, although it is not as potent. The hormone causes increased breakdown of proteins and decreased protein synthesis, and large doses given over a long period of time may result in inhibited growth in children or weakening of bones and wasting of muscles in adults.

The principal medical use of cortisone comes from its anti-inflammatory and antiallergic effects; it is extremely useful in the treatment of innumerable diseases including asthma and other allergic reactions, arthritis, and various skin diseases. Cortisone is necessary to maintain life and enable the organism to respond to stress; failure of the adrenal glands to synthesize cortisone (Addison's disease) or surgical removal of the adrenals is fatal unless cortisone is given as replacement therapy. Although less cortisone is manufactured in the body than either cortisol or corticosterone and although cortisone is less potent than cortisol, the term cortisone is often used collectively to include the other glucocorticoids, both the naturally occurring and the synthetic compounds such as prednisone. Small quantities of cortisone were first isolated from animal adrenals in 1935–36. A method of manufacture, involving laboratory synthesis from an acid of bilebile,

, was developed, and in 1949 cortisone was first offered commercially. The specific mechanisms by which cortisone and similar compounds act are still poorly understood.

C21H28O5, one of the active corticosteroids. Colorless crystals; melting point, 215°C; poorly soluble in organic solvents.

Cortisone is isolated from adrenal extracts. Its chemical structure was elucidated by the Swiss chemist T. Reichstein (1936–40) and confirmed by complete synthesis. In animals and man, cortisone is secreted in small quantities into the blood by the adrenals. Once regarded as an adrenocortical hormone, it is now considered a product of the conversion of hydrocortisone.

Cortisone is a glucocorticoid in its biological action: it stimulates the synthesis of carbohydrates from proteins, depresses the lymphoid organs, and has relatively little effect on mineral metabolism. Cortisone acetate is used as a hormonal preparation in substitution therapy for adrenocortical insufficiency and as an anti-inflammatory and antiallergic agent in rheumatic carditis, polyarthritis, and bronchial asthma. Cortisone has been almost completely replaced in modern medical practice by more effective synthetic corticosteroids. It is obtained industrially from steroids of plant and animal origin by complex chemical and microbiological conversions.

With endogenous cortisol production, the cortisone concentration in the saliva is usually higher than the cortisol concentration, and typically the cortisol-to-cortisone ratio is <1, owing to the transfer of cortisone from the plasma and the conversion of cortisol to cortisone by 11-[beta]-hydroxysteroid dehydrogenase type 2 (11-[beta]-HSD2) in the salivary gland (2, 3).
