PEG

Mal-PEG3-NHS ester, a noncleavable ADC linker, possesses a Maleimide group. It serves as a crucial component in the synthesis of antibody-drug conjugates[1].

Mal-PEG6-NHS ester is a noncleavable ADC linker comprising a Maleimide functional group, a 6-unit Polyethylene Glycol (PEG) spacer, and an N-Hydroxysuccinimide (NHS) ester moiety.

Mal-PEG6-PFP ester is a PEG-based linker for PROTACs that joins two essential ligands, facilitating selective protein degradation by leveraging the ubiquitin-proteasome system within cells.

Methyltetrazine-PEG5-NHS ester is a PROTAC linker belonging to the group of PEGs and is used for the synthesis of PROTAC molecules.

N-(Amino-PEG5)-N-bis(PEG4-acid) is a PEG-based PROTAC linker used for synthesizing PROTACs, consisting of an amino group and two terminal carboxylic acids[1].

The PEG-based PROTAC linker, N-(Azido-PEG2)-N-Boc-PEG3-NHS ester, is suitable for the synthesis of PROTACs[1].

Boc-C1-PEG3-C4-OH is an Alkyl/ether-based PROTAC linker used in the synthesis of PROTACs, characterized by their structure of two distinct ligands tethered by a linker, with one ligand binding to an E3 ubiquitin ligase and the other to the target protein, facilitating targeted protein degradation through the ubiquitin-proteasome system [1].

Boc-PEG4-C2-NHS ester is a PEG-based linker for PROTACs that joins two essential ligands to form PROTAC molecules, enabling selective protein degradation via the ubiquitin-proteasome system within cells.

Pomalidomide-PEG1-C2-N3, a conjugate of an E3 ligase ligand-linker, incorporates the cereblon ligand based on Pomalidomide and a 1-unit PEG linker, commonly used in PROTAC technology. This compound enables the design of the selective CDK6 PROTAC degrader CP-10, which effectively induces CDK6 degradation with a DC50 value of 2.1 nM[1].
