DBCO-Val-Cit-PABC-PNP
DBCO-Val-Cit-PABC-PNP (CAS 2994332-18-0) is a core cleavable linker for ADC (Antibody-Drug Conjugate) development, designed for precise targeted drug delivery. Mechanistically, the DBCO group enables efficient copper-free click conjugation with azide-containing biomolecules. After the ADC is internalized by tumor cells, cathepsin B in the lysosome specifically cleaves the Val-Cit dipeptide sequence. Subsequently, the PABC group undergoes self-immolative dissociation to release the drug payload. Main application scenarios include the construction of tumor-targeted ADCs, bioorthogonal labeling and in vivo imaging, and modification of nanodrug delivery systems. Additionally, the optimized C4 spacer arm enhances biocompatibility and plasma stability, providing a safe and efficient molecular tool for precision medicine.
