1 The present study identifies the specific human cytochrome P-450 (CYP) enzymes involved in hydroxylation leading to activation of the anticancer drug cyclophosphamide and its isomeric analogue, ifosphamide. Cyclophosphamide cytochrome P450 family 4 subfamily F member 3 Homo sapiens
2 The present study identifies the specific human cytochrome P-450 (CYP) enzymes involved in hydroxylation leading to activation of the anticancer drug cyclophosphamide and its isomeric analogue, ifosphamide. Cyclophosphamide cytochrome P450 family 4 subfamily F member 3 Homo sapiens
3 Furthermore, growth of cultured CYP2A6- and CYP2B6-expressing B-lymphoblastoid cells, but not of CYP-negative control cells, was inhibited by cyclophosphamide and ifosphamide as a consequence of prodrug activation to cytotoxic metabolites. Cyclophosphamide cytochrome P450 family 4 subfamily F member 3 Homo sapiens
