DBCO-PEG4-Val-Cit-PAB-MMAE

DBCO-PEG4-Val-Cit-PAB-MMAE

DBCO-PEG4-Val-Cit-PAB-MMAE is an ADC linker featuring a DBCO group, a hydrophilic PEG spacer, a Val-Cit dipeptide, a PAB motif, and an MMAE warhead. The DBCO group is a click chemistry handle which readily reacts with azide groups on a target molecule to form stable triazole linkages, while the Val-Cit dipeptide is a protease-cleavable motif which releases the MMAE warhead into cells via an elimination mechanism within the PAB structure.
