Stereoselective metabolism of ifosfamide by human P-450s 3A4 and 2B6. Favorable metabolic properties of R-enantiomer.. P Roy; O Tretyakov; J Wright; D J Waxman (1999) Drug metabolism and disposition: the biological fate of chemicals display abstract
The anticancer prodrug ifosfamide (IFA) contains a chiral phosphorous atom and is administered clinically as a racemic mixture of R and S enantiomers. Animal model studies and clinical data indicate enantioselective differences in cytochrome P-450 (CYP) metabolism, pharmacokinetics, and therapeutic efficacy between the two enantiomers; however, the metabolism of individual IFA enantiomers has not been fully characterized. The role of CYP enzymes in the stereoselective metabolism of R-IFA and S-IFA was investigated by monitoring the formation of both 4-hydroxy (activated) and N-dechloroethyl (DCl) (inactive, neurotoxic) metabolites. In the 4-hydroxylation reaction, cDNA-expressed CYPs 3A4 and 3A5 preferentially metabolized R-IFA, whereas CYP2B6 was more active toward S-IFA. Enantioselective IFA 4-hydroxylation (R > S) was observed with six of eight human liver samples. In the N-dechloroethylation reaction, CYPs 3A4 and 2B6 both catalyzed a significantly higher intrinsic metabolic clearance (V(max)/K(m)) of S-IFA compared with R-IFA. Striking P-450 form specificity in the formation of individual DCl metabolites was evident. CYPs 3A4 and 3A5 preferentially produced (R)N2-DCl-IFA and (R)N3-DCl-IFA (derived from R-IFA and S-IFA, respectively), whereas CYP2B6 correspondingly formed (S)N3-DCl-IFA and (S)N2-DCl-IFA. In human liver microsomes, the CYP3A-specific inhibitor troleandomycin suppressed (R)N2- and (R)N3-DCl-IFA formation by >/=80%, whereas (S)N2- and (S)N3-DCl-IFA formation were selectively inhibited (>/=85%) by a CYP2B6-specific monoclonal antibody. The overall extent of IFA N-dechloroethylation varied with the CYP3A4 and CYP2B6 content of each liver, but was significantly lower for R-IFA (32 +/- 13%) than for S-IFA (62 +/- 17%, n = 8; p

Screening for inhibitory effects of antineoplastic agents on CYP3A4 in human liver microsomes.. M Baumhäkel; D Kasel; R A Rao-Schymanski; R Böcker; K T Beckurts; M Zaigler; D Barthold; U Fuhr (2001) International journal of clinical pharmacology and therapeutics display abstract
BACKGROUND: The human cytochrome P450 enzyme CYP3A4 is involved in the metabolism of many anticancer drugs. Since these drugs are usually administered in a polychemotherapy regimen, the objective of this study was to examine their inhibitory potency on CYP3A4 with regard to possible mutual drug interactions. METHOD: CYP3A4 activities in human liver microsomes from 2 donors were determined using the oxidation of the dihydropyridine denitronifedipine, a specific CYP3A4 substrate, at a concentration of 50 microM (= KM). Formation of the pyridine metabolite was measured using HPLC. Inhibitor concentrations used were 0.5, 5 and 50 microg/ml, except for cyclophosphamide and ifosfamide (0.5, 2.5 and 5 mg/ml) and for paclitaxel (0.05, 0.15, 0.5, 1.5 and 5 microg/ml). RESULTS: The following substances showed an inhibitory effect on CYP3A4 (IC50 values for the 2 microsome samples are parenthesized): cyclophosphamide (12.3/9.2 mmol/l), mafosfamide generated 4-OH-cyclophosphamide (152/163 [micromol/l), ifosfamide (3.6/2.5 mmol/l), vinblastine sulfate (20/44 micromol/l), vincristine sulfate (67/176 micromol/l), daunorubicin hydrochloride (206/200 micromol/l), doxorubicin hydrochloride (160/215 micromol/l), teniposide (64/84 micromol/l) and docetaxel (6.4/12.7 micromol/l). No inhibitory effect on CYP3A4 was observed with epirubicin, etoposide, paclitaxel, cytarabine, 5-FU, 6-mercaptopurine, methotrexate, cisplatin, carboplatin, bleomycin, busulfan, chlorambucil and mitomycin. CONCLUSION: Comparing IC50 values with plasma concentrations present during antineoplastic therapy, the agents cyclophosphamide, ifosfamide, vinblastine, teniposide and docetaxel could possibly cause clinical drug interactions by inhibition of CYP3A4. Some recently described clinical interactions with antineoplastic agents may be explained by these results.

