Pharmacological effects of non-steroidal antiinflammatory agents on prostaglandin and leukotriene synthesis in mouse peritoneal macrophages.
Resident mouse peritoneal macrophages, exposed to zymosan, synthesized and released products of both the cyclooxygenase and lipoxygenase pathways. The effects of various non-steroidal antiinflammatory agents were evaluated for their abilities to inhibit zymosan-stimulated prostaglandin E2 (PGE2) and leukotriene C4 (LTC4) synthesis. The order of potencies to inhibit PGE2 synthesis and release was: indomethacin greater than or equal to sulindac sulfide greater than ibuprofen greater than or equal to aspirin greater than 3-amino-1-[3-(trifluoromethyl)-phenyl]-2-pyrazoline (BW755C) greater than benoxaprofen greater than or equal to nordihydroguaiaretic acid (NDGA) greater than 5,8,11-eicosatriynoic acid (ETYA). BW755C and ETYA also inhibited zymosan-stimulated LTC4 production. None of the compounds tested showed selective inhibition of lipoxygenase products.
