Flunitrazepam 90-103 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 0-6 19005028-5 2009 By exposure to 100 microM flunitrazepam, nimetazepam, or nitrazepam, the cell viability in the presence of CYP3A4 decreased more than 25% compared with that of the control. Flunitrazepam 26-39 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 107-113 19005028-7 2009 These results suggested that nitrobenzodiazepines such as flunitrazepam, nimetazepam, and nitrazepam were metabolically activated by CYP3A4, which resulted in cytotoxicity. Flunitrazepam 58-71 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 133-139 11259331-1 2001 We have identified CYP2C19 and CYP3A4 as the principal cytochrome P450s involved in the metabolism of flunitrazepam to its major metabolites desmethylflunitrazepam and 3-hydroxyflunitrazepam. Flunitrazepam 102-115 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 31-37 11259331-8 2001 We estimate that the relative contributions of CYP2C19 and CYP3A4 to the formation of desmethylflunitrazepam in vivo are 63 and 37%, respectively, at therapeutic flunitrazepam concentrations (0.03 microM). Flunitrazepam 95-108 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 59-65 10873929-8 2000 Projected in vivo inhibition of CYP3A4-mediated metabolism of flunitrazepam by buprenorphine is 0. Flunitrazepam 62-75 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 32-38 10574680-0 1999 Flunitrazepam oxidative metabolism in human liver microsomes: involvement of CYP2C19 and CYP3A4. Flunitrazepam 0-13 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 89-95
