专利号:US-5231232-A 优先权日:1991-12-18 标题 :Method of preparing C-18 ketones used in the manufacture of Vitamins E and K 发明人:BABLER JAMES H 权利人:UNIV LOYOLA CHICAGO 摘要:Methods of forming unsaturated C-18 ketones which can be used in the synthesis of Vitamins E and K 1 are disclosed. One procedure involves coupling a C-9 primary allylic halide to a carbonyl-group-containing C-9 terminal alkyne. A second, two-step procedure employs a C-4 bis allylic halide (molar excess) and a carbonyl-group-containing C-9 terminal alkyne to form a C-13 primary allylic halide. The C-13 primary allylic halide can then be converted to the desired C-18 ketone by reaction with 2-methyl-3-butyn-2-ol. Novel C-18 ketones (e.g., 14-hydroxy-6,14-dimethyl-10-methylene-5-pentadecen-7,12-diyn-2-one), C-13 allylic halides (e.g., 10-chloromethyl-6-methyl-5,10-undecadien-7-yn-2-one) and C-9 allylic halides (e.g., 6-chloromethyl-2-methyl-6-hepten-3-yn-2-ol) are formed in the process.

专利号:US-2009111737-A1 优先权日:1999-05-24 标题:Novel antibacterial agents 发明人:CHRISTENSEN BURTON G; MORAN EDMUND J; GRIFFIN JOHN H; JUDICE J KEVIN; MU YONGQI; PACE JOHN L; MAMMEN MATHAI; AGGEN JAMES 权利人:CHRISTENSEN BURTON G; MORAN EDMUND J; GRIFFIN JOHN H; JUDICE J KEVIN; MU YONGQI; PACE JOHN L; MAMMEN MATHAI; AGGEN JAMES 摘要:This invention relates to novel multibinding compounds (agents) that are antibacterial agents. The multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands in their monovalent (i.e., unlinked) state have the ability to bind to a an enzyme involved in cell wall biosynthesis and metabolism, a precursor used in the synthesis of the bacterial cell wall and/or the bacterial cell surface thereby interfere with the synthesis and/or metabolism of the cell wall. In particular the multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands hasn a ligand domain capable of binding to penicillin binding proteins, a transpeptidase enzyme, a substrate of a transpeptidase enzyme, a beta-lactamase enzyme, pencillinase enzyme, cephalosporinase enzyme, a transglycoslase enzyme, or a transglycosylase enzyme substrate; Preferably, the ligands are selected from the beta lactam or glycopeptide class of antibacterial agents.

All of the molecules significantly inhibited growth of cultured normal human fibroblasts. The combination of an ROS-scavenging thiol group and a positively charged alkyl-amine backbone provided the most radioprotective aminothiol molecule.
