Fluocinolone acetonide is a corticosteroid primarily used in dermatology to reduce skin inflammation and relieve itching. It is a synthetic hydrocortisone derivative. The fluorine substitution at position 9 in the steroid nucleus greatly enhances its activity. It was first synthesized in 1959 in the Research Department of Syntex Laboratories S.A. Mexico City.〔J S Mills, A. Bowers, Carl Djerassi and H.J. Ringold, Steroids CXXXVII. Synthesis of a New Class of Potent Cortical Hormones. 6α,9α-Difluoro-16α-Hydroxyprednisolone and its Acetonide, Journal of the American Chemical Society, 80, 3399-3404 (1960)〕 Preparations containing it were first marketed under the name Synalar. A typical dosage strength used in dermatology is 0.01–0.025%. One such cream is sold under the brand name Flucort-N and includes the antibiotic neomycin. Fluocinolone acetonide was also found to strongly potentiate TGF-β-associated chondrogenesis of bone marrow mesenchymal stem/progenitor cells, by increasing the levels of collagen type II by more than 100 fold compared to the widely used dexamethasone.〔Hara ES, Ono M, Pham HT, Sonoyama W, Kubota S, Takigawa M, Matsumoto T, Young MF, Olsen BR, Kuboki T.
