The benzoate intermediates are readily prepared by reacting either the esters of dithiodibenzoic acid with chloride water or the 2-diazonium chloride benzoates with sulfur dioxide. The invention also provides for the total synthesis of saccharin, free of bitter tasting contaminants, from such reactants, the ultimate step in such synthesis being the ammonolysis of the o-sulfobenzoic anhydride.

专利号:WO-0053577-A9 优先权日:1999-03-12 标 题:Hydrazide inhibitors of hiv-1 integrase 发明人:NEAMATI NOURI; POMMIER YVES; LIN ZHAIWEI; BURKE TERRENCE 权利人:US GOV HEALTH & HUMAN SERV; NEAMATI NOURI; POMMIER YVES; LIN ZHAIWEI; BURKE TERRENCE 摘要:The design, synthesis and antiviral activity of novel mercaptosalicylhydrazides are disclosed, which inhibit human immunodeficiency virus type-1 integrase (HIV-1 IN), an essential enzyme for effective viral replication. Examples of the compounds are N,N'-bis(2-mercaptobenzoyl)hydrazide, N,N'-bis(2,2'-dithiosalicyl)hydrazide, and N,N'-bis(2-mercaptobenzyl)-2,2'-dithiosalicylhydrazide. These compounds are effective against the integrase catalytic core domain, inhibit integrase binding to HIV LTR DNA, and inhibit integrase in preassmbled integrase-DNA complexes. The disclosed mercaptosalicylhydrazides are 300 fold less cytotoxic than other known salicylhydrazides, and exhibit antiviral activity. They are also active in Mg+2-based assays, while integrase inhibition by salicylhydrazides is strictly Mn+2-dependent. The mercaptosalicylhydrazides have no detectable effect on other retroviral targets, including reverse transcriptase, protease, and virus attachment, and exhibit no detectable activity against human topoisomerase I at concentrations that effectively inhibited integrase. The mercaptosalicylhydrazides of the invention are therefore selective inhibitors of HIV-1 integrase, are useful in therapeutic compositions for the treatment of HIV disease, and can also be used to find related antiviral drugs.
