C5H12ClN2O2P (198.0325)

3-Dechloroethylifosfamide is an inactive metabolite of the antitumour, alkylating drug Ifosfamide. It is a member of the compound class called 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. It is formed from its side-chain oxidation leading to the liberation of chloroacetaldehyde (PMID: 9054957). 3-dechloroethylifosfamide can be biosynthesized from ifosfamide through the action of several CYP450 enzymes including CYP3A4, CYP3A5, and CYP2B6 (PMID: 15875221). The duration of ifosfamide infusion influences the amount of 3-dechloroethylifosfamide that is produced (PMID: 11408362). 3-dechloroethylifosfamide is only found in individuals who have consumed or received the drug Ifosfamide.

4-maleyl-acetoacetate is slightly soluble (in water) and a moderately acidic compound (based on its pKa). 4-maleyl-acetoacetate can be found in a number of food items such as grass pea, vanilla, burdock, and pomegranate, which makes 4-maleyl-acetoacetate a potential biomarker for the consumption of these food products.

A hydroxybenzoic acid that is isophthalic acid (benzene-1,3-dicarboxylic acid) in which the hydrogens at positions 4 and 5 have been replaced by hydroxy groups. An inhibitor of brain glutamate decarboxylase.
