摘要:酵母torulopsis Gropengiesseri将长链烷烃转化为糖脂,其中糖脂掺入了烷烃的氧化衍生物.源自c 12-C 24的糖脂脂质成分的比较烷烃,各种氧化的烷烃衍生物以及一系列的β-烷氧基丙酸甲酯表明,烷烃代谢的主要途径涉及烷烃1-醇的形成,随后将其脱氢为相应的链烷酸.这些酸通过β-氧化或通过羟基化代谢以反应生成ω-羟基酸(随后是αω-二羧酸),并通过立体有择羟基化代谢成ω-1-羟基酸.通过结合到糖脂中,可以保护氧化的链烷酸免于进一步降解.链烷酸的链长决定(i)β-氧化或羟基化是主要反应,以及(II)羟基化主要发生在ω-或ω-1-位.当羟基化位点和羧基被14个亚甲基链隔开时,链烷酸的ω-和ω-1-羟基化效率最高.提出这些羟基化可以通过单一酶来实现.烷烃代谢的次要途径涉及形成烷烃-2-醇,其被掺入糖脂中而不被氧化代谢.长链烷-1-烯的发酵产生糖脂,其掺入衍生自烷-1-烯的ω-1-羟基

标 题 :Improvements in solid-phase synthesis of peptides and related compounds
发明人：ENGLEBRETSEN DARREN
权利人:UNIV QUEENSLAND; ENGLEBRETSEN DARREN
摘要:The invention relates to spacers for use in solid-phase synthesis of peptides and peptide-related compounds, in which a spacer construct is used to ensure that the target peptide or peptide-related compound is at a distance equivalent to at least 5-15 amino acids from the solid support. Constructs of the invention are particularly applicable to the synthesis of strongly hydrophobic peptide, which are otherwise difficult, if not impossible to purify and analyse. The constructs and methods of the invention are also applicable to synthesis of peptide nucleic acids.

权利人:COGNIS FRANCE SA
摘要:Disclosed is a method for enzymatic synthesis of esters of flavonoid and flavonoid derivatives, according to which a reaction medium containing an organic solvent, a glycosylated flavonoid or aglycon flavonoid, an acyl group donor, and an enzymatic catalyst is produced, b) additional quantities of flavonoid and/or acyl donor are optionally added during the reaction, and c) the obtained esters are separated from the enzymatic particles and the solvent. The inventive method is characterized by maintaining the concentration of water and/or alcohol which are formed during the reaction to below 150 mM. Advantageously, the molar ratio of flavonoid to acyl donor in the reaction medium is maintained in the range from 0.01 to 20.00 during the reaction.

发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

标 题:Enzyme catalyzed synthesis of polyesters
发明人：MORROW CARY J; WALLACE JOE S
权利人:UNIV NEW MEXICO
摘要:A method for synthesizing a polyester comprises reacting a diester and a dialcohol at approximately ambient temperature in the presence of an enzyme catalyst, preferably a lipase comprising porcine pancreatic lipase. The method is particularly adapted for enantioselective polymerization resulting in an optically active polyester. The polyesters preferably exhibit a weight average molecular weight, Mw, as measured by gel permeation chromatography of at least about 3000.
