Propofol 91-99 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 39-54 11298076-1 2001 AIMS: To determine the cytochrome P450 (CYP) isoforms involved in the oxidation of propofol by human liver microsomes. Propofol 83-91 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 23-38 11298076-1 2001 AIMS: To determine the cytochrome P450 (CYP) isoforms involved in the oxidation of propofol by human liver microsomes. Propofol 83-91 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 40-43 11298076-2 2001 METHODS: The rate constant calculated from the disappearance of propofol in an incubation mixture with human liver microsomes and recombinant human CYP isoforms was used as a measure of the rate of metabolism of propofol. Propofol 212-220 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 148-151 11298076-5 2001 The rate constants of propofol by microsomes were significantly correlated with S-mephenytoin N-demethylation, a marker of CYP2B6 (r = 0.93, P < 0.0001), but not with the metabolic activities of other CYP isoform-selective substrates. Propofol 22-30 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 123-126 11298076-6 2001 Of the chemical inhibitors of CYP isoforms tested, orphenadrine, a CYP2B6 inhibitor, reduced the rate constant of propofol by liver microsomes by 38% (P < 0.05), while other CYP isoform-selective inhibitors had no effects. Propofol 114-122 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 30-33 11298076-6 2001 Of the chemical inhibitors of CYP isoforms tested, orphenadrine, a CYP2B6 inhibitor, reduced the rate constant of propofol by liver microsomes by 38% (P < 0.05), while other CYP isoform-selective inhibitors had no effects. Propofol 114-122 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 67-70 11298076-7 2001 Of the recombinant CYP isoforms screened, CYP2B6 produced the highest rate constant for propofol metabolism (197 nmol min-1 nmol P450-1). Propofol 88-96 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 19-22 12067002-9 2002 RESULTS: Total recovery of propofol in the metabolites studied amounts to 38%, of which 62% was via the PG metabolite and 38% via cytochrome P-450. Propofol 27-35 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 130-146 9771309-2 1998 On the basis of potential influence of propofol on the metabolism of co-administered agents, many investigators have evaluated the effects of propofol on cytochrome P450 (CYP) activities. Propofol 142-150 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 154-169 9771309-2 1998 On the basis of potential influence of propofol on the metabolism of co-administered agents, many investigators have evaluated the effects of propofol on cytochrome P450 (CYP) activities. Propofol 142-150 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 171-174 9771309-3 1998 CYP isoforms involved in propofol metabolism are not defined. Propofol 25-33 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 0-3 9771309-4 1998 In this study, our objective was to elucidate further the CYP isoforms responsible for the hydroxylation of propofol. Propofol 108-116 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 58-61 9771309-10 1998 This low specificity among CYP isoforms may contribute to the low interindividual variability (two-fold) and may contribute to the low level of metabolic drug interactions observed with propofol. Propofol 186-194 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 27-30 15769884-1 2005 The polymorphic human cytochrome P450 (P450) 2B6 is primarily responsible for the metabolism of several clinically relevant drugs including bupropion, cyclophosphamide, propofol, and efavirenz. Propofol 169-177 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 22-48 7695156-9 1995 These results indicate that cytochrome P-450 metabolic pathways have an important role in propofol clearance and propofol anesthetic recovery in Greyhounds. Propofol 90-98 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 28-44 7695156-9 1995 These results indicate that cytochrome P-450 metabolic pathways have an important role in propofol clearance and propofol anesthetic recovery in Greyhounds.
