biotinpeg4alkyne

4-hydroxy Nonenal (4-HNE) is a major aldehyde produced during the lipid peroxidation of ω-6 polyunsaturated fatty acids, such as arachidonic acid and linoleic acid. It is considered a potential causal agent in numerous diseases, including chronic inflammation, neurodegenerative diseases, atherosclerosis, diabetes, and cancer, in part because it covalently modifies DNA and proteins resulting in genetic mutations and altered cell signaling, respectively. 4-HNE Alkyne is a form of 4-HNE with a terminal alkyne. Such terminal alkyne groups can be used in linking reactions, known as click chemistry, characterized by high dependability and specificity of azide-alkyne bioconjugation reactions. Click chemistry has only recently been applied to the study of oxidized lipids.

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.

Dde Biotin-PEG4-alkyne is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.

Biotin-PEG4-alkyne is a biotin-labeled, PEG-based PROTAC linker used in PROTAC synthesis.
