Ifosfamide mechanism

Ifosfamide (eye fos' fa mide) is an analogue of cyclophosphamide and thus a nitrogen mustard-like alkylating agent that is used in the therapy of several forms of leukemia, lymphoma and solid organ cancer. Like cyclophosphamide, ifosfamide requires activation in the liver to form its active intermediaries which act by modifying and cross linking purine bases in DNA, thus inhibiting DNA, RNA and protein synthesis and leading to programmed cell death (apoptosis) in rapidly dividing cells.
