Hepoxilins(HXs)和trioxilins(TrXs)是脂质介质,可调节人体中痕量的多种生理过程。它们已经通过化学方法合成,其具有诸如低产率,副产物形成和使用有毒化学试剂的缺点。在这里,我们报告了由重组大肠杆菌合成的十种类型的HX和TrX的鉴定使用五个多不饱和脂肪酸(PUFA)来表达细菌花生四烯酸15-脂加氧酶和/或环氧化物水解酶。其中,有八种是新的。该发现是由于具有高活性的微生物酶具有与人类酶相同的催化活性。我们成功地将PUFA通过细胞高效,经济,环保地生物转化为9种HX和TrX,从而产生了大于10 g L -1的14,15-HXB 3和13,14,15-TrXB 3,转化率> 70%。我们的研究有助于医学上重要的脂质介体的环境友好合成。

hydroxyeicosapentaenoic acid families) were derivatized with 4-I-AMPP+ and subjected to a reversed-phase liquid chromatography workflow that afforded chromatographic resolution of isomers in conjunction with structurally diagnostic PD mass spectra. CONCLUSIONS PD of these complex HFAs was found to be sensitive to the locations of hydroxyl groups and carbon-carbon double bonds, which are structural properties strongly

The present invention relates to the use of endogenous reference metabolites and a method for normalization of intensity data corresponding to amounts and/or concentrations of selected target metabolites in a biological sample of a mammalian subject, wherein said intensity data are obtained by a metabolomics analysis method with one or a plurality of endogenous reference metabolites, comprising carrying out at least one in vitro metabolomics analysis method of said selected target metabolites in said biological sample, simultaneously carrying out in the same sample a quantitative analysis of one or a plurality of endogenous reference metabolites or derivatives thereof, wherein said endogenous reference metabolites are such compounds in the biological sample which are present in the subject at an essentially constant level; and wherein said endogenous reference metabolites or derivatives thereof have a molecular mass less than 1500 Da.
The present invention relates to a reliable and statistically significant method for predicting the likelihood of an onset of an inflammation associated organ failure from a biological sample of a mammalian subject in vitro, by means of a subject's quantitative metabolomics profile comprising a plurality of endogenous metabolites, and comparing it with a quantitative reference metabolomics profile of a plurality of endogenous organ failure predictive target metabolites in order to predict whether the subject is likely or unlikely to develop an organ failure. Furthermore, the invention relates to the usefulness of endogenous organ failure predictive target metabolites in such a method, and finally, the present invention relates to a Kit for carrying out said method.

The present invention relates to a method for diagnosing multiple sclerosis (MS) in a subject suspected to suffer therefrom comprising the steps of: a) determining the amounts of at least three markers from a group of markers comprising LPA20.4, HETE15S (15-hydroxyeicosatetranoic acid), GluCerC16, LacCerC24.1, C16Sphinganine, biopterin, PEA (palmitoylethanolamine) and OEA (oleoylethanolamide) in a sample of said subject; b) comparing the determined amounts to a reference or to references; and c) diagnosing MS based on said comparison in said subject.
本发明涉及一种诊断疑似多发性硬化症(MS)患者的方法,该方法包括以下步骤:a) 从一组标记物中确定至少三种标记物的含量,这组标记物包括 LPA20.4、HETE15S(15-羟基苦杏仁酸)、GluCerC16、LacCerC24.1、C16Sphinganine、生物蝶呤、PEA(棕榈酰乙醇胺)和 OEA(油酰乙醇酰胺)组成的一组标记物;b)将确定的量与参照物或参考物进行比较;以及 c)根据所述比较结果对所述受试者进行 MS 诊断。
