Prednisolone-21-acetate Chemical Properties,Usage,Production

Chemical Properties

White or almost white, crystalline powder.

Originator

Sterane, Phipharmex ,US ,1955

Uses

Synthetic corticosteroid; metabolically interconvertible with prednisone.

Uses

glucocorticoid

Definition

ChEBI: Prednisolone acetate is a corticosteroid hormone.

Manufacturing Process

To a solution of 0.85 gram of 1,4-pregnadiene-11β,17α,21-triol-3,20-dione (prednisolone) in 5 ml of pyridine are added 3 ml of acetic anhydride. The reaction mixture is allowed to stand at room temperature overnight and is then diluted with ice water. The resulting precipitate is filtered from the mixture and recrystallized from acetone-hexane. There is recovered 0.45 gram of 1,4-pregnadiene-11β,17α,21-triol-3,20-dione 21-acetate, MP 235°239°C. On recrystallization, the MP rose to 237°-239°C.

brand name

Econopred (Alcon); Meticortelone (Schering); Omnipred (Alcon); Sterane (Pfizer).

Therapeutic Function

Glucocorticoid

Biological Activity

Prednisolone Acetate (Omnipred) is a synthetic corticosteroid that is a particularly potent immunosuppressant.

Clinical Use

For rheumatoid arthritis, rheumatic fever, lupus erythematosus, scleroderma, dermatomyositis, acute lymphoblastic leukemia, etc.

Purification Methods

Recrystallise prednisolone acetate from EtOH, Me2CO, Me2CO/hexane, and it has UV with max at 243nm in EtOH. [Joly et al. Bull Soc Chim Fr 366 1958; Herzog et al. J Am Chem Soc 77 4781 1955, Beilstein 8 IV 3468.]
