    Lipid X

    		Bacterial Cardiovascular Disease Inflammation/Immunology
    Lipid X is a 2,3-diacylglucosamine-1-phosphate that serves as the monosaccharide precursor of lipid A, possessing both LPS antagonist and weak agonist activities. Lipid X exerts protective effects by inhibiting tumor necrosis factor production, monocyte procoagulant activity, and neutrophil priming. Lipid X may induce transient pulmonary hypertension, neutropenia, and mild pyrogenic effects in laboratory animals. Lipid X has low toxicity and no in vitro antibacterial activity, but it significantly reduces mortality following Gram-negative bacterial infection and endotoxin exposure. Lipid X tends to accumulate in liver tissue, binds to circulating cellular components, and can be converted to lipid Y through transesterification. Lipid X can be used in research on Gram-negative bacterial sepsis, endotoxemia, and associated pulmonary hypertension .

    4-OHE

    (E)-4-Oxo-2-hexenal

    		 Bacterial Apoptosis Infection
    4-OHE ((E)-4-Oxo-2-hexenal) is a mutagen formed by omega-3 lipid peroxidation. 4-OHE reacts with deoxyguanosine, deoxycytidine and 5-methyldeoxycytidine to form covalent adducts. 4-OHE induces apoptosis and exhibits genotoxicity. 4-OHE inhibits the growth of Gram-positive and Gram-negative bacteria, which correlates with its electrophilic reactivity towards nucleophilic biomolecules. 4-OHE is a chemical defense component of Dolycoris baccarum (sloe bug), and acts as a deterrent and toxin against insect predators .

    Temporin SHF

    		Bacterial Infection
    Temporin SHF is a broad-spectrum antimicrobial peptide that is active against Gram-positive and Gram-negative bacteria and yeasts, but does not have hemolytic activity. Temporin SHF disrupts the acyl chain stacking of anionic lipid bilayers, leading to cracks and disintegration of microbial membranes. Temporin SHF can be used in the development of antimicrobial drugs .

    L-4-Aminoarabinose-bactoprenyl phosphate

    L-4-Aminoarabinose-BP

    		 Endogenous Metabolite Infection
    L-4-Aminoarabinose-bactoprenyl phosphate (L-4-Aminoarabinose-BP) is a substrate of the ArnT enzyme and participates in lipid A modification through covalent bonding. L-4-Aminoarabinose-bactoprenyl phosphate transfers L-4-aminoarabinose (Ara4N) to the lipid A portion of lipopolysaccharide (LPS), mediating cationic modification of lipid A, thereby conferring resistance to cationic antimicrobial peptides (CAMPs) in Gram-negative bacteria. L-4-Aminoarabinose-bactoprenyl phosphate is an endogenous intermediate synthesized in vivo by a series of enzymes such as ArnC and ArnD encoded by the arn operon in Gram-negative bacteria such as Escherichia coli .
