Desonide Usage And Synthesis
| Chemical Properties | Off-White Solid |
| Originator | Tridesilon,Dome,US,1972 |
| Uses | antifungal |
| Uses | Anti-inflammatory. Desonide has also been found as an impurity in budesonide (B689490). |
| Uses | Desonide(Budesonide EP Impurity F) is an impurity of Budesonide (B689490), an anti-inflammatory. |
| Definition | ChEBI: Triamcinolone acetonide with hydrogen instead of the fluorine substituent at position 9. A corticosteroid anti-inflammatory, it is used topically as a cream, ointment or lotion for the treatment of various skin disorders. |
| Indications | Desonide (DesOwen, Tridesilon) is a synthetic corticosteroid. |
| Manufacturing Process | Preparation of 11β,21-Dihydroxy-16α,17α-Isopropylidenedioxy-1,4-Pregnadiene-3,20-Dione: A solution of 11β,16α,17α,21-tetrahydroxy-1,4-pregnadiene-3,20-dione (40 mg) in acetone (10 ml) containing hydrochloricacid (three drops; d 1.19) is boiled 3n the steam bath for two minutes and then allowed to stand for eighteen hours at room temperature. The reactionmixture is diluted with water (50 ml) and extracted with chloroform (3x25ml), the combined extracts then being washed with water (30 ml) and driedover anhydrous sodium sulfate. The residue obtained by removal of solventcrystallized from ethyl acetate-petroleum ether as small plates (25 mg),melting point 257°-260°C. |
| Brand name | Desowen (Galderma); Tridesilon (Perrigo). |
| Therapeutic Function | Antiinflammatory |
