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.

Oxylipin metabolism in response to stress

Current Opinion in Plant Biology, 2002
Oxylipins comprise a group of biologically active compounds whose structural diversity is generated by the coordinate action of lipases, lipoxygenases, and a group of cytochromes P450 that are specialized for the metabolism of hydroperoxy fatty acids. Research on oxylipins has focused mainly on the biosynthesis of the plant signaling molecule jasmonic ...

The regulatory functions of oxylipins in fungi: A review

Journal of Basic Microbiology, 2023
AbstractQuorum sensing (QS) is a communication mechanism between microorganisms originally found in bacteria. In recent years, an important QS mechanism has been discovered in the field of fungi, namely, the lipoxygenase compound oxylipin of arachidonic acid acts as a QS molecule in life cycle control, particularly in the sexual and asexual development

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 ...

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 (

Biosynthesis and analysis of plant oxylipins

Free Radical Research, 2015
The term oxylipin is applied to the generation of oxygenated products of polyunsaturated fatty acids that can arise either through non-enzymatic or enzymatic processes generating a complex array of products, including alcohols, aldehydes, ketones, acids and hydrocarbon gases.

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.

Oxylipins and plant abiotic stress resistance

Biochemistry (Moscow), 2014
Oxylipins are signaling molecules formed enzymatically or spontaneously from unsaturated fatty acids in all aerobic organisms. Oxylipins regulate growth, development, and responses to environmental stimuli of organisms. The oxylipin biosynthesis pathway in plants includes a few parallel branches named after first enzyme of the corresponding branch as ...

Prostaglandins and oxylipins of corals

Russian Journal of Marine Biology, 2011
Literature data for the period from 1969 to 2010 on the distribution and chemical structures of prostaglandins, prostanoids, eicosanoids, and other cyclic and acyclic oxylipins from corals are summarized. The chemical structures of 97 compounds are given.
