The influence of esterification on the topical antiinflammatory activity of 7 alpha-chloro- and 7 alpha-bromo-16 alpha-methylprednisolones.
The effect on topical antiinflammatory potency of altering the ester functions of 7-halogenocorticosteroids was examined. Highest potencies for both 7 alpha-chloro- and 7 alpha-bromo-16 alpha-methylprednisolones were generally achieved through diesterification at the 17- and 21-positions. However, among these diesters, structure seems to be more important for topical potency than lipophilicity.
