Imidazopyridines as selective CYP3A4 inhibitors [PDF]

open access: yesBioorganic & Medicinal Chemistry Letters, 2012
Cytochrome P450s are the major family of enzymes responsible for the oxidative metabolism of pharmaceuticals and xenobiotics. CYP3A4 and CYP3A5 have been shown to have overlapping substrate and inhibitor profiles and their inhibition has been demonstrated to be involved in numerous pharmacokinetic drug-drug interactions. Here we report the first highly
