Cortisone acetate (NSC49420; NSC-49420; Cortone acetate; Cortisyl; Incortin), a steroid hormone, is an acetate ester prodrug form of cortisone with glucocoriticoid and mineral corticoid activities. It has been used for the treatment for a number of different diseases, such as severe allergies or skin problems, asthma, or arthritis.
| ln Vitro |
In peripheral blood mononuclear cells (PBMC), cortisone (2.8-28,000 nM) dose-dependently reduces cortisol-induced apoptosis [1].
|
|---|---|
| ln Vivo |
In rabbits, cortisone (2 mg/kg; intramuscular every other day for two months) decreases tuberculin responses and BCG (Mycobacterium tuberculosis vaccine strain) lesions [2].

| Cell Assay |
Glucocorticoids (GCs) have been considered to regulate immune cell systems through induction of apoptosis in thymocytes and mature peripheral-blood lymphocytes. Here we report that apoptosis induced by cortisol in mitogen-activated peripheral-blood mononuclear cells (PBMC) is suppressed by cortisone, an oxidized metabolite of cortisol. Apoptosis in PBMCs is quantified by a cell death ELISA procedure, which can specifically detect fragmented DNA. Cortisol induced PBMC-apoptosis at concentrations more than 10 ng/ml (28 nM) in concanavalin A-stimulated PBMCs and cortisone suppressed this apoptosis at a concentration range of 1-10,000 ng/ml (2.8-28,000 nM) dose-dependently. Prednisone, a synthetic oxidized-GC, also suppressed the apoptosis-inducing effect of cortisol in a dose-dependent manner. Suppression of cortisol-induced apoptosis by cortisone was consistently observed in PBMCs derived from 16 healthy subjects. Examination for inhibitory activities of the steroids against [3H]dexamethasone binding to PBMCs suggested that cortisone can bind cellular GC-receptors (GC-Rs), but the affinity of cortisone to GCRs is 1/30 or less than that of cortisol. The results raised a possible role of cortisone in cortisol-mediated regulation of apoptosis in activated human PBMCs. The counteracting action of cortisone against cortisol-induced apoptosis may take place partially through intervention of GC-receptors (GC-Rs), but may also be due to unknown pathway(s) different from those mediated by cellular GC-Rs[1].

| Animal Protocol |
Animal/Disease Models: Male New Zealand white rabbits (2.1-2.4 kg) were injected with BCG six days after the first dose [2]
Doses: 2 mg/kg Route of Administration: intramuscularinjection every other day for 2 months Experimental Results: BCG lesions and tuberculosis bacteria were diminished factor reaction. diminished the number of infiltrating mononuclear cells (MN), the number of caseous necrosis and ulcers, and the percentage of β-galactosidase-positive NMs. |

| Additional Infomation |
Cortisone acetate is a corticosteroid hormone.
Cortisone acetate was first isolate in 1935 and became more widely researched in 1949. Since then, glucocorticoids such as cortisone acetate have been used to treat a number of inflammatory conditions such as endocrine, rheumatic, collagen, dermatologic, allergic, ophthalmic, respiratory, hematologic, neoplastic, edematous, and gastrointestinal diseases and disorders. Cortisone acetate was granted FDA approval on 13 June 1950. Cortisone Acetate is the acetate salt form of cortisone, a synthetic or semisynthetic analog of the naturally occurring cortisone hormone produced by the adrenal glands with anti-inflammatory and immunomodulating properties. Cortisone acetate diffuses through the cell membrane and binds to nuclear glucocorticoid receptors. The receptor-ligand complex binds to promotor regions of certain genes and initiates RNA transcription. This results in an induction of synthesis of certain anti-inflammatory proteins while inhibiting the synthesis of certain inflammatory mediators. A naturally occurring glucocorticoid that has been used in replacement therapy for ADRENAL INSUFFICIENCY and as an anti-inflammatory agent. Cortisone itself is inactive; it is converted in the liver to the active metabolite HYDROCORTISONE. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
