标题 :Synthesis of cyclic peptides
发明人：SMYTHE MARK LESLIE; MEUTERMANS WIM DENIS FRANS; BOURNE GREGORY THOMAS; MCGEARY ROSS PETER

摘要:This invention relates to methods for preparing cyclic peptides and peptidomimetic compounds in solution and bound to solid supports, and to cyclic peptide or peptidomimetic libraries for use in drug screening programs. In particular, the invention relates to a generic strategy for synthesis of cyclic peptides or peptidomimetics that enables the efficient synthesis under mild conditions of a wide variety of desired compounds. Two approaches were evaluated for their improvements in solution and solid phase synthesis of small cyclic peptides: positioning reversible N-amide substituents in the sequence; and applying native ligation chemistry in an intramolecular sense. Systematic investigation of the effects of preorganising peptides prior to cyclisation by using peptide cyclisation auxiliaries, and developing new linkers and peptide cyclisation auxiliaries to aid cyclic peptide synthesis gives surprising improvements in both yields and purity of products compared to the prior art methods. The combination of these technologies provides a powerful generic approach for the solution and solid phase synthesis of small cyclic peptides. The ring contraction and N-amide substitution technology of the invention provide improved methods for the synthesis of cyclic peptides and peptidomimetics. When used in conjunction with linker strategies, this combination provides solid-phase avenues to cyclic peptides and peptidomimetics.

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 1,2,3-triazoles with a wide variety of side-chain substituents as compounds of potential therapeutic interest. The 1,2,3-triazoles are prepared by acylation of a substrate-bound primary or secondary amine with a 3-oxoalkanoic acid and reaction of the resulting amide with a primary amine under dehydrating conditions to give an enamine. Treatment of this substrate-bound enamine with a sulfonyl azide in the presence of a base gives the corresponding 1,2,3-triazoles. 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 1,2,3-triazoles using automated synthesis technology of the present method makes these compounds attractive candidates for the generation and rapid screening of diverse triazole-based libraries. The method disclosed here provides an easy and fast access to highly diverse heterocyclic compounds of therapeutic interest, amenable to automatization.
