Hydroxylation and N-dechloroethylation of Ifosfamide and deuterated Ifosfamide by the human cytochrome p450s and their commonly occurring polymorphisms.
The hydroxylation and N-dechloroethylation of deuterated ifosfamide (d4IFO) and ifosfamide (IFO) by several human P450s have been determined and compared. d4IFO was synthesized with deuterium at the alpha and alpha' carbons to decrease the rate of N-dechloroethylation and thereby enhance hydroxylation of the drug at the 4' position. The purpose was to decrease the toxic and increase the efficac...
متن کاملContribution of CYP3A5 to hepatic and renal ifosfamide N-dechloroethylation.
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. W...

The hydroxylation and N-dechloroethylation of deuterated ifosfamide (d4IFO) and ifosfamide (IFO) by several human P450s have been determined and compared. d4IFO was synthesized with deuterium at the alpha and alpha9 carbons to decrease the rate of N-dechloroethylation and thereby enhance hydroxylation of the drug at the 49 position. The purpose was to decrease the toxic and increase the efficac...
متن کاملRole of human liver microsomal CYP3A4 and CYP2B6 in catalyzing N-dechloroethylation of cyclophosphamide and ifosfamide.
The anticancer alkylating agents cyclophosphamide (CPA) and ifosfamide (IFA) are prodrugs that undergo extensive P450-catalyzed metabolism to yield both active (4-hydroxylated) and therapeutically inactive but neurotoxic (N-dechloroethylated) metabolites. Whereas the human liver microsomal P450 catalysts of CPA and IFA 4-hydroxylation are well characterized, the P450 enzyme catalysts of the alt...
متن کاملthe relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
