The anti-inflammatory effects of auranofin were studied and compared with those of indomethacin, gold sodium thiomalate (GST) and D-penicillamine. Auranofin was active as indomethacin in inhibiting carrageenan induced paw edema in rats, but was less potent than indomethacin in inhibiting UV-induced erythema in guinea pigs. Auranofin inhibited Arthus type paw edema and reverse PCA reaction in rats, on which indomethacin was ineffective. The inhibitory activity of auranofin on adjuvant arthritis was weaker than that of indomethacin. In in vitro experiments, auranofin did not show any suppression of cyclooxygenase activity, but was capable of suppression of lysosomal enzyme release and chemotaxis of neutrophils and macrophages. In addition to these anti-inflammatory activities, auranofin had almost equal anti-analgesic and anti-pyretic activity to that of indomethacin. The above results indicated that the anti-inflammatory profiles of auranofin and indomethacin differ, so we can expect new therapeutic activities of auranofin. GST had similar anti-inflammatory and anti-analgesic profiles to those of auranofin; however, the activities were less potent than auranofin and devoid of anti-pyretic activity. D-penicillamine did not show any anti-inflammatory, anti-analgesic or anti-pyretic activity.
