lifosfamide

Palifosfamide (Isophosphamide mustard) lysine (ZIO-201) is a stable form of palifosfamide. Palifosfamide lysine has broad activity in sarcoma lines in vitro. The IC50 ranges from 2.25 to 6.75 μM for most cell lines except OS222 (IC50=31.5 μM).

Palifosfamide (tromethamine), a synthetically derived alkylating agent, exhibits potential antineoplastic properties. Acting as the stabilized active metabolite of ifosfamide, it irreversibly alkylates and crosslinks DNA at GC base pairs, inhibiting DNA replication and inducing cell death. Palifosfamide (tromethamine) boasts reduced toxicity in comparison to ifosfamide.

L-Ifosfamide is nitrogen mustard, a chemotherapeutic antineoplastic, and more precisely an alkylating agent structural analog of cyclophosphamide with respect to which presents some differences regard to the antitumor activity and spectrum.
