Date Aug. 20, 1992.The present invention is novel compounds which are 4,6-di-tertiary-butyl-5-hydroxy-1,3-pyrimidine substituted 1,2,4- and 1,3,4-thiadiazoles and oxadiazoles, and 1,2,4-triazoles, and pharmaceutically acceptable additions and base salts thereof, pharmaceutical compositions and methods of use therefor. The invention compounds are now found to have activity as inhibitors of 5-lipoxygenase and/or cyclooxygenase providing treatment of conditions advantageously affected by such inhibition including inflammation, arthritis, pain, fever, and particularly rheumatoid arthritis, osteoarthritis, other inflammatory conditions, psoriasis, allergic diseases, asthma, inflammatory bowel disease, GI ulcers, cardiovascular conditions, including ischemic heart disease and atherosclerosis, and ischemia-induced cell damage, particularly brain damage caused by stroke. They can also be used topically for treating acne, sunburn, psoriasis, and eczema. Also included are leukotriene mediated pulmonary, gastrointestinal, inflammatory, dermatological, and cardiovascular conditions. The disclosed compounds also have potential utility as antioxidants. The preferred use is in treating inflammatory conditions. Thus, the present invention is also a pharmaceutical composition or method of manufacturing a pharmaceutical composition for the use of treating the noted conditions.
