Abstract
This review article assembles key recent advances in the synthetic chemistry and biology of specialised pro-resolving mediators (SPMs). The major medicinal chemistry developments in the design, synthesis and biological evaluation of synthetic SPM analogues of lipoxins and resolvins have been discussed. These include variations in the top and bottom chains, as well as changes to the triene core, of lipoxins, all changes intended to enhance the metabolic stability whilst retaining or improving biological activity. Similar chemical modifications of resolvins are also discussed. The biological evaluation of these synthetic SPMs is also described in some detail. Original investigations into the biological activity of endogenous SPMs led to the pairing of these ligands with the FPR2/LX receptor, and these results have been challenged in more recent work, leading to conflicting results and views, which are again discussed.

Abstract
Objective Synthesis of novel aromatic Lipoxin A4 lactone analogues. Results Novel para-substituted aromatic lactone analogues of Lipoxin A4 have been synthesized in a convergent manner with six steps in the longest linear sequence in 12–13% yields, employing 2-deoxy-d-ribose as a chiral pool starting material and the classical E-selective Wittig olefination. Supplementary Information The online version contains supplementary material available at 10.1186/s13104-022-05917-4.

Abstract
![]()
Failure to resolve
inflammation underlies many prevalent pathologies.
Recent insights have identified lipid mediators, typified by lipoxins
(LXs), as drivers of inflammation resolution, suggesting potential
therapeutic benefit. We report the asymmetric preparation of novel
quinoxaline-containing synthetic-LXA4-mimetics (QNX-sLXms).
Eight novel compounds were screened for their impact on inflammatory
responses. Structure–activity relationship (SAR) studies showed
that (R)-6 (also referred to as AT-02-CT)
was the most efficacious and potent anti-inflammatory compound of
those tested. (R)-6 significantly attenuated
lipopolysaccharide (LPS)- and tumor-necrosis-factor-α (TNF-α)-induced
NF-κB activity in monocytes and vascular smooth muscle cells.
The molecular target of (R)-6 was investigated.
(R)-6 activated the endogenous LX receptor
formyl peptide receptor 2 (ALX/FPR2). The anti-inflammatory properties
of (R)-6 were further investigated in vivo in murine models of acute inflammation. Consistent
with in vitro observations, (R)-6 attenuated inflammatory responses. These results support
the therapeutic potential of the lead QNX-sLXm (R)-6 in the context of novel inflammatory regulators.
