The present invention relates to the use of compounds of the formula (I) wherein the clotted line is an optional bond; R1 is butyl or butyryl if R2 is hydroxyl but is butyl if R2 is hydrogen; or R1 and R2 taken together are 1-butylidene optionally substituted by hydroxyl, methyl, or 3-(α,β-dimethylacrylyloxy)-pentylidenyl; X is a residue selected from the group consisting of X1, X2, X3, X4, and X5; wherein X is X2, X3 or X5 if the dotted line in formula (I) is absent; and X is X1, X4 or X5 if the dotted line signifies a bond in formula (I) above; R3 is hydroxyl or butyryl; and n is 1 or 2, as agents for the prevention, control and treatment of conditions requiring modulation of inflammation in mammals. In another aspect, the present invention relates to the use of compounds of the formula (I) as active ingredients in the manufacture of medicaments/compositions for the prevention, control and treatment of conditions requiring modulation of inflammation. The compounds of formula (I) as defined above may also be useful (for the manufacture of a composition) for the management of pain, fever and injuries, especially sport injuries. Moreover, the compounds of formula (I) as defined above may also be useful (for the manufacture of a composition) for the maintenance and regeneration of articular cartilage.
