1 Induction of hepatic CYP1A2 by the oral administration of caffeine to rats: lack of association with the Ah locus. Caffeine cytochrome P450, family 1, subfamily a, polypeptide 2 Rattus norvegicus
2 Immunoblot analysis revealed that caffeine gave rise to a dose-dependent increase in the hepatic CYP1A2, and at the highest dose only, CYP2B apoprotein levels. Caffeine cytochrome P450, family 1, subfamily a, polypeptide 2 Rattus norvegicus
3 Molecular modelling revealed that the caffeine molecule could orientate itself within the putative CYP1A2 active site so as to facilitate demethylation of the N-1, N-3 and N-7 positions. Caffeine cytochrome P450, family 1, subfamily a, polypeptide 2 Rattus norvegicus
4 In conclusion caffeine, being essentially planar, is an inducer of CYP1A2 in rat liver. Caffeine cytochrome P450, family 1, subfamily a, polypeptide 2 Rattus norvegicus
