Biological Activity of Bendamustine Hydrochloride:
Bendamustine is a nitrogen mustard used in the treatment of chronic lymphocytic leukemias (CLL) and lymphomas. It is also being studied for the treatment of sarcoma. [1]
Betamustine acts as an alkylating agent causing intra-strand and inter-strand cross-links between DNA bases. Bendamustine may differ from other alkylators in that it may be more potent in activating p53-dependent stress pathways and inducing apoptosis; it may induce mitotic catastrophe; and it may activate a base excision DNA repair pathway rather than an alkyltransferase DNA repair mechanism. Accordingly, this agent may be more efficacious and less susceptible to drug resistance than other alkylators. [2]
This agent inhibited SU-DHL-1 cell proliferation with IC50 at 50 μm. [3]
