Description
MC-Val-Cit-PAB-OH is a cleavable peptide linker. The Val-Cit was designed to be cleaved specifically by Cathepsin B. MC group is reactive with thiol moiety
Uses
N-[6-(2,5-Dihydro-2,5-dioxo-1H-pyrrol-1-yl)-1-oxohexyl]-L-valyl-N5-(aminocarbonyl)-N-[4-(hydroxymethyl)phenyl]-L-ornithinamide is used as a reagent to prepare antibody-drug conjugates, which are compounds that selectively deliver cytotoxic drugs to a tumour-associated antigen.
Application
MC-Val-Cit-PAB is a peptide linker that can be used to prepare antibody-drug conjugates (ADCs) for cancer therapy research. For example, CBP-1018, a dual-ligand PDC, is conjugated to MMAE via a cleavable linker (MC-Val-Cit-PABC) that can be cleaved by proteinase B
[1].
MC-Val-Cit-PAB can also be used to prepare cetuximab-vc-DOX-NPs conjugates, which have good tumor targeting ability and low systemic toxicity, and are a promising drug delivery targeting system
[2].
