description
Linker for Antibody-Drug-Conjugation (ADC). In contrast to the hydroxybenzyl derivative ADC1350 the chloride is able to react with tertiary amines to form a linked quarternary amine. The Val-Ala will specifically be cleaved by Cathepsin B. As this enzyme is only present in the lysosome the ADC payload will be released only in the cell. The alkyne moiety allows versatile conjugation e.g. via Click Chemistry.
