Cyclophosphamide and ifosfamide are two commonly used DNA-alkylating agents in cancer chemotherapy that undergo biotransformation to several toxic and non-toxic metabolites, including acrolein and chloroacetaldehyde (CAA). Acrolein and CAA toxicities occur by several different mechanisms, including ROS formation and protein
