标题:Determination And Isolation Of A Thioesterase From Passion Fruit (Passiflora Edulis Sims) That Hydrolyzes Volatile Thioesters
摘要:Volatile Organosulfur Compounds (Voscs) Are High Impact Aroma Chemicals Characteristic Of Tropical Fruits Which Are Active As Both Free Thiols And The Respective Thioesters. Using A Simple And Sensitive Colorimetric Enzyme Assay,A Thioesterase Activity Toward Voscs Has Been Identified In Ripening Purple Passion Fruit (Passiflora Edulis Sims). The Assay Was Based On Determining The Release Of Free Thiols From 2-Methyl-3-Furanthiol Acetate Using Ellman'S Reagent. The Major Thioesterase In The Fruit Was Found To Be A Wall-Bound Protein In The Mesocarp. The Extracted Enzyme Activity Was Purified 150-Fold And Shown To Be Associated With A 43 Kda Monomeric Serine Hydrolase Which Was Selectively Labeled With A Fluorophosphonate Suicide Probe. Ms-Ms Sequencing Identified The Thioesterase As A Class 13 Glycoside Hydrolase,Most Similar To Pectin Acetylesterase,An Enzyme Involved In Cell Wall Modifications In The Peel Of A Number Of Fruit. Our Results Suggest That Cell Wall Hydrolases In Tropical Fruit May Have Additional Useful Roles In Biotransforming Voscs.

权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:A process for the direct synthesis of alkenylhalosilane monomers. Forming a slurry of liquid and copper-activated silicon from fresh silicon, cyclone fines and/or fine dust from silicon grinding, ultrafines and/or spent contact mass from the Direct Synthesis of alkylhalosilanes and arylhalosilanes, in a thermally stable solvent. Reacting the silanes by agitating the slurry with at least one unsaturated aliphatic or cycloaliphatic organohalide of the formula R1X, and optionally an organohalosilane and/or hydrogen halide, in the presence of a polymerization inhibiting Lewis base additive, at a reaction time, temperature and pressure effective to produce alkenylhalosilanes having the formulae, R1SiHX2, R12SiHX, R13SiX, R1SiX3, and R12SiX2 or mixtures thereof.

权利人:BRISTOL MYERS CO
摘要:Disclosed herein is a novel process using novel silyl enol ether intermediates of the formula 8 to generate novel azetidione thiolester intermediates of the formula 12 which can be used to form 1- beta -alkyl carbapenem antibiotics. It has now been discovered that if the R4 group is selected from a small group of moieties having the formula: an increased beta -yield of up to approximately 100% can be obtained.
