Mafosfamide is a synthetic oxazaphosphorine derivative with antineoplastic properties. Mafosfamide alkylates DNA, forming DNA cross-links and inhibiting DNA synthesis. The effects of mafosfamide on various types of cancer cells were determined during preclinical investigations and clinical trials. Its development has been discontinued.
