Description: MC-DM is a Maytansine derative and a DM1 molecule with an reactive linker MC. MC-DM1 is a useful precursor to make drug antibody congjuate (ADC) such as HER2-Targeting Affibody-DM1 Drug Conjugates. The resulting affibody drug conjugates were potent cytotoxic molecules for human cells over-expressing HER2, with sub-nanomolar IC50-values similar to trastuzumab emtansine, and did not affect cells with low HER2 expression. A biodistribution study of a radiolabeled version of (ZHER2:2891)2-ABD-MC-DM1, showed that it was taken up by the tumor. The major site of off-target uptake was the kidneys and to some extent the liver. (ZHER2:2891)2-ABD-MC-DM1 was found to have a half-life in circulation of 14 h. The compound was tolerated well by mice at 8.5 mg/kg and was shown to extend survival of mice bearing HER2 over-expressing tumors.
