Lactones in the Synthesis of Prostaglandins and Prostaglandin Analogs [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
In the total stereo-controlled synthesis of natural prostaglandins (PGs) and their structural analogs, a vast class of compounds and drugs, known as the lactones, are encountered in a few key steps to build the final molecule, as: δ-lactones, γ-lactones, and 1,9-, 1,11-, and 1,15-macrolactones.

Effect of oleic acid supplementation on prostaglandin production in maternal endometrial and fetal allantochorion cells isolated from late gestation ewes [PDF]

open access: yes, 2015
Elevated circulating non-esterified fatty acids including oleic acid (OA) are associated with many pregnancy related complications. Prostaglandins (PGs) play crucial roles during parturition.

Diurnal rhythm of plasma EPA and DHA in healthy adults [PDF]

open access: yes, 2020
Knowledge of the diurnal variation in circulating omega-3 polyunsaturated fatty acids (n-3 PUFAs) may be an important consideration for the development of dosing protocols designed to optimise tissue delivery of these fatty acids.

Platelet-Activating Factor-Induced Reduction in Contact Hypersensitivity Responses Is Mediated by Mast Cells via Cyclooxygenase-2-Dependent Mechanisms [PDF]

open access: yes, 2018
Platelet-activating factor (PAF) stimulates numerous cell types via activation of the G protein-coupled PAF receptor (PAFR). PAFR activation not only induces acute proinflammatory responses, but it also induces delayed systemic immunosuppressive effects ...

Cytoprotection by prostaglandins.

open access: yesGastroenterology, 1979
Prostaglandins (PG) are a group of ZO-carbon oxy- genated fatty acids that are present in most mamma- lian cells and tissues. Approximately 20 of these chemicals have been identified in tissues and body fluids, whereas hundreds have been synthesized as analogs or derivatives of the natural PG.

Prostaglandins in Marine Organisms: A Review

open access: yesMarine Drugs, 2019
Prostaglandins (PGs) are lipid mediators belonging to the eicosanoid family. PGs were first discovered in mammals where they are key players in a great variety of physiological and pathological processes, for instance muscle and blood vessel tone ...

Consequences of altered eicosanoid patterns for nociceptive processing in mPGES-1-deficient mice [PDF]

open access: yes, 2007
Cyclooxygenase-2 (COX-2)-dependent prostaglandin (PG) E2 synthesis in the spinal cord plays a major role in the development of inflammatory hyperalgesia and allodynia. Microsomal PGE2 synthase-1 (mPGES-1) isomerizes COX-2-derived PGH2 to PGE2.

Temperature and time-dependent effects of delayed blood processing on oxylipin concentrations in human plasma. [PDF]

open access: yes, 2019
BACKGROUND:Oxidized derivatives of polyunsaturated fatty acids, collectively known as oxylipins, are labile bioactive mediators with diverse roles in human physiology and pathology.
