Disclosed are methods, compositions and uses of conjugates of prodrug forms of 2- pyrrolinodoxorubicin (P2PDox) with antibodies or antigen-binding fragments thereof (ADCs), with targetable construct peptides or with other targeting molecules that are capable of delivering the P2PDox to a targeted cell, tissue or pathogen. Once delivered to the target cell, the ADC or peptide conjugate is internalized, a highly toxic 2-pyrrolinodoxorubicin (2- PDox) is released intracellularly. The P2PDox-peptide or ADC conjugates are of use to treat a wide variety of diseases, such as cancer, autoimmune disease or infectious disease. |
