专利号:US-6451543-B1 优先权日:1998-08-31 标题:Lipid matrix-assisted chemical ligation and synthesis of membrane polypeptides 发明人:KOCHENDOERFER GERD G; HUNTER CHRISTIE L; KENT STEPHEN B H; BOTTI PAOLO 权利人:GRYPHON SCIENCES 摘要:The present invention relates to methods and compositions for lipid matrix-assisted chemical ligation and synthesis of membrane polypeptides that are incorporated in a lipid matrix. The invention is exemplified in production of a prefolded membrane polypeptide embedded within a lipid matrix via stepwise chemoselective chemical ligation of unprotected peptide segments, where at least one peptide segment is embedded in a lipid matrix. Any chemoselective reaction chemistry amenable for ligation of unprotected peptide segments can be employed. Suitable lipid matrices include liposomes, micelles, cell membrane patches and optically isotropic cubic lipidic phase matrices. Prefolded synthetic and semi-synthetic membrane polypeptides synthesized according to the methods and compositions of the invention also permit site-specific incorporation of one or more detectable moieties, such as a chromophore, which can be conveniently introduced during synthesis. The methods and compositions of the invention have multiple uses. For example, they can be used to assay ligand binding to membrane polypeptides and domains comprising a receptor, and thus are extremely useful for structure/function studies, drug screening/selection/design, and diagnostics and the like, including high-throughput applications. The methods and compositions of the invention are particularly suited for FRET analyses of previously inaccessible membrane polypeptides.

专利号:US-12221452-B2 优先权日:2017-10-04 标题:Synthesis of cantharidin 发明人:DAVIDSON MATTHEW GENE; EKLOV BRIAN MATTHEW; WUTS PETER; LOERTSCHER BRAD MELVIN; SCHOW STEVEN R 权利人:VERRICA PHARMACEUTICALS INC 摘要:The invention provides synthetic methods for the preparation of cantharidin and analogs thereof. In one aspect, the invention provides an improved Diels-Alder cycloaddition to generate a key intermediate en route to cantharidin and analogs thereof. In certain embodiments, the new Diels-Alder reaction involves reacting Compound (2) in the presence of furan, and in the absence of acid or increased pressure, in an aprotic polar solvent with slight warming, to yield Compound (1) in favorable yield and exo-endo ratio. In another aspect, the invention also provides a new Diels-Alder reaction between compounds of Formula (III) and furan to yield compounds of Formula (IV), which can then be transformed into cantharidin or analogs thereof. In yet another aspect, the invention describes a new palladium-mediated carbonylation providing another key intermediate en route to cantharidin and analogs thereof. In addition to synthetic methods, present invention also provides compounds (i.e., intermediates) useful in the synthesis of cantharidin and analogs thereof. Compounds provided herein may have biological activity, and therefore may be used in the treatment of diseases or conditions (e.g., infectious diseases and skin conditions).
