标题 :Solid phase synthesis method and reagent
发明人：SWANSON MELVIN J
权利人:SURMODICS INC
摘要:A reagent composition adapted to be coated onto a support surface in order to provide that surface with a high density of reactive groups. The surface, thus coated, can be used for any suitable purpose, and is particularly well suited for use as a solid phase synthesis support surface. The synthesis support surface, in turn, can be used in repetitive and combinatorial syntheses such as the synthesis of polynucleotides, polypeptides and polysaccharides. The polymeric coating can be used to provide increased effective surface area, particularly in situations in which the effective area of the support surface is itself limited, as on the surface of a silicon wafer. In so doing, the polymeric coating provides an optimal combination of such properties as reactive density and surface area or volume.

摘要:Severely sterically hindered secondary aminoether alcohols are prepared by reacting organic carboxylic, organic carboxylic acid halides, acid anhydrides or a ketene with an alkyl, alkaryl or alkylhalo sulfonate to yield a sulfonic-carboxylic anhydride compound which is then reacted with a dioxane to cleave the ring of the dioxane, yielding a cleavage product which cleavage product is then aminated with an alkylamine and hydrolyzed with base to yield the severely sterically hindered secondary aminoether alcohol.

摘要:The present invention relates to substrates comprising a crosslinked network of covalently attached antimicrobial and/or antibiofouling polymers. The crosslinked network of antimicrobial and/or antibiofouling polymers acts highly efficiently against pathogens, e.g. bacteria and fungi. Both the antimicrobial and the antibiofouling cross-linked polymer networks are preferably better resistant to mechanical damage than simple surface-immobilized polymer monolayers. The antimicrobial and/or antibiofouling polymers of the crosslinked network are preferably obtained by ring opening metathesis polymerization (ROMP) and exhibit a molecular weight of preferably more than 30,000 or even 100,000 g mol−1. The crosslinked network of antimicrobial and/or antibiofouling polymers is preferably covalently attached to the surface of a substrate, e.g. an implant, a medical device, medical equipment or a (tissue-supporting) biomaterial, etc. The present invention is also directed to uses of crosslinked networks of antimicrobial and/or antibiofouling polymers as defined herein, e.g. for coating a surface of a substrate, and to methods therefore.

权利人:PFIZER
摘要:Carbapenam-3-carboxylic acids and carbapen-2-em-3-carboxylic acids substituted at the 1-position with an oxo, a hydroxy or an acetoxy group, variously substituted at the 2-position with such groups as methyl, acetoxymethyl, methanesulfonyloxy, alkoxy, alkylthio, aminoalkylthio or amidinoalkylthio and optionally substituted at the 6-position with a hydroxyalkyl group, an acetoxyalkyl group or a conventional penicillin side-chain, pharmaceutically-acceptable salts thereof and various esters thereof wherein the esterifying group is selectively removed in the laboratory, or hydrolyzed under physiological conditions. n These compounds are useful either systemically or topically in the treatment of diseases caused by susceptible microorganisms, as animal feed additives for promotion of growth, or in the preservation of biodegradable materials, or as intermediates to compounds having such antibacterial activity. n Key to the synthesis of these compounds is the light catalyzed rearrangement of 2-diazo-1-oxoceph-3-em-4-carboxylates to 1-oxocarbapen-2-em-3-carboxylates, a newly discovered reaction determined to be of general applicability.

标 题:Process for producing diphenylethers and esters
发明人：LOURENS GERHARDUS JOHANNES
权利人:DOW CHEMICAL CO
摘要:An improved synthesis of diphenylethers, and in particular, the bacteriostat 2,4,4'-trichloro-2'-hydroxydiphenylether, is described wherein 2'-acetyl-2,4,4'-trichlorodiphenylether is oxidised under Baeyer-Villiger conditions to produce 2'-acetoxy-2,4,4'-trichlorodiphenylether in near quantitative yield. Best oxidative conditions include the use of anhydrous permaleic acid produced in situ. The ester is purified readily by simple recrystallization, as no dibenzofurans and only minor amounts of byproducts are formed in the process. The ester is converted into the desired halogenated phenolic diphenylether, 2,4,4'-trichloro-2'-hydroxydiphenylether, by hydrolysis or transesterification. The final product is purified to a high degree by vacuum distillation and crystallization to meet current purity standards for approved applications.
