The primary deuterium isotope effect on Vm for the microsomal oxidation of the dihydropyridine calcium entry blocker nifedipine [4-(2-nitrophenyl)-2,6-dimethyl-3,5- bis(methoxycarbonyl)-1,4-dihydropyridine] has been measured. The magnitude of the kinetic isotope effect, 6.7, suggests that the rate-limiting step in the mechanism of

Humans are usually exposed to several pesticides simultaneously; consequently, combined actions between pesticides themselves or between pesticides and other chemicals need to be addressed in the risk assessment. Many pesticides are efficient activators of pregnane X receptor (PXR) and/or constitutive
