标题 :Solid phase and combinatorial synthesis of substituted thiophenes and of arrays of substituted thiophenes
发明人:DOERWALD FLORENCIO ZARAGOZA
权利人:NOVO NORDISK AS
摘要:A solid phase method for the synthesis of a plurality of differently substituted thiophenes with a wide variety of side-chain substituents as compounds of potential therapeutic interest. The thiophenes are prepared by reaction of a substrate-bound primary or secondary amine with a thiophosgene equivalent and reaction of the resulting intermediate with an acceptor-substituted acetonitrile in the presence of a base. Alkylation with an appropriate alkyl halide, followed by Thorpe-Ziegler-cyclization yields differently substituted, support-bound 3-aminothiophenes. These may be screened on the substrate or cleaved from the substrate and then screened in solution. Alternatively, the resin-bound 3-amino thiophenes or the synthetic intermediates can be subjected to further synthetic transformations (N-acylation, reduction) on the support, which permits the preparation of further therapeutically interesting compounds. The efficient synthesis of a wide variety of thiophenes using automated synthesis technology of the present method makes these compounds attractive candidates for the generation and rapid screening of diverse thiophene-based libraries. The method disclosed here provides an easy and fast access to highly diverse heterocyclic compounds of therapeutic interest, amenable to automatization.

摘要:A solid phase method for the synthesis of a plurality of differently substituted thiophenes with a wide variety of side-chain substituents as compounds of potential therapeutic interest is disclosed. The thiophenes 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, followed by Thorpe-Ziegier-cyclization yields differently substituted, support-bound 3-aminothiophenes. These may be screened on the substrate or cleaved from the substrate and then screened in solution. Alternatively, the resin-bound 3-amino thiophenes or the synthetic intermediates can be subjected to further synthetic transformations (N-acylation, reduction) on the support, which permits the preparation of further therapeutically interesting compounds.

标 题:Post-cleavage sulfur deprotection for convergent protein synthesis by chemical ligation

权利人:AMYLIN PHARMACEUTICALS INC
摘要:The present invention provides a method and compositions for synthesizing an oligopeptide or polypeptide by convergent assembly of a plurality of pairs of oligopeptides in chemical ligation reactions. An important aspect of the present invention is an oligopeptide having a C-terminal disulfide-protected carboxythioester group that can be deprotected to spontaneously generate a free C-terminal thioester moiety. This allows a single precursor to participate in a succession of chemical ligation reactions, thereby making the convergent synthesis approach possible. The present invention is useful in methods for chemical synthesis of oligopeptides, polypeptides and proteins, and improves the efficiency of native chemical ligation reactions, particularly where four or more peptide fragments are used to assemble an oligopeptide, polypeptide or protein product.

标 题 :Method for synthesis of proteins
发明人:TAM JAMES P
权利人:UNIV VANDERBILT
摘要:A method for peptide synthesis is disclosed that requires neither protecting groups nor activation of the C-α carboxyl groups. The method comprises ligating a first molecule to a second molecule by promoting the orthogonal coupling of the molecules to each other. In an aspect of this method, an acyl-type reaction occurs between the molecules. The method contemplates the joining of molecules of variant size to each other, as well as the coupling of multiple identical molecules. The invention also covers the ligation of unprotected peptide, proteins or nonpeptide segments to prepare therapeutic products and synthetic vaccines with linear, circularized, or branched backbone structures, as well as the site-specific modification of peptides or proteins by lipidation and pegylation.
