Synthesis of an electrophilic keto-tetraene 15-oxo-Lipoxin A4 methyl ester via a MIDA boronate

A vasculo-protective circuit centered on lipoxin A4 and aspirin-triggered 15-epi-lipoxin A4 operative in murine microcirculation.

Endogenous protective pathways mitigate the overshooting of inflammation after sterile or infectious injury. Here we report that formyl peptide receptor 2 (Fpr2/3) null mice display a major phenotype with exacerbated vascular inflammation observed postischemia reperfusion (IR) injury of the mesenteric artery, characterized by marked neutrophil adhesion and extravasation as visualized by intravi...

Amnion Epithelial Cells Promote Lung Repair via Lipoxin A4

: Human amnion epithelial cells (hAECs) have been shown to possess potent immunomodulatory properties across a number of disease models. Recently, we reported that hAECs influence macrophage polarization and activity, and that this step was dependent on regulatory T cells. In this study, we aimed to assess the effects of hAEC-derived proresolution lipoxin-A4 (LXA4) on T-cell, macrophage, and ne...

Vinyl MIDA boronate: a readily accessible and highly versatile building block for small molecule synthesis

Iterative cross-coupling represents a potentially general approach for the simple, efficient, and flexible construction of natural products, pharmaceuticals, and materials. N-Methyliminodiacetic acid (MIDA) boronates represent a promising platform for the development of this type of synthesis strategy. This report describes the discovery that vinyl MIDA boronate (1) is an airand chromatographic...

Lipoxin A4: a novel anti-inflammatory molecule?

(1-bromovinyl)-MIDA boronate: a readily accessible and highly versatile building block for small molecule synthesis.

Iterative cross-coupling represents a potentially general approach for the simple, efficient, and flexible construction of a wide range of functional small molecules. In this context, (1-bromovinyl)-N-methyliminodiacetic acid (MIDA) boronate is a very useful building block for small molecule synthesis. This compound can serve as a starting material for the preparation of a wide range of 1,1-dis...
