ACTIVE MOIETY
The IC50 of MKT-077 toward these tumor cell lines is more than 100 times lower than the IC50 against healthy cell lines. Because of these very favorable properties, MKT-077 has been evaluated as a cancer chemotherapeutic in a phase I trial. The trial was aborted because of the renal toxicity of MKT-077.
