WebMar 2, 2024 · Ifosfamide belongs to the class of the oxazaphosphorine alkylating agents. It is an inactive compound in its parent form (prodrug). It is metabolized in the liver by CYP450 enzymes to active metabolites. These active metabolites (phosphoramide mustard derivatives and acrolein) bind to DNA and inhibit DNA synthesis. [13] WebThis metabolite is only formed in cells that have low levels of ALDH. Phosphoramide mustard forms DNA crosslinks both between and within DNA strands at guanine N-7 positions (known as interstrand and intrastrand crosslinkages, respectively). This is irreversible and leads to cell death.
