m-PEG7-CH2CH2COOH is a non-cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs). m-PEG7-CH2CH2COOH is also a PEG-based PROTAC linker that can be used in the synthesis of PROTACs.
MAK683-CH2CH2COOH binds to EED (embryonic ectoderm development protein). MAK683-CH2CH2COOH and a VHL ligand for the E3 ubiquitin ligase have been used to design PROTAC EED degrader-1 (HY-130614) and PROTAC EED degrader-2 (HY-130615)[1].
