The present invention provides methods of preparing a cell-binding agent-cytotoxic agent conjugate comprising a cell-binding agent (CysCBA) having one or more unpaired cysteine residues covalently linked to a cytotoxic agent. Also provided are conjugates prepared by the methods described herein and pharmaceutical composition and methods of use thereof.
Ion-paired chiral ligands for asymmetric palladium catalysis
Conventional chiralligands rely on the use of a covalently constructed, single chiral molecule embedded with coordinative functional groups. Here, we report a new strategy for the design of a chiralligand for asymmetric transition-metal catalysis; our approach is based on the development of an achiral cationic ammonium–phosphine hybrid ligand paired with a chiral binaphtholate anion. This ion-paired
