Mechanism of Action

Targets/IC₅₀/Ki	DNA synthesis (Cell-free assay)
In vitro	DNA single- and double-strand breaks caused by Bendamustine are more extensive and significantly more durable than those caused by cyclophosphamide, cisplatinum, or carmustine. Bendamustine specifically regulates, transcriptionally and posttranslationally, genes involved in apoptosis, DNA repair, and mitotic checkpoints. Bendamustine uniquely regulates DNA repair pathways in non–Hodgkin's lymphoma cells compared with other alkylators. Bendamustine inhibits mitotic checkpoints and induces mitotic catastrophe. Treatment with Bendamustine results in a 60% to 80% down-regulation of the mRNA expression of all three of these genes [polo-like kinase 1 (PLK-1), Aurora Kinase A, and cyclin B1] in SU-DHL-9 cells. Twenty-six percent of the Bendamustine-treated MCF-7/ADR cells showed micronucleation compared with only 6% in DMSO control cells. Using Bendamustine alone in concentrations from 1 μg/mL to 50 μg/mL, a dose- and time-dependent manner of cytotoxicity from 30.4% to 94.8% after 48 hours could be observed. The LD50 for untreated and pretreated CLL cells is 7.3 or 4.4 μg /mL, respectively. Myeloid and breast carcinoma cell lines are resistant towards Bendamustine with the exception of HL-60 cells which exhibit an intermediate sensitivity. Bendamustine is found to have a very low clastogenic effect as compared with equimolar doses of lomustine.
In vivo	A single dose of Bendamustine at 25 mg/kg demonstrates significant activity in all three tumor lines (DoHH-2, Granta 519 and RAMOS). DoHH-2 is the most sensitive, with 30% ORR and a 69% inhibition in tumor growth. Growth of Granta 519 and RAMOS is also inhibited by Bendamustine (%TGI of 74% and 81%, respectively), and the effect is more durable in Granta 519 (%TGD of 124%) than for DoHH-2 or RAMOS (69% and 43%, respectively).
