User: I have a question about the compound with SMILES O=[P@@]1(N(CCCl)CCCl)N[C@@H](SCCS(=O)(=O)O)CCO1.
Assistant: How can I help?
User: Please describe this drug.
Assistant: The answer is Mafosfamide is a synthetic oxazaphosphorine derivative with antineoplastic properties.  Mafosfamide alkylates DNA, forming DNA cross-links and inhibiting DNA synthesis.  Although closely related to cyclophosphamide, mafosfamide, unlike cyclophosphamide, does not require hepatic activation to generate its active metabolite 4-hydroxy-cyclophosphamide; accordingly, mafosfamide is potentially useful in the intrathecal treatment of neoplastic meningitis. (NCI04)
