1 CYP2A6 AND CYP2B6 are involved in nornicotine formation from nicotine in humans: interindividual differences in these contributions. Nicotine cytochrome P450 family 2 subfamily B member 6 Homo sapiens
2 The nicotine N-demethylase activity at 100 microM nicotine was significantly correlated with the CYP2B6 contents (r = 0.677, p < 0.05) and S-mephenytoin N-demethylase activities (r = 0.740, p < 0.005). Nicotine cytochrome P450 family 2 subfamily B member 6 Homo sapiens
3 These results as well as the inhibition analyses suggested that CYP2A6 and CYP2B6 would significantly contribute to the nicotine N-demethylation at low and high substrate concentrations, respectively. Nicotine cytochrome P450 family 2 subfamily B member 6 Homo sapiens
