Oxylipin analysis methods

The Plant Journal, 2006
SummaryPractical guidelines for monitoring and measuring compounds such as jasmonates, ketols, ketodi(tri)enes and hydroxy‐fatty acids as well as detecting the presence of novel oxylipins are presented. Additionally, a protocol for the penetrant analysis of non‐enzymatic lipid oxidation is described. Each of the methods, which employ gas chromatography/

Role of oxylipins in cardiovascular diseases [PDF]

Acta Pharmacologica Sinica, 2018
Globally, cardiovascular diseases (CVDs) are the number one cause of mortality. Approximately 18 million people died from CVDs in 2015, representing more than 30% of all global deaths. New diagnostic tools and therapies are eagerly required to decrease the prevalence of CVDs related to mortality and/or risk factors leading to CVDs.

Oxylipins and oxylipin synthesis pathways in fungi

Applied Biochemistry and Microbiology, 2017
Oxylipins are a family of oxygenated fatty acids that are very diverse with regard to origin, structure, and functions. These compounds are found in almost all living beings and serve both as autoregulators of the development of organisms and as communication molecules.

Regulation of oxylipin synthesis

Biochemical Society Transactions, 2000
Two very common groups of oxylipins formed in plants involve the conversion of fatty acid hydroperoxides, such as hydroperoxy-octadecatrienoic acid, into further metabolites by allene oxide synthase and hydroperoxide lyase. Both of these oxylipin branch pathways appear to be ubiquitous or nearly so in plants, but the relative activities of these two ...

Oxylipins from Dracontium loretense

Journal of Natural Products, 2009
Four novel oxylipins (1-4) were isolated from the n-butanol extract of the corms of Dracontium loretense. Their structures were assigned by 1D and 2D NMR analyses and electrospray ionization multistage ion trap mass spectrometry (ESI-ITMS(n)) data. Relative configurations were assigned on the basis of combined analysis of homonuclear and heteronuclear (

Brominated Oxylipins and Oxylipin Glycosides from Red Sea Corals

European Journal of Organic Chemistry, 2002
AbstractEight new brominated oxylipins 1−8, including two glycosides, were isolated from the Red Sea invertebrates Dendrophyllia sp., Dendronephthya sp. (red variety), Dendronephthya sp. (yellow variety), and Tubipora musica. Their structures were elucidated mainly on the basis of NMR spectroscopic data.

Targeting esterified oxylipins by LC–MS - Effect of sample preparation on oxylipin pattern

Prostaglandins & Other Lipid Mediators, 2020
A major part of oxygenated metabolites of polyunsaturated fatty acids - i.e. eicosanoids and other oxylipins - in biological samples is found in the esterified form. Yet, their biological role is only poorly understood. For quantification of esterified oxylipins in biological samples current protocols mostly apply alkaline hydrolysis with or without ...

Oxylipin patterns in human colon adenomas

Prostaglandins, Leukotrienes and Essential Fatty Acids, 2021
Cyclooxygenase (COX)-derived prostaglandin E2 (PGE2) is an important lipid mediator in colorectal carcinoma (CRC) pathogenesis. Other lipid mediators derived from lipoxygenases (LOX) have also been implicated in neoplastic processes in the colon. In this study we aimed to characterize lipid mediators, so called oxylipins, in human colon adenomatous ...

Oxylipin covered ascospores of Eremothecium coryli

Antonie van Leeuwenhoek, 2005
Eremothecium coryli is known to produce intriguing spindle-shaped ascospores with long and thin whip-like appendages. Here, ultra structural studies using scanning electron microscopy, indicate that these appendages serve to coil around themselves and around ascospores causing spore aggregation.

Oxylipin vanillyl acetals from Solanum lyratum

Fitoterapia, 2020
Four undescribed oxylipin vanillyl acetals with four stereogenic carbons were isolated from the herbs of Solanum lyratum. A comprehensive set of spectroscopic methods were used to elucidate the structures and relative configurations of 1-4. The absolute configurations of the naturally occurring compounds are assigned as 7S, 9'S, 10'S, 11'R at the site ...
