专利号:US-6362166-B1 优先权日:1996-05-14 标 题 :Antipicornaviral compounds and methods for their use and preparation 发明人:WEBBER STEPHEN E; DRAGOVICH PETER S; PRINS THOMAS J; REICH SIEGFRIED H; LITTLE JR THOMAS L; LITTLEFIELD ETHEL S; MARAKOVITS JOSEPH T; BABINE ROBERT E; BLECKMAN TED M 权利人:AGOURON PHARMA 摘要:Picornaviral 3C protease inhibitors, obtainable by chemical synthesis, inhibit or block the biological activity of picornaviral 3C proteases. These compounds, as well as pharmaceutical compositions that contain these compounds, are suitable for treating patients or hosts infected with one or more picornaviruses. Several novel methods and intermediates can be used to prepare the novel picornaviral 3C protease inhibitors of the present invention.
专利号:US-3642786-A 优先权日:1967-05-29 标题 :Merocyanine dyes 发明人:HESELTINE DONALD W; LINCOLN LEWIS L 权利人:EASTMAN KODAK CO 摘要:MEROCYANINE DYES DERIVED FROM B,B-NAPHTHOTHIAZOLE HAVE BEEN FOUND TO BE EXCELLENT SPECTRAL SENSITIZERS FOR SILVER HALIDE EMULSIONS. THESE DYES HAVE SUBSTANTIALLY THE SAME SENSITIZATION PROPERTIES AS KNOWN CORRESPONDING A-NAPTHTHOTHIAZOLE DYES. HOWEVER, THE B,B-NAPHTHOTHIAZOLE NUCLEUS DOES NOT REQUIRE THE USE OF A COARCINOGENIC INTERMEDIATE (B-NAPHTHYLAMINE) IN ITS SYNTHESIS.
