标 题:Methods for the solid phase synthesis of combinatorial libraries of benzimidazoles benzoxazoles benzothiazoles and derivatives thereof
发明人：LABORDE EDGARDO; MATSUMOTO YUKIHARU
权利人:TELIK INC
摘要:The present invention provides an efficient and versatile method for the synthesis and screening of combinatorial libraries of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof. In order to expedite the synthesis of large arrays of compounds possessing these core structures, a general methodology for solid phase synthesis of these derivatives is provided. Arrays of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof useful as peptidomimetics and for the identification of agents having antifungal, antiviral, antimicrobial, anticoagulant, and antiulcer activity, or use in the treatment of inflammation, hypertension, cancer, and other conditions can be prepared by this method.

权利人:MAXYGEN INC; SELIFONOV SERGEY A; NEWMAN LISA M
摘要:This invention provides improved polypeptides, including dioxygenases, dehydrogenases, ligases and transferases that are useful for the biocatalytic synthesis of compounds such as α-hydroxycarboxylic acids, and aryl- and alkyl-hydroxy and carboxylic acid compounds. The polypeptides provided herein are improved in properties such as regioselectivity, enzymatic activity, stereospecificity, and the like. Methods for obtaining recombinant polynucleotides that encode these improved polypeptides are also provided, as are organisms that express the polypeptides and are thus useful for carrying out said biocatalytic syntheses. Also provided by the invention are methods for increasing said solvent resistance of organisms that are used in the synthetic methods.

权利人:DAUGULIS OLAFS; CHIONG HENDRICH; UNIV HOUSTON SYSTEM
摘要:A one-step method for efficiently converting carbon-hydrogen bonds into carbon-carbon bonds using chloroarenes and palladium catalysts is disclosed. This method allows faster introduction of complex molecular entities, a process that would otherwise require many more steps. This invention is particularly relevant for the organic synthesis of complex molecules such as, but not limited to, pharmacophores.

摘要:Provided is a method for quantitating a saccharide in a liquid sample. The method comprises incubating the liquid sample with 2,3-naphthalenediamine in the presence of iodine to allow a naphthimidazole group to be linked to the saccharide to obtain a first mixture; obtaining an 1 H-NMR spectrum of the first mixture; and comparing, in said 1 H-NMR spectrum, the intensity or integral of a proton signal corresponding to the saccharide to the intensity or integral of a proton signal corresponding to an internal standard present in the first mixture.
