ABSTRACT:
The present invention relates to antitumor compounds of the formula I: ##STR1## wherein M is selected from the group consisting of an hydrogen atom, a peptide residue, and a protein residue linked to the carbon atom via the amino residue of .epsilon.-lysine present therein which can be an antibody used to target the anti-tumor agent to the malignant cells, and R can be an antitumor agent such as daunorubicin, doxorubicin, or an epirublicin derivative.
