摘要: The present invention relates to a conjugate of a cytotoxic drug/molecule to a cell-binding molecule with a bis-linker (a dual-linker) containing a 2,3-diaminosuccinyl group. It also relates to preparation of the conjugate of a cytotoxic drug/molecule to a cell-binding molecule with the bis-linker, particularly when the drug having functional groups of amino, hydroxyl, diamino, amino-hydroxyl, dihydroxyl, carboxyl, hydrazine, aldehyde and thiol for conjugation with the bis-linker in a specific manner, as well as the therapeutic use of the conjugates.

摘要: A conjugation of a cytotoxic drug to a cell-binding molecule with a bis-linker (dual-linker) as shown in Formula (I). Bis-linkage methods of making a conjugate of a cytotoxic drug/molecule to a cell-binding agent in a specific manner are also described, as well as application of the conjugates for the treatment of a cancer, or an autoimmune disease, or an infectious disease. wherein “” is an optional bond; X, Y, Z1, and Z2 are a functional group; m1 and n are a integer; L1 and L2 are a linker.
