摘要: The present invention relates to the conjugates of Tubulysin derivatives (anologs) and cell-binding molecules using branched (side-chain) linkers, and the resulting conjugates have better pharmacokinetic properties, and thus can more accurately target and kill abnormal cells. The invention also relates to the conjugation methods of the Tubulysin derivatives (anologs) to cell-binding molecules, and methods for synthesizing the small molecules, and methods of using the conjugates for targeted therapy for cancers, infections and autoimmune diseases. The conjugates of Tubulysin derivatives with long branched linkers demonstrated increased half-life, minimal exposure to non-targeted cells, tissues or organs in system circulation, leading to reduced off-target toxicity.

摘要: The present invention relates to novel linkers containing a 2,3-disubstituted succinic group, or 2-monosubstituted, or 2,3-disubstituted fumaric or maleic (trans (E)-or cis (Z)-butenedioic), or acetylenedicarboxyl group for conjugation of a cytotoxic agent, and/or one or more different functional molecules per linker to a cell-binding molecule, through bridge linking pairs of thiols on the cell-binding molecule specifically. The invention also relates to methods of making such linkers, and of using such linkers in making homogeneous conjugates, as well as of application of the conjugates in treatment of cancers, infections and autoimmune disorders.

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.
