专利号:US-4778805-A 优先权日:1987-06-18 标题:4,7-benzofurandione derivatives useful as inhibitors of leukotriene synthesis 发明人:ADAMS JULIAN; GUINDON YVAN; BELANGER PATRICE C; BELLEY MICHEL L; ROKACH JOSHUA 权利人:MERCK FROSST CANADA 摘要:4,7-Benzofurandione derivatives of Formula I, pharmaceutical compositions, and methods of treatment are disclosed. These compounds are useful as inhibitors of mammalian leukotriene biosynthesis. As such, these compounds are useful therapeutic agents for treating allergic conditions, asthma, cardiovascular disorders, inflammation, psoriasis and allergic conjunctivitis. The compounds are also useful as analgesics and as cytoprotective agents. Also disclosed are novel intermediates useful for the preparation of the 4,7-benzofurandiones of this invention. ##STR1##
