Which of the following drugs also has alkylating properties and is used in oncology?

Ifosfamide is an alkylating agent used in oncology, which distinguishes it from the other drugs listed. Alkylating agents function by adding alkyl groups to DNA, leading to cross-linking and subsequent disruption of DNA replication and transcription. This mechanism is particularly effective in cancer treatment because it targets rapidly dividing cells, which are a hallmark of many types of tumors.

In contrast, the other drugs in the list work through different mechanisms. Cisplatin is a platinum-based compound that forms DNA cross-links but does so through a different process that does not involve alkylation specifically. Doxorubicin is an anthracycline antibiotic that primarily intercalates into DNA and inhibits topoisomerase II, disrupting DNA replication. Paclitaxel functions as a microtubule stabilizer, preventing normal mitotic spindle function during cell division.

Thus, the identification of Ifosfamide as possessing alkylating properties makes it the correct answer in this context.
