Fmoc-Val-Cit-PAB-PNP 是一种可降解 (cleavable) 的 ADC linker，可用于合成抗体偶联药物 (ADC)。 Fmoc-Val-Cit-PAB-PNP 的血浆稳定性优于不可降解连接剂。

Fmoc-Val-Cit-PAB-PNP is a cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs). Fmoc-Val-Cit-PAB-PNP has superior plasma stability comparable to that of non-cleavable linkers.

Fmoc-Val-Cit-PAB-PNP contains peptide sequence degradable by a lysosome enzyme.
Cathepsin B in the lysosome cleaves the peptide bond between Cit-PAB of dipeptide linkers containing Valine (Val)-citrulline (Cit) and p-aminobenzylalcohol (PAB). When PAB and a drug are binded covalently with carbamate bonds, the drug can be released by hydrolysis after cleavage of the peptide bond between Cit-PAB. Antibody-drug conjugates (ADCs) has been developed using this mechanism.

Fmoc-Val-Cit-PAB-PNP linker stabilization in the mouse is an essential prerequisite for designing successful efficacy and safety studies in rodents during preclinical stages of ADC programs.
Conjugation site plays an important role in determining VC-PABC linker stability in mouse plasma, and that the stability of the linker positively correlates with ADC cytotoxic potency both in vitro and in vivo.
