标题 :Method for fully automated synthesis of 16β-18F-fluoro-5α-dihydrotestosterone (18F-FDHT)
发明人：MURPHY JENNIFER MARIE; LAZARI MARK SAUL

摘要:The automated synthesis of clinically relevant amounts of 16β- 18 F-fluoro-5α-dihydrotestosterone ( 18 F-FDHT) using a commercially available radiosynthesizer. Synthesis was performed in 90 minutes with a decay-corrected radiochemical yield of 29±5%. The specific activity was 4.6 Ci/μmol (170 GBq/μmol) at end of formulation with a starting activity of 1.0 Ci (37 GBq). The formulated 18 F-FDHT yielded sufficient activity for multiple patient doses and passed all quality control tests required for routine clinical use.

权利人:UNIV TALCA
摘要:Described herein is a new asymmetric synthesis of imines to obtain β-carboline derivatives useful as key intermediate compounds for the synthesis of phosphodiesterase inhibitors using a new process with palladium or ruthenium hydride and/or nickel boride to reduce chiral intermediates. The use of chloroformate chiral auxiliaries is further described for the reduction and asymmetric hydrogenation of imines to obtain β-carboline derivatives and intermediate compounds used in the preparation thereof.

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

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.
