Dihydropyridines 120-136 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 16-32 2131820-7 1990 These results are interpreted in terms of an electron/proton/electron transfer mechanism previously postulated for the oxidation of other dihydropyridines by cytochrome P-450 enzymes and model one-electron acceptors and argue against a mechanism involving hydrogen atom abstraction from nifedipine. Dihydropyridines 138-154 cytochrome P450 family 4 subfamily F member 3 Homo sapiens 158-174
