Isotope-Labeled Hydroxy Fatty Acids

Lipoxin A4-d₅ is the deuterium labeled Lipoxin A4. Lipoxin A4 (LXA4), an endogenous lipoxygenase-derived eicosanoid mediator, has potent dual pro-resolving and anti-inflammatory properties. Lipoxin A4 inhibits proliferation and inflammatory cytokine/chemokine production of human epidermal keratinocytes (NHEKs) associated with the ERK1/2 and NF-kB pathways. Lipoxin A4 inhibits serum amyloid A (SAA)-mediated IL-8 release with an IC₅₀ value of 25.74 nM.

12(S)-HETE-d8 contains eight deuterium atoms at the 5, 6, 8, 9, 11, 12, 14 and 15 positions. 12(S)-HETE-d8 is intended for use as an internal standard for the quantification of 12(S)-HETE by GC- or LC-mass spectrometry (MS). 12(S)-HETE-d8 is the predominant lipoxygenase product of mammalian platelets. It enhances tumor cell adhesion to endothelial cells, fibronectin, and the subendothelial matrix at 0.1 µM.

Thromboxane B2-D4 is the deuterium labeled Thromboxane B2. Thromboxane B2 is a prostaglandin derivative that is released during anaphylaxis. Thromboxane B2 induces arterial contraction and platelet aggregation.

11-Dehydro-thromboxane B2-d₄ is the d₄-labeled 11-Dehydro-thromboxane B2 (HY-113420). 11-Dehydro-thromboxane B2 is a stable terminal metabolite of thromboxane A2 and an agonist of the CRTH2 receptor. 11-Dehydro-TXB2 activates human eosinophils, basophils, and CRTH2-transfected BaF/3 cells through a pertussis toxin-insensitive G protein-PLC pathway, inducing intracellular calcium mobilization, morphological changes, and chemotaxis, but does not affect platelet aggregation. 11-Dehydro-thromboxane B2 is involved in thrombosis and promotes eosinophil recruitment to the lungs in allergic inflammation, and its urinary levels are used to assess the inhibitory effect of Aspirin (HY-14654) on thromboxane production. 11-Dehydro-TXB2 serves as a biomarker for research related to asthma, atopic rhinitis, nephropathy, and coronary artery disease.

9-HETE-d₈ ((±)9-HETE-d₈) is the deuterium labeled 9-HETE (HY-113943A).

Thromboxane B2-d₉ is deuterium labeled Thromboxane B2. Thromboxane B2 is a prostaglandin derivative that is released during anaphylaxis. Thromboxane B2 induces arterial contraction and platelet aggregation.

11-Dehydro-thromboxane B2-¹³C₅ is the ¹³C-labeled 11-Dehydro-thromboxane B2 (HY-113420). 11-Dehydro-thromboxane B2 is a stable terminal metabolite of thromboxane A2 and an agonist of the CRTH2 receptor. 11-Dehydro-TXB2 activates human eosinophils, basophils, and CRTH2-transfected BaF/3 cells through a pertussis toxin-insensitive G protein-PLC pathway, inducing intracellular calcium mobilization, morphological changes, and chemotaxis, but does not affect platelet aggregation. 11-Dehydro-thromboxane B2 is involved in thrombosis and promotes eosinophil recruitment to the lungs in allergic inflammation, and its urinary levels are used to assess the inhibitory effect of Aspirin (HY-14654) on thromboxane production. 11-Dehydro-TXB2 serves as a biomarker for research related to asthma, atopic rhinitis, nephropathy, and coronary artery disease.

Oleic acid-d₃₄ (9-cis-Octadecenoic acid-d₃₄) is the deuterium labeled Oleic acid (HY-N1446). Oleic acid (9-cis-Octadecenoic acid) is an abundant monounsaturated fatty acid. Oleic acid is a Na⁺/K⁺ ATPase activator.

2-Hydroxyhexanoic acid-d₃ is the d₃ labeled 2-Hydroxyhexanoic acid (HY-75954). 2-Hydroxyhexanoic acid is a metabolite. 2-Hydroxyhexanoic acid is elevated in metastatic pancreatic neuroendocrine tumors. 2-Hydroxyhexanoic acid does not promote the proliferation, migration or invasion of pancreatic neuroendocrine tumor cells. 2-Hydroxyhexanoic acid can be used in the research of metastatic pancreatic neuroendocrine tumors.

Propionyl CoA-d₅ is the deuterium labeled Propionyl CoA (HY-141467). Propionyl CoA serves as a common intermediate in the catabolic pathways of 1,2-propanediol and propionate in Salmonella enterica serovar Typhimurium LT2, and also functions as a precursor for 2-methylcitrate. Propionyl CoA is utilized as a substrate for the 2-methylcitrate synthase (PrpC) enzyme to synthesize 2-methylcitrate.

9(S)-HODE-¹³C₁₈ ((+)-α-Dimophecolic acid-¹³C₁₈) is ¹³C labeled 9S-HODE. 9S-HODE (Alpha-dimorphecolic acid) is an octadecadienoic acid and the main active derivative of linoleic acid, which can reduce the viability of HL-60 cells and induce apoptosis. 9S-HODE is rich in lipid peroxidation (LPO) products and is almost an ideal marker for LPO.

Palmitoyl serinol-d₅ is the deuterium labeled Palmitoyl serinol. Palmitoyl serinol (N-Palmitoyl serinol) is an analog of the endocannabinoid N-palmitoyl ethanolamine (PEA). Palmitoyl serinol improves the epidermal permeability barrier in both normal and inflamed skin.
