Chemical compound

Mafosfamide (INN) is an oxazaphosphorine (cyclophosphamide-like) alkylating agent under investigation as a chemotherapeutic. It is metabolized by cytochrome P450 into 4-hydroxycyclophosphamide, which is then converted into aldophosphamide, which, in turn yields the cytotoxic metabolites phosphoramide mustard and acrolein.^[1]

Several Phase I trials have been completed.^[2]^[3]
