Although the exact mechanism of action of bendamustine is unknown, this agent appears to alkylate and crosslink macromolecules, resulting in DNA, RNA and protein synthesis inhibition, and eventually the induction of apoptosis.
(Bendamustine, NCI Thesaurus)
The reactive parts of a macromolecule that directly participate in its specific combination with a drug.
(Drug Binding Site, NCI Thesaurus)
Bendamustine metabolites alkylate and crosslink macromolecules, resulting in DNA, RNA and protein synthesis inhibition, and, subsequently, apoptosis.
