专利号:US-6683189-B1 优先权日:1996-02-26 标 题 :Method for the synthesis of pyrrole and imidazole carboxamides on a solid support 发明人:DERVAN PETER B; BAIRD ELDON 权利人:CALIFORNIA INST OF TECHN 摘要:The present invention describes a novel method for the solid phase synthesis of polyamides containing imidazole and pyrrole carboxamides. The polyamides are prepared on a solid support from aromatic carboxylic acids and aromatic amines with high stepwise coupling yields (>99%), providing milligram quantities of highly pure polyamides. The present invention also describes the synthesis of analogs of the natural products Netropsin and Distamycin A, two antiviral antibiotics. The present invention also describes a novel method for the solid phase synthesis of imidazole and pyrrole carboxamide polyamide-oligonucleotide conjugates. This methodology will greatly increase both the complexity and quantity of minor-groove binding polyamides and minor-groove binding polyamide-oligonucleotide conjugates which can be synthesized and tested.

专利号:US-7589170-B1 优先权日:1998-09-25 标题 :Synthesis of cyclic peptides 发明人:SMYTHE MARK LESLIE; MEUTERMANS WIM DENIS FRANS; BOURNE GREGORY THOMAS; MCGEARY ROSS PETER 权利人:UNIV QUEENSLAND 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.

Specifically disclosed are a method for the solid-phase synthesis of a glycopeptide which comprises a step for obtaining a glycopeptide derivative wherein the N-terminus is protected, the C-terminus is immobilized to a solid phase via a silicon linker, and a reactive group carried by a sugar residue and a reactive group carried by an amino acid side chain constituting a peptide are protected by silicon-containing groups, and a step for obtaining the glycopeptide by deprotecting said glycopeptide derivative and releasing the same from the solid phase by treating the glycopeptide derivative with an agent for removing the silicon-containing groups and the silicon linker; a synthesis intermediate to be used in the step for obtaining the glycopeptide derivative in the aforesaid method; and a device for the solid-phase synthesis of a glycopeptide.
专利号:US-11661406-B2 优先权日:2018-08-13 标 题 :Method for producing intermediate useful for synthesis of SGLT inhibitor 发明人:LI QING RI; YOON HEE KYOON 权利人:DAEWOONG PHARMACEUTICAL CO LTD 摘要:A method of preparing an intermediate useful for the synthesis of a diphenylmethane derivative that can be used as an SGLT inhibitor is described. A method of synthesizing a compound of Formula 7 can address problems of existing synthesis processes requiring the synthesis of the Grignard reagent and management of related substances. In addition, the method can minimize the generation of related substances, and thus does not require reprocessing of reaction products, thereby simplifying the process. Accordingly, the production yield of a diphenylmethane derivative can be maximized.
