Mechanism of Action
1. In the liver, biotransformation of the drug takes place by the mixed-function oxidases.
2. Metabolites so formed are the active forms of the drug.
3. Metabolites binds with the nucleic acids along with other essential cell component.
4. In the DNA strand, alkylation takes place on the N-7 position of the guanine
5. This results in the formation of cross linkages between the DNA strands results in the death of cell. 
Structural Activity Relationship
- Replacement of the sulfur atom by nitrogen will lower the toxicity.
- 2-chloroethyl group is essential for the activity as the aziridine cation is formed by this only. Aziridine cation will attach with the alkylates of the DNA later.
- Binding with the amino group will increase the oral route availability o the drug
- The introduction of the substituted phenyl group will also increases the oral route availability of the drug.
- Aromatic ring introduction will increase the stability of the drug.
- Aromatic ring will further increase the distribution of the drug throughout the body.
- Benzimidazol ring can provide the local and faster action of the drug.
- Benzimidazol will further decrease the half life of compound. 
Methods of Synthesis
i. N-(2 –chloroethyl)-3-hydroxypropylamine hydrochloride is treated with POCl3.
ii. The product so formed is reacted with 2-chloroethlamine hydrochloride to give ifosfamide.
iii. The whole reaction takes place in the presence of triethylamine.
