| Common Name | 4-Hydroxyifosfamide |
|---|
| Description | 4-Hydroxyifosfamide is the active metabolite of the bifunctional alkylating cytostatic drug known as ifosfamide. 4-Hydroxyifosfamide is a member of the compound class known as oxazaphosphorines. Oxazaphosphorines are any saturated six-membered heterocycle containing three carbon atoms and one each of oxygen, nitrogen and phosphorus, especially one in which the phosphorus atom is linked to both the nitrogen and oxygen atoms. 4-Hydroxyifosfamide is very unstable in plasma and a stabilization procedure by adding citric acid has been developed (PMID: 9172103 ). 4-Hydroxyifosfamide is known to pass through the blood-brain barrier, and can reach cerebrospinal fluid concentrations that are almost as high as plasma concentrations (PMID: 9677448 ). 4-Hydroxyifosfamide is only found in individuals who have consumed or received the drug Ifosfamide. |
