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： Hydrophilic linkers are useful for linking drugs to cell-binding ligands in ligand-drug conjugates, such as antibody-drug conjugates. The ligand-drug conjugate includes a cell-binding ligand capable of binding to a particular cell population, and a drug connected to the ligand by a hydrophilic linker. The hydrophilic linker includes one or more hydrophilic groups that render the linker hydrophilic. The hydrophilic linker may also include functional groups at the two termini for coupling to the drug and the cell-binding ligand respectively.
