2. SN2 reactions to fight cancer Cyclophosphamide is a chemotherapy medication used to treat various types of cancers (i.e. lymphoma, leukemia, and breast cancer). It belongs to a group of cytotoxic alkylating agents known as Nitrogen mustards. The activity of these drugs is attributed to the chloroethylamine groups. CI R. 'N I R NH Cl + Cl R'-NH₂ Cyclophosphamide In this exercise, you will explore the mechanism responsible for the cytotoxic activity of Nitrogen mustards and how it is possible to tune their activity (therefore their toxicity) by modifying their chemical structure.
