Background:

Bendamustine HCl is an alkylating agent associated with DNA damage with IC50 of 50 μM [1].

It has been reported that bendamustine is activated under DNA damage stress and apoptosis. Bendamustine inhibits mitotic checkpoints and induces mitotic catastrophe by inhibiting several mitosis-related genes such as Polo-like kinase 1, Aurora kinase A, and Cyclin B1 [1]. In myeloma cell lines, bendamustine induced apoptosis by cleavage of caspase 3, and resulted in G2 cell cycle arrest [2]. In chronic lymphocytic and mantle cell lymphoma cell lines, bendamustine HCL has been shown to activate both the mitochondrial cell death pathway and caspase-dependent apoptosis. Some assays showed that bendamustine exhibited anti-proliferation effects on dexamethasone-sensitive (MM1.S) and -resistant (MM1.R) multiple myeloma cells in a dose-dependent manner, with IC50s of 119.8 μM (MM1.S) and 138 μM (MM1.R), respectively. The apoptosis by activation of caspase-3 and caspase-8 was induced in both MM1.S and MM1.R cell lines [4].
