MECHANISM OF ACTION
Bendamustine consist of bifunctional mechlorethamine derivative capable of forming electrophilic alkyl groups which covalently attach to other molecules. Due to this function as an alkylating agent, bendamustine occurs intra- and inter-strand crosslinks between DNA bases resulting in cell death. It is active against both active and quiescent cells, even though theproper mechanism of action is unknown
