Which alkylating agent is also known as Ifosfamide?

Ifosfamide is an alkylating agent that is primarily used in the treatment of various types of cancers, especially in solid tumors and lymphomas. It belongs to the class of nitrogen mustard compounds and is related to cyclophosphamide, another well-known alkylating agent.

The other options presented are distinct compounds without direct relation to Ifosfamide. Chlorambucil is a different nitrogen mustard used mainly for chronic lymphocytic leukemia and some lymphomas, while Bendamustine, a benzimidazole derivative, is used to treat non-Hodgkin lymphoma and chronic lymphocytic leukemia but operates via different mechanisms as an alkylating agent. Thiotepa, another alkylating agent, is utilized in the treatment of breast cancer and other solid tumors, but it does not share the same chemical structure or classification as Ifosfamide. Therefore, "None of the above" is accurate since none of the alternatives listed is another name for Ifosfamide.
