[PMID: 37627584 PMCID: PMC10451816 DOI: 10.3390/antiox12081590] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 08/02/2023] [Accepted: 08/04/2023] [Indexed: 08/27/2023] Open
Abstract
Ferroptosis is a form of oxidative cell death that is characterized by enhanced lipid peroxidation and mitochondrial impairment. The enzymes acyl-CoA synthetase long-chain family member 4 (ACSL4) and lysophosphatidylcholine acyltransferase (LPCAT) play an essential role in the biosynthesis of polyunsaturated fatty acid (PUFA)-containing phospholipids, thereby providing the substrates for lipid peroxidation and promoting ferroptosis. To examine the impact of mitochondria in ACSL4/LPCAT2-driven ferroptosis, HEK293T cells overexpressing ACSL4 and LPCAT2 (OE) or empty vector controls (LV) were exposed to 1S, 3R-RSL3 (RSL3) for induction of ferroptosis. The ACSL4/LPCAT2 overexpression resulted in higher sensitivity against RSL3-induced cell death compared to LV-transfected controls. Moreover, mitochondrial parameters such as mitochondrial reactive oxygen species (ROS) formation, mitochondrial membrane potential, and mitochondrial respiration deteriorated in the OE cells, supporting the conclusion that mitochondria play a significant role in ACSL4/LPCAT2-driven ferroptosis. This was further confirmed through the protection of OE cells against RSL3-mediated cell death by the mitochondrial ROS scavenger mitoquinone (MitoQ), which exerted protection via antioxidative properties rather than through previously reported metabolic effects. Our findings implicate that mitochondrial ROS production and the accompanying organelle disintegration are essential for mediating oxidative cell death initiated through lipid peroxidation in ferroptosis.

Abstract
The present review article summarizes the synthesis of allenes, which bear an adjacent functional group, by [3,3]- or [2,3]-sigmatropic rearrangement of appropriate propargyl substrates. Functionalized allenes, such as allenyl isothiocyanates, isoelenocyanates, isocyanates, thiocyanates, azides, azo compounds and others, are easily available by these methods. In several cases, however, the title compounds show high reactivity, which leads to rapid intermolecular or intramolecular successive reactions. Consequently, synthesis of the allenes by sigmatropic rearrangement has to be combined with special techniques, for example, flash vacuum pyrolysis or in situ generation and trapping reactions. The high tendency of the presented functionalized allenes to undergo cyclization reactions can be utilized to prepare heterocyclic products, for instance, thiazoles, selenazoles, 1,2,3-triazoles and pyrazoles. The synthesis of functionalized 1,3-butadienes by a second sigmatropic rearrangement of the title compounds is also successful.

Elucidation of chemical modifier reactivity towards peptides and proteins and the analysis of specific fragmentation by matrix-assisted laser desorption/ionization collision-induced dissociation tandem mass spectrometry. RAPID COMMUNICATIONS IN MASS SPECTROMETRY : RCM 2019; 33 Suppl 1:40-49.

Abstract
RATIONALE Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) analysis of covalent 5-lipoxygenase inhibitors is challenging due to unknown amino acid specificity and low posttranslational modification (PTM)-identification rates. The analysis of the amino-acid specificity and of the characteristic fragmentation of chemically modified peptides is considered to improve knowledge for the analysis of chemically modified peptides and proteins by MALDI-MS. METHODS Various compounds were used to investigate the modification of synthetic peptides carrying reactive amino acid residues. Mass spectra were recorded using a MALDI-LTQ Orbitrap XL for high-resolution mass spectrometry and ion trap MALDI-MS2 . UV-Vis-based reduction and radical scavenging analysis was conducted. The on-plate digestion method described by Rühl et al was utilized for modification-site analysis at 5-lipoxygenase. RESULTS The analysis of amino-acid-specific reactivity revealed the reactivity of quinones towards cysteine residues and the potential occurrence of a subsequent oxidative process was observed by an UV-Vis-based reduction assay. MALDI collision-induced dissociation tandem mass spectrometry (CID-MS2 ) indicated a prominent fragmentation mechanism of modified cysteine and histidine residues. Fragmentation included highly abundant neutral-loss signals which could be used to identify new modifications induced by chemical modifiers at the cysteine-159 residue of 5-lipoxygenase. CONCLUSIONS Specificity and fragmentation analysis provides crucial information for the analysis of chemically modified cysteines and histidines by MALDI-MS. Elucidation of binding sites by MALDI-MS has been significantly improved using an easy-to-run peptide assay and gives background information for the analysis in the case of chemically modified 5-lipoxygenase.

Abstract
5-Lipoxygenase (5-LO) initiates the biosynthesis of pro-inflammatory leukotrienes from arachidonic acid, which requires the nuclear membrane-bound 5-LO-activating protein (FLAP) for substrate transfer. Here, we identified human 5-LO as a molecular target of melleolides from honey mushroom (Armillaria mellea). Melleolides inhibit 5-LO via an α,β-unsaturated aldehyde serving as Michael acceptor for surface cysteines at the substrate entrance that are revealed as molecular determinants for 5-LO activity. Experiments with 5-LO mutants, where select cysteines had been replaced by serine, indicated that the investigated melleolides suppress 5-LO product formation via two distinct modes of action: (1) by direct interference with 5-LO activity involving two or more of the cysteines 159, 300, 416, and 418, and (2) by preventing 5-LO/FLAP assemblies involving selectively Cys159 in 5-LO. Interestingly, replacement of Cys159 by serine prevented 5-LO/FLAP assemblies as well, implying Cys159 as determinant for 5-LO/FLAP complex formation at the nuclear membrane required for leukotriene biosynthesis.
