Acetylene-PEG5-acid Chemical Properties,Uses,Production
Description
Propargyl-PEG5-acid has a propargyl group at one end and an acid group at the other end. The acid can react with primary amines to form a stable amide bond, activation will be needed. The PEG units enhances solubility of the molecule in aqueous environment. The propargyl group can be linked to azide-containing biomolecules via Click Chemistry.
Uses
Propargyl-peg5 Acid is used as a reactant in the preparation of site-specific antibody-pyrrolobenzodiazepine conjugates.
Uses
Alkyne-PEG5-acid may be used in the synthesis of peptide nucleic acid (PNA) oligomers that can conjugate with vitamin B12 via Cu-catalyzed 1,3-dipolar cycloaddition in order to study if vitamin B12 to transport PNA oligonucleotides into bacterial cells.
reaction suitability
reaction type: click chemistry
reagent type: cross-linking reagent
IC 50
Non-cleavable Linker; PEGs
