摘要 |
Chemotherapeutic conjugates of a peptide substrate to a phosphoramide chemotherapeutic agent in which a peptide substrate is covalently linked to the chemotherapeutic agent by a linker with an aminoarylmethyl or aminoheteroaryl moiety, wherein the linking of the peptide to the chemotherapeutic agent inhibits the cytotoxic activity of the chemotherapeutic agent, the peptide is a substrate for proteolytic cleavage by a tumor-specific enzyme; and the linker is capable of undergoing 1,6-elimination in vivo upon cleavage of the peptide substrate. Methods for synthesizing and methods of using the conjugates are also disclosed.
