Mal-amido-(CH2COOH)2, compound 7a, is a maleimidoetl-containing intermediate for drophilic ADC linker[1].
Mal-amido-(CH2COOH)2 is a intermediate for linker. Bivalent doxorubicin (DOX)-dipeptides (16a-c) are finally prepared and conjugated to the monoclonal antibody BR96. The dipeptides are cleaved by lysosomal proteases following internalization of the resulting immunoconjugates[1].
