High-purity (S, R, S)-AHPC-PEG4-tosyl from Axispharm is a PROTAC linker that combines an E3 ligase ligand with a PEG4 linker, the tosyl group is reacted with an amine or other nucleophile to Enhancing PROTAC drug research and discovery. The PEG4 spacer increases the hydrophilicity of the compound.
(S,R,S)-AHPC-PEG4-tosyl is an amino acid-based polymer, consisting of an amino acid called AHPC (N-acetyl-L-homoserine lactone) attached to a four-arm polyethylene glycol (PEG) backbone, with a tosyl group (a sulfur-containing phenyl group) at the end of each arm. It is used in the field of bioconjugation and can be used to attach other molecules to the PEG backbone.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
