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-7659391-B2 优先权日:2001-11-05 标 题:Method for the in vitro synthesis of short double stranded RNAs 发明人:DE BACKER MARIANNE DENISE; HARRIS ADAM N 权利人:JANSSEN PHARMACEUTICA NV 摘要:The present invention relates to the field of synthesis of short double-stranded RNAs. An in vitro transcription method using bacteriophage polymerases and target sequence-specific single-stranded DNA oligonucleotides as templates is disclosed. The present invention finds particularly advantageous use in the synthesis of short interfering RNAs (siRNAs) that have been shown to function as key intermediates in triggering sequence-specific RNA degradation during posttranscriptional gene silencing in plants and RNA interference in invertebrates and vertebrate systems.
专利号:WO-9720061-A1 优先权日:1995-11-30 标题:Synthesis of hyaluronic acid 发明人:WONG CHI-HUEY; DELUCA CLAUDIO 权利人:SCRIPPS RESEARCH INST; WONG CHI HUEY; DELUCA CLAUDIO 摘要:A preparative enzymatic synthesis of hyaluronic acid (HA) from UDP-N-acetyl-D-glucosamine (UDP-GlcNAc) and UDP-glucuronic acid (UDP-GlcA) catalyzed by hyaluronic acid synthase is coupled with regeneration of the sugar nucleotides. Polymerizing UDP-GlcA and UDP-GlcNAc to form hyaluronic acid results in the formation of released UDP. The released UDP is, in turn, employed in the regeneration of UDP-GlcA and UDP-GlcNAc. Use of the released UDP for regenerating UDP-GlcA and UDP-GlcNAc prevents a build-up of these compounds and prevents or reduces feed back inhibition of the hyaluronic acid synthase reaction that would otherwise be caused by such build-up. Accordingly, the product yield is enhanced by the recycling of these compounds.
专利号:US-2002022022-A1 优先权日:2000-05-19 标题 :Inhibition of cell proliferation and matrix synthesis by antioxidants and NAD(P)H oxidase inhibitors 发明人:SHI YI; ZALEWSKI ANDREW 摘要:The present invention is directed to a method for the prophylactic and therapeutic treatment of diseases or disorders associated with the abnormal proliferation and extracellular matrix synthesis of smooth muscle cells (SMC) and fibroblasts due to activation of NAD(P)H and/or increased ROS generation. The method involves the administration of an NAD(P)H oxidase inhibitor(s) and/or antioxidant(s) to a mammal in an amount sufficient to treat the disease or disorder prophylactically or therapeutically. The NAD(P)H oxidase inhibitor inhibits the synthesis or translocation of NAD(P)H subunits, thereby blocking the generation of intracellular reactive oxygen species (ROS) and thus the proliferation and extracellular matrix synthesis of SMC and fibroblasts. Similarly, the administration of antioxidants blocks the generation of intracellular ROS, thereby inhibiting SMC and fibroblast proliferation and extracellular matrix synthesis. In addition to the prevention and treatment of vascular disease, such as atherosclerosis, graft disease, and restenosis, NAD(P)H oxidase inhibitors and antioxidants may be useful for the prevention and treatment of other conditions by decreasing cell proliferation and extracellular matrix synthesis associated therewith. These conditions include arthritis, keloid formation, cancer, tissue and organ fibrosis, and complications related to organ transplantation, metabolic syndrome, and radiation therapy.
