专利号:US-5847150-A 优先权日:1996-04-24 标题 :Solid phase and combinatorial synthesis of substituted 2-methylene-2, 3-dihydrothiazoles and of arrays of substituted 2-methylene-2, 3-dihydrothiazoles 发明人:DORWALD FLORENCIO ZARAGOZA 权利人:NOVO NORDISK AS 摘要:A solid phase method for the synthesis of a plurality of differently substituted 2-methylenethiazoles with a wide variety of side-chain substituents as compounds of potential therapeutic interest. The 2-methylenethiazoles are prepared by acylation of a substrate-bound primary or secondary amine with cyanoacetic acid and reaction of the resulting cyanoacetamide with an isothiocyanate in the presence of a base. Alkylation with an appropriate alkyl halide under acidic conditions yields differently substituted, support-bound 2-methylene-2,3-dihydrothiazoles. These may be screened on the substrate or cleaved from the substrate and then screened in solution. The efficient synthesis of a wide variety of 2-methylenethiazoles using automated synthesis technology of the present method makes these compounds attractive candidates for the generation and rapid screening of diverse thiazole-based libraries. The method disclosed here provides an easy and fast access to highly diverse heterocyclic compounds of therapeutic interest, amenable to automatization.

专利号:US-2011015119-A1 优先权日:2009-06-24 标题:Novel semi-synthetic glycopeptides as antibacterial agents 发明人:CHU DANIEL; YE TAO; WANG BING 权利人:LEAD THERAPEUTICS INC 摘要:Semi-synthetic glycopeptides having antibacterial activity are described, in particular, the semi-synthetic glycopeptides described herein are made by chemical modification of a glycopeptide (Compound A, Compound B, Compound H or Compound C) or monosaccharide made by hydrolyzing the disaccharide moiety of the amino acid-4 of the parent glycopeptide in acidic medium to give the amino acid-4 monosaccharide; conversion of the monosaccharide to the amino-sugar derivative; acylation of the amino substituent on the amino acid-4 amino-substituted sugar moiety on these scaffolds with certain acyl groups; and conversion of the acid moiety on the macrocyclic ring of these scaffolds to certain substituted amides. Key reaction is the treatment of properly protected intermediate compound with isocyanate. Also provided are methods for the synthesis of the compounds, pharmaceutical compositions containing the compounds, and methods of use of the compounds for the treatment and/or prophylaxis of diseases, especially bacterial infections.
