标题:Unequivocal Identification Of Compounds Formed In The Photodegradation Of Fenitrothion In Water/methanol And Proposal Of Selected Transformation Pathways
摘要:The Photodegradation Of Fenitrothion Was Examined In A Mixture Of Distilled Water/methanol (5:1),The Uv Irradiation Was Carried Out With A High-Pressure Hg Lamp During 7 H. For The Identification Of Further Breakdown Products,Fenitrooxon And Carboxyfenitrothion Were Also Irradiated Under Experimental Conditions Identical To Those For Fenitrothion. The Identification Of The Breakdown Products Formed Was Carried Out By Gas Chromatography-Mass Spectrometry (Gc-Ms) With Electron Impact (Ei) And Comparison With Authentic Standards Synthesized In The Laboratory. A Total Of 21 Photoproducts Of Oxidation,Isomerization,Denitration,And Solvolysis That May Be Of Concern In Environmental Studies Were Unequivocally Identified. Among Them Were Formyldenitrofenitrothion,Carbomethoxydenitro-Fenitrooxon,And Hydroxymethyldenitrofenitrooxon. A Proposed Mechanism Of The Process Is Presented. Selected Pathways For The Photodegradation Of Fenitrothion Were Examined: (I) Degradation Through Hydrolysis,With Eventual Remethylation; (II) P=s To P=o Oxidation; (III) Denitration; And (Iv) Oxidation Of The Methyl Substituent Through Hydroxymethyl And Formyl To Give The Corresponding Carboxy Derivatives.

标题 :Process for solid phase glycopeptide synthesis
发明人：WONG CHI-HUEY; SCHUSTER MATTHIAS
权利人:SCRIPPS RESEARCH INST
摘要:A process for the synthesis of a glycopeptide using a solid phase matrix is disclosed. The matrix is compatible with aqueous and organic solvents and is comprised of a silica-based solid support to which is linked a two-part spacer group having a chain length of about 12 to about 40 methylene groups. The first part of the spacer is covalently bonded to the silica-based support and has a length of about 3 to about 10 methylene groups. The second spacer part is covalently bonded to the first part of the spacer and comprises the distal end of the two part spacer. The second part is soluble as a free molecule in each of water, dimethylformamide and dichloromethane and has a terminal amine or hydroxyl group to which the C-terminal residue of the peptide portion of the glycopeptide chain is bonded. The chain of atoms connecting the desired glycopeptide to the solid phase matrix also includes a moiety having a selectively severable bond which on cleavage of that bond separates the matrix from whatever else is bonded to that moiety.

标 题:Pesticidal activity of functionalized alkenes
发明人：LINDERMAN RUSSELL J
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides non-peptide organic compounds that have a structure analogous to or reminiscent of the TMOF structure and have pesticidal activity. Thus the present invention concerns pesticidal compounds that inhibit digestion in pests by terminating or otherwise blocking synthesis of digestive enzymes by activating a TMOF receptor (collectively referred to herein as “pesticidal compoundsâ€?). The pesticidal compounds and other compounds of the present invention are usefully employed in the control of pests, particularly insect pests such as mosquitoes, which ingest blood.

标 题:Production of fucosylated carbohydrates by enzymatic fucosylation synthesis of sugar nucleotides; and in situ regeneration of GDP-fucose
发明人：WONG CHI-HUEY; ICHIKAWA YOSHITAKA; SHEN GWO-JENN; LIU KUN-CHIN
权利人:SCRIPPS RES INSITUTE
摘要:This invention contemplates improved methods of enzymatic production of carbohydrates especially fucosylated carbohydrates. Improved syntheses of glycosyl 1- or 2-phosphates using both chemical and enzymatic means are also contemplated. The phosphorylated glycosides are then used to produce sugar nucleotides that are in turn used as donor sugars for glycosylation of acceptor carbohydrates. Especially preferred herein is the use of a disclosed method for fucosylation.
