreibungAldosterone is a mineralocorticosteroid that takes part in the regulation of electrolytic balance in the organism. Aldosterone lowers excretion of sodium ions from the body, thus increasing their reabsorption and increasing secretion of potassium ions in renal tubules. Being a competitive antagonist of aldosterone, spironlactone blocks aldosterone receptors, thus increasing excretion of sodium, chloride, and corresponding equivalents of water with urine, thus retaining the amount of potassium ions in the organism. Spironolactone is used both individually as well as in combination with thiazides, since it lowers kaliuresis caused by thiazide diuretics.

52-39-1DTXSID7022419CHEMBL273453CHEBI:27584VerwendenLabelled Aldosterone. Aldosterone is an adrenocortical steroid which exerts regulatory influence on metabolism of electrolytes and water. Biologically active aldosterone isomer; a mineralocorticoid pr oduced by the adrenal cortex that induces urinary excretion of K+ and renal reabsorptioon of Na+. Exists as an equilibrium mixture of the aldehyde and the hemiacetal.
