Disclosed is a method of making conjugates of cell binding agents and small molecule drugs comprising reacting a cell binding agent with a bifunctional cross-linking moiety to thereby provide the cell binding agent with a reactive disulfide group and then reacting the modified cell binding agent with a small molecule drug comprising a free thiol group. Bifunctional cross-linking moieties are also disclosed.
Provided herein are novel maytansinoid compounds of general formula I. Also provided herein are conjugates comprising the compounds linked to a binding protein via a linker, and conjugating reagents comprising the compounds attached via a linker to at least one functional group capable of reacting with a binding protein. Also provided herein are pharmaceutical compositions comprising the compounds and conjugates, therapeutic methods and uses involving the compounds and conjugates, for example in cancer therapy, and novel synthetic processes.
