4 oxo 2 nonenal

4-hydroxy Nonenal is a lipid peroxidation product derived from oxidized ω-6 polyunsaturated fatty acids such as arachidonic acid and linoleic acid. [1] [2] It exhibits various biological activities such as cytotoxicity, growth inhibiting activity, genotoxicity, and chemotactic activity and has been widely used as a marker of lipid peroxidation.[1][2][3] 4-oxo-2-Nonenal is a more recently identified product of lipid peroxidation.[4][5][6] It actively modifies histidine and lysine residues on proteins and causes protein cross-linking. [7][8] 4-oxo-2-Nonenal also modifies 2’-deoxyguanosine, further implicating lipid peroxidation in mutagenesis and carcinogenesis.[4]

4-Oxo-2-nonanal (4-ONE) is a lipid peroxidation product that actively modifies histidine and lysine residues in proteins, leading to protein cross-linking, and alters 2'-deoxyguanosine, indicating its role in mutagenesis and carcinogenesis. 4-ONE alkyne, an alkyne-tagged electrophile, serves as a probe for isolating and identifying lipid peroxidation reaction products through click chemistry.
