Aurantiamide acetate was isolated from the fermentation broth of Aspergillus penicilloides for the first time. Aurantiamide acetate inhibited cysteine proteinases, in particular, cathepsin L (3.4.22.15) and B (3.4.22.1) with IC₅₀ of 12 μM and 49 μM, respectiveiy. In the adjuvant-arthritic rat model, subcutaneously administered 10 mg/kg body weight of this compound suppressed hind paw swelling.
