1 Different modes of inhibition of mouse Cyp2a5 and rat CYP2A3 by the food-derived 8-methoxypsoralen. Methoxsalen cytochrome P450, family 2, subfamily a, polypeptide 3 Rattus norvegicus
2 There is no published data on the inhibition of CYP2A3 by 8-MOP. Methoxsalen cytochrome P450, family 2, subfamily a, polypeptide 3 Rattus norvegicus
3 By contrast, 8-MOP was able to inhibit CYP2A3-mediated coumarin 7-hydroxylase only in a non-competitive way (K(iu)=0.22 microM). Methoxsalen cytochrome P450, family 2, subfamily a, polypeptide 3 Rattus norvegicus
4 By contrast, 8-MOP was able to inhibit CYP2A3-mediated coumarin 7-hydroxylase only in a non-competitive way (K(iu)=0.22 microM). Methoxsalen cytochrome P450, family 2, subfamily a, polypeptide 3 Rattus norvegicus
5 In conclusion, we showed that 8-MOP inhibits Cyp2a5 and CYP2A3 through different mechanisms. Methoxsalen cytochrome P450, family 2, subfamily a, polypeptide 3 Rattus norvegicus
