  • Cells were grown for 6-8 days in presence of increasing concentrations of (I) bendamustine. Relative toxicity of the drugs was determined by the WST-8 cell proliferation assay, Dashed lines with open circles or triangles indicate cell proliferation in absence of an anti-lymphoma drug. Other curves represent the cells grown in increasing concentrations (indicated by the associated number) of the tested drug. Maximal absorbance (highest number of viable cells) of cells grown without an anti-lymphoma agent in each experiment was set as 100%. Standard deviations were < 5% for all measurements.

  • Inhibition of DNA Synthesis by SGI-1776 (S) and Bendamustine (B) and Their Combination in JeKo-1 Cells. JeKo-1 Cells Were Treated With Dimethyl Sulfoxide (DMSO), 5 μM or 10 m M Bendamustine, 5 μM SGI-1776, or 5 μM or 10 m M Bendamustine Combined With 5 μM SGI-1776 for 24 Hours. Cells were Then Incubated With [Methyl-3H]-Thymidine at 0.8 m Ci/mL Concentration for 45 Minutes. Radioactive Incorporation Was Then Measured by Scintillation Count, and Values Were Recorded as Disintegration per Minute per Cell and Normalized to DMSO Controls. Experiments Were Performed in Triplicate and Presented as Mean ± Standard Error of the Mean.

Biological Activity

Description Bendamustine HCL is a DNA-damaging agent with IC50 of 50 μM in cell-free assay.
DNA synthesis [1]
(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. [1] 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. [2] 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. [3]

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).

  • Cell lines: SU-DHL-1 and SU-DHL-9 cells
  • Concentrations: 0-100 μM
  • Incubation Time: 72 hours
  • Method: SU-DHL-1 and SU-DHL-9 cells are preincubated for 30 minutes with either 6 mM methoxyamine or 50 μM O6-benzylguanine, inhibitors of Ape-1 base excision repair enzyme, or alkylguanyl transferase enzyme, respectively. The cells are then exposed to various concentrations of Bendamustine for 72 hours. Cytotoxicity is evaluated by the MTT viability assay and an IC50 is determined as the drug concentration that inhibited by 50% the viability value of the untreated control. Analyses are done.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