Contribution of CYP3A5 to hepatic and renal ifosfamide N-dechloroethylation.. Jeannine S McCune; Linda J Risler; Brian R Phillips; Kenneth E Thummel; David Blough; Danny D Shen (2005) Drug metabolism and disposition: the biological fate of chemicals display abstract
Ifosfamide nephrotoxicity is attributed to the formation of a toxic metabolite, chloroacetaldehyde, via N-dechloroethylation, a reaction that is purportedly catalyzed by CYP3A and CYP2B6. Because allelic variants of CYP3A5 are associated with polymorphic expression of microsomal CYP3A5 in human liver and kidneys, we hypothesized that ifosfamide N-dechloroethylation depends on CYP3A5 genotype. We compared ifosfamide N-dechloroethylation activity in cDNA-expressed CYP3A4 and CYP3A5. Ifosfamide N-dechloroethylation was also assessed in liver (N = 20) and kidney (N = 21) microsomes from human donors with different CYP3A5 genotypes. Ifosfamide N-dechloroethylation was catalyzed by recombinant CYP3A5 at a rate comparable with recombinant CYP3A4. In human liver microsomes matched for CYP3A4 protein content, N-dechloroethylation was more than 2-fold higher in that from donors carrying CYP3A5*1 allele that express CYP3A5 relative to that from donors homozygous for the mutant CYP3A5*3. Correlation analysis revealed that ifosfamide N-dechloroethylation was significantly associated with CYP3A4 and CYP3A5 protein concentration but not with age, sex, or CYP2B6 protein concentration. In hepatic microsomes not expressing CYP3A5 protein, ifosfamide N-dechloroethylation was inhibited 53 to 61% and 0 to 3% by monoclonal antibodies specific for CYP3A4/5 or CYP2B6, respectively. Ifosfamide N-dechloroethylation was not detected in renal microsomes obtained from CYP3A5*3/*3 donors. In contrast, it was readily measurable in microsomes isolated from four kidneys of CYP3A5*1 carriers, which was almost completely inhibited by the CYP3A inhibitor ketoconazole. CYP2B6 protein could not be detected in this panel of human renal microsomes. In conclusion, CYP3A5*1 genotype is associated with higher rates of ifosfamide N-dechloroethylation in human liver and kidneys.

Identification of the major human hepatic cytochrome P450 involved in activation and N-dechloroethylation of ifosfamide.. D Walker; J P Flinois; S C Monkman; C Beloc; A V Boddy; S Cholerton; A K Daly; M J Lind; A D Pearson; P H Beaune (1994) Biochemical pharmacology display abstract
Two NADPH-dependent metabolic routes for the anticancer drug ifosfamide, 4-hydroxylation (activation) and N-dechloroethylation (a detoxication pathway), were studied in human liver microsomes to identify the cytochrome P450 enzymes involved. Naringenin, a grapefruit aglycone and an inhibitor of cytochrome P450 3A4 (CYP3A4)-catalysed reactions, was found to inhibit ifosfamide activation and N-dechloroethylation by human liver microsomes. IC50 for both reactions was of the order of 70 microM. The CYP3A4-specific inhibitor triacetyloleandomycin inhibited ifosfamide N-dechloroethylation by human liver microsomes with an IC50 of approximately 10 microM. Furthermore, anti-human CYP3A4 antiserum inhibited by about 80% N-dechloroethylation of ifosfamide by human liver microsomes. The relative levels of cytochromes P450 1A, 2C, 2E and 3A4 in 12 human livers were determined by western blotting analysis. A strong correlation (P < 0.001) was observed between CYP3A4 expression and both activation and N-dechloroethylation of ifosfamide. A role for human CYP3A4 in both pathways of ifosfamide metabolism was thus demonstrated. This was substantiated by the observation that the nifedipine oxidase activities of the 12 samples of human liver microsomes correlated with ifosfamide activation (P < 0.009) and N-dechloroethylation (P < 0.001). These findings have important clinical implications. The involvement of the same key cytochrome P450 enzyme in both reactions prohibits selective inhibition of the N-dechloroethylation pathway, as might be desirable to reduce toxic side effects. They also demonstrate the need to consider interaction with co-administered drugs that are CYP3A4 substrates.
