4-Hydroxycyclophosphamide
4-Hydroxycyclophosphamide is a primary activation metabolite of cyclophosphamide and of mafosfamide (an experimental drug) after they partially metabolized by cytochrome P450 (PMID: 12021633). Cyclophosphamide is a chemotherapeutic used to suppress the immune system and to treat several cancers including lymphoma, multiple myeloma, leukemia, ovarian cancer, breast cancer and small cell lung cancer. After cyclphosphamide is converted to 4-hydroxycyclophosphamide it is then partially tautomerized into aldophosphamide, which easily enters live cells whereupon it is partially detoxified into inactive carboxycyclophosphamide by the enzyme ALDH. 4-Hydroxycyclophosphamide is also an intermediate metabolite in the formation of phosphoramide mustard, the active metabolite, and acrolein, the metabolite responsible for much of the toxicity associated with cyclophosphamides (PMID: 7059981). 4-Hydroxycyclophosphamide is not cytotoxic at physiologic pH, readily diffuses into cells and spontaneously decomposes into the active phosphoramide mustard. In human liver microsomes, 4-Hydroxycyclophosphamide formation correlates with known phenotypic markers of CYP2B6 activity, specifically formation of (S)-2-ethyl-1,5-dimethyl-3,3-diphenyl pyrrolidine and hydroxybupropion. In addition, it is reported that the CYP2B6 genotype is not consistently related to 4-Hydroxycyclophosphamide formation in vitro or in vivo (PMID: 21976622). 4-Hydroxycyclophosphamide is only found in individuals who have consumed the drug cyclophosphamide.

4-Hydroxyifosfamide
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.

Aldophosphamide
Detoxification of cyclophosphamide is effected, in part, by hepatic class 1 aldehyde dehydrogenase (ALDH-1)-catalyzed oxidation of aldophosphamide, a pivotal aldehyde intermediate, to the nontoxic metabolite, carboxyphosphamide. Detoxification of aldophosphamide may also be effected by enzymes, viz. Thus, NAD-linked oxidation and NADPH-linked reduction of aldophosphamide catalyzed by relevant erythrocyte enzymes were quantified. (PMID: 9394035) Class 1 aldehyde dehydrogenases (ALDH-1) function as drug resistance gene products by catalyzing the irreversible conversion of aldophosphamide, an active metabolite of cyclophosphamide, to an inert compound.

Arctic acid B
Arctic acid b, also known as arctate b, is a member of the class of compounds known as bi- and oligothiophenes. Bi- and oligothiophenes are organic compounds containing two or more linked thiophene rings. Thiophene is a five-member aromatic ring with one sulfur and four carbon atoms. Arctic acid b is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Arctic acid b can be found in burdock, which makes arctic acid b a potential biomarker for the consumption of this food product.
2-C-methyl-D-erythritol-2,4-cyclodiphosphate
2-c-methyl-d-erythritol-2,4-cyclodiphosphate is soluble (in water) and a moderately acidic compound (based on its pKa). 2-c-methyl-d-erythritol-2,4-cyclodiphosphate can be found in a number of food items such as papaya, yautia, italian oregano, and daikon radish, which makes 2-c-methyl-d-erythritol-2,4-cyclodiphosphate a potential biomarker for the consumption of these food products.
