29 04 20143 The Isoprostanes Pathways In the mid-1970s it was shown that PG-like compounds could be formed in vitro by the nonenzymatic peroxidation of purified PUFAs F 2-IsoPs have been discovered in 1990 by Milne et al [] and Roberts II and Morrow [] and since then they collected a lot of evidence that these compounds might be biomarkers of lipid peroxidation and oxidative stress in vivo

In recent years scientific evidence supporting the relationship between diet and health has emerged This has led to a growing interest in full and healthy food habits in which fruits and vegetables are abundant (particularly in the Mediterranean diet) and act as sources of natural antioxidants as well as play major roles in preventing certain diseases It is estimated that 80% of

Isoprostanes and Asthma

Isoprostanes are prostaglandin (PG)-like compounds generated in vivo following oxidative stress by non-enzymatic peroxidation of polyunsaturated fatty acids including arachidonic acid They are named based on their prostane ring structure and by the localization of hydroxyl groups on the carbon side chain these structural differences result in a broad array of isoprostane molecules with

GUEST ARTICLE

The isoprostanes can be generated from different PUFAs for example arachidonic acid (AA) generates 64 isomers of F 2-isoprostanes (F 2-IsoPs) [3] EPA generates 192 isomers of F 3-isoprostanes (F 3-IsoPs) and DHA generates 256 iso-mers of neuroprostanes (NeuroPs) [4 5] We will focus on F 3-IsoPs and F 4-NeuroPs in this review

Total Synthesis of Isoprostanes Derived from Adrenic Acid

Of special interest are the F 2 ‐dihomo‐isoprostanes because they could represent potential biomarkers for myelin damage as its main PUFA constituent is adrenic acid Our strategy based on a pivotal enantiomerically enriched intermediate has allowed access to F 2 ‐dihomo‐IsoP and both C5 epimers of 5‐F 3t ‐IsoP for the first time

Isoprostane

The isoprostanes are prostaglandin-like compounds formed in vivo from the free radical-catalyzed peroxidation of essential fatty acids (primarily arachidonic acid) without the direct action of cyclooxygenase (COX) enzymes The compounds were discovered in 1990 by L Jackson Roberts and Jason D Morrow in the Division of Clinical Pharmacology at Vanderbilt University

Pathophysiology of isoprostanes in the cardiovascular

Furthermore the reduction of endoperoxide intermediates from docosahexanoic acid leads to the formation of so‐called neuroprostanes in the nervous system (Roberts et al 1998) In general isoprostanes are formed by two routes of lipid peroxidation consisting of the endoperoxide and the dioxetane/endoperoxide mechanism

Accumulating data shows that oxidative stress plays a crucial role in neurodegenerative disorders The literature data indicate that in vivo or postmortem cerebrospinal fluid and brain tissue levels of F 2 -isoprostanes (F 2 -IsoPs) especially F 4 -neuroprotanes (F 4 -NPs) are significantly increased in some neurodegenerative diseases: multiple sclerosis Alzheimer's disease Huntington's

Lipid peroxidation biomarkers for evaluating oxidative

Hypothesis: Because α-TOH deficiency is associated with increased lipid peroxidation it was hypothesized that F 2-isoprostanes (F 2 IsoP) F 4-neuroprostanes (F 4 NP) and oxysterols derived from free radical oxidation would be increased in the cerebrospinal fluid (CSF) and neural tissue of eNAD/EDM affected horses and could serve as potential biomarkers for disease Animals:
