use | 14-azide -3,6,9,12-tetraoxetanol is a polyethylene glycol (PEG) derivative used to prepare various targeted microenvironment sensors. |
biological activity | Azido-PEG5-alcohol is a non-cleavable ADC linker containing 5 unit PEG, which can be used to synthesize antibody-coupled drugs (ADC). Azido-PEG5-alcohol is also a PROTAC linker, belonging to the PEG class, which can be used to synthesize PROTAC molecules. |
target | PEGs Non-cleavable |
in vitro study | ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker. PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins. |
