Abstract The effects of auranofin (AF) and sodium aurothiomalate (GSTM) on the production of specific arachidonic acid metabolites by chemotactic tripeptide activated polymorphonuclear leukocytes has been investigated using radioimmunoassay techniques. AF insignificantly enhanced the production of leukotrienes B4 and C4 at a concentration of 0.5 microgram Au/ml. However, at increasing concentrations, this drug suppressed the production of these metabolites in a dose dependent manner. In contrast, GSTM did not affect the production of either leukotriene at the concentrations tested. Of particular interest, prostaglandin E2 production was not affected by either gold compound. Both leukotrienes and prostaglandins are metabolized from arachidonic acid and are potent mediators of inflammation. The inhibition of leukotriene production may be another mechanism by which AF manifests its antiinflammatory effects in patients with rheumatoid arthritis.
