The proper mechanism of Ifosfamide has not been described but occur to be like other alkylating agents. Ifosfamide needed biotransformation in the Hepatic by mixed-function oxidases (cytochrome P450 system) before it becomes active. After metabolic activation, active metabolites of Ifosfamide alkylate or mix with many intracellular molecular structures, containing nucleic acids. The cytotoxic activities are mainly via the alkylation of DNA, done by affix the N-7 position of guanine to its reactive electrophilic groups. The inter and intra strand cross-links formation in the DNA causes in cell death.
