N-(m-PEG4)-N'-(4-Hydroxycyclohexyl-1-amido-PEG4)-Cy5 is a polyethylene glycol (PEG)-based linker compound primarily utilized in the synthesis of proteolysis-targeting chimeras (PROTACs)[1].
DBCO-(PEG)3-VC-PAB-MMAE is a chemical compound where monomethyl auristatin E (MMAE), a potent tubulin inhibitor acting as a toxin payload in antibody-drug conjugates, is conjugated to a DBCO-(PEG)3-vc-PAB linker.
N-Succinimidyl 3-(Bromoacetamido)propionate is a PEG-based PROTAC linker employed in the synthesis of PROTACs and antibody-drug conjugates (ADCs) [1, 2]. It acts as a cleavable ADC linker, facilitating the conjugation of drugs to antibodies for targeted delivery [2].
N-Boc-PEG-t-butyl ester 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.
