propargyl-peg-2-acid

Propargyl-PEG2-acid is a non-cleavable 2-unit PEG ADC linker used in synthesizing antibody-drug conjugates (ADCs)[1].

N-(PEG2-C2-acid)-N-bis(PEG2-propargyl) is a polyethylene glycol (PEG)-based linker compound designed for the synthesis of PROTACs[1].

Propargyl-PEG4-acid is a PEG-based PROTAC linker can be used in the synthesis of BTK-IAP PROTACs Ibrutinib -based PROTAC 2 and an analogue PROTAC 3. PROTAC 3 causes BTK degradation with a DC50 of 200 nM in THP-1 cells[1].
