Bendamustine is a novel alkylating agent with a benzimidazole ring giving it purine analogue-like properties. Like other alkylating agents, bendamustine is thought to act by modifying and cross linking purine bases in DNA, thus inhibiting DNA, RNA and protein synthesis and leading to cell death in rapidly dividing cells. Bendamustine appears to have a special activity against B cell leukemias and lymphomas. MW: 394.71. Purity ≥98%
