| | Cortisone acetate Usage And Synthesis |
| Description | Cortisone acetate is a synthetic glucocorticoid with anti-inflammatory properties. It decreases the size of Bacillus Calmette-Guérin (BCG) vaccine-induced dermal lesions and tuberculin reactions in rabbits when administered at 2 mg/kg on alternate days over the course of 46 days. It also reduces the number and percentage of activated lesion-infiltrating mononuclear cells and decreases the amount of caseous necrosis and ulceration. Cortisone acetate (2.5 mg/kg per day, s.c.) slows tissue regeneration in a rabbit model of wound healing. It also decreases the number of dexamethasone binding sites on isolated human lymphocytes by 30%. Formulations containing cortisone acetate have been used to relieve inflammation, pruritic manifestations of corticosteroid-responsive dermatoses, and in the treatment of immune and allergic disorders. | | Chemical Properties | White needle crystal or crystalline powder (acetone), odorless. Stable in the air. Mp239- 241°C, specific rotation [α]20D+164°(0.5%, acetone), [α]23D+169°(chloroform), [α]25D+208°-+217°(dioxane), The ethanol solution of this product has a maximum absorption at a wavelength of 240nm. Soluble in chloroform (1:4), soluble in acetone (1:75), slightly soluble in ethanol and ether, and hardly soluble in water. This product dissolves in sulfuric acid and turns yellow without fluorescence (different from hydrocortisone acetate). | | Originator | Cortone Acetate,MSD,US,1950 | | Uses | Cortisone Acetate (Hydrocortisone Acetate EP Impurity D) is a glucocorticoid. Cortisone Acetate is an antiinflammatory agent. Cortisone Acetate is bioavailable and readily converted to the therapeutically active form, Hydrocotisone. | | Preparation | Cortisone acetate is prepared from dehydropregnenolone by epoxidation, Wolff's oxidation, mycoxidation, chromic acid oxidation, hydrogen bromide ring-opening, Raney's nickel-catalyzed debromination, iodination, and acetyloxy substitution. | | Definition | ChEBI: Cortisone acetate is a corticosteroid hormone. | | Therapeutic Function | Glucocorticoid | | General Description | Cortisone acetate, 21-(acetyloxy)-17-hydroxypregn-4-ene-3,11,20-trione, is the 21-acetate of naturally occurring cortisone with good systemicanti-inflammatory activity and low-to-moderate salt-retentionactivity after its in vivo conversion to hydrocortisoneacetate. This conversion is mediated by 11β-hydroxysteroiddehydrogenase. It is used for the entire spectrum of uses discussedpreviously under the heading, “Therapeutic Uses ofAdrenal Cortex Hormones”—collagen diseases, Addisondisease, severe shock, allergic conditions, chronic lymphocyticleukemia, and many other indications. Cortisone acetateis relatively ineffective topically, mainly because itmust be reduced in vivo to hydrocortisone. Its plasma halflifeis only about 30 minutes, compared with 90 minutes to3 hours for hydrocortisone. | | Purification Methods | Crystallise -1cortisone-21-acetate from acetone or CHCl3. The UV has 15,800 M-1cm at 238nm in dioxane. [Sarett J Biol Chem 162 601 1946, Beilstein 8 III 4058, 5 IV 3481.] | | References | 1.
