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.
本发明涉及2-吡咯烷基多柔比星(P2PDox)的前药形式与抗体或其抗原结合片段(ADC)、可靶向构建肽或其他靶向分子的结合物的共轭物的方法、组合物和用途,这些结合物能够将P2PDox递送到目标细胞、组织或病原体。一旦递送到目标细胞,ADC或肽共轭物被内吞,高毒性的2-吡咯烷基多柔比星(2-PDox)在细胞内释放。P2PDox-肽或ADC共轭物可用于治疗各种疾病,如癌症、自身免疫性疾病或传染病。
