, (2021/05/14)
PROBLEM TO BE SOLVED: To provide: a method for producing a connected body; a method for using the connected body in the production of a uniform conjugate; and a method for applying the conjugate in the treatment of cancer, infectious diseases, and autoimmune diseases. SOLUTION: A novel connected body is provided that includes a 2,3-di-substituted succinic acid group or a 2-mono-substituted or 2,3-di-substituted fumaric acid or maleic acid (trans (E)- or cis (Z)-butenedioic acid) group for conjugating 2 or more compounds/cytotoxic agents per connected body with a cell-binding molecule by specifically bridge-linking to a pair of thiol on the cell-binding molecule. The connected body is exemplified by the following general formula. SELECTED DRAWING: None COPYRIGHT: (C)2021,JPOandINPIT

What provided is the conjugation of cytotoxic to a cell-binding molecule with a bis-linker(dual-linker) as shown in Formula (I). It provides bis-linkage methods of making a conjugate of a cytotoxic drug molecule to a cell-binding agent in a specific manner. It also relates to application of the conjugates for the treatment of a cancer, or an autoimmune disease, or an infectious disease.

Synthetic analogues of the natural occurring dolastatin 10 are of great interest in cancer due to their potent in vitro activity and their uses as payloads in antibody drug conjugates (ADCs). Modification of the dolastatin 10 core scaffold has mainly focused on modifications of the P1, N-terminus, and P5, C-terminus, with minimal attention to the P2 subunit. In this paper we discuss the introduction of heteroatoms to the P2 side chain, which results in potent activity in vitro. The most active compounds contained azides in the P2 unit and required a phenylalanine-derived P5 subunit.
