Summary: | This invention relates to the field of immune therapy of cancer, more specifically to immunoconjugates of a cytotoxic moiety with a targeting moiety, more specifically to immunoconjugates of antibodies or fragments or functional derivatives of antibodies coupled to a cytotoxic substance such as drugs, toxins or radioisotopes. It especially relates to the release of substances bound to a targeting moiety through the use of acid-cleavable linker molecules derived from compounds of formula I. wherein: R1 = H, lower alkyl, -N-lower alkyl, -O-lower alkyl, -S-lower alkyl, -N-lower aralkyl, -O-lower aralkyl, -S-lower aralkyl, -N-lower alkylene, -O-lower alkylene, -S-lower alkylene, -N-lower aryl, -O-lower aryl, -S-lower aryl, R2 = H, lower alkyl, lower aralkyl, lower aryl R3 is or another chemical structure which is able to decolize the lone pair electrons of the Nitrogen and R4 is a pendant reactive group, capable of linking R3 to a carrier molecule, a proteinaceous substance, an antibody (fragment), a polymer or a nucleic acid. |
