Cytochrome P-450 CYP1A2 (C0207509)

Definition (MSH) A cytochrome P-450 monooxygenase that can be induced by polycyclic aromatic xenobiotics in the liver of human and several animal species. This enzyme is of significant clinical interest due to the large number of drug interactions associated with its induction and its metabolism of THEOPHYLLINE. Caffeine is considered to be a model substrate for this enzyme. CYP1A2 activity can also be increased by environmental factors such as cigarette smoking, charbroiled meat, cruciferous vegetables, and a number of drugs including phenytoin, phenobarbital, and omeprazole.
Definition (NCI) A polycyclic aromatic hydrocarbon-inducible cytochrome which is of significant clinical interest due to the large number of drug interactions associated with induction and inhibition of theophylline. Caffeine is considered to be a model substrate for this enzyme. It also metabolizes theophylline and antipyrene. Environmental factors including cigarette smoking, charbroiled meat, cruciferous vegetables, and a number of drugs including phenytoin, phenobarbital, and omeprazole produce increases in CYP1A2 activity.
