To investigate the propensity of plumbagin to inhibit the three isoforms of human cytochrome P450 (CYP), i.e., CYP1A2, CYP2C19, and CYP3A4 using human liver microsomes in vitro. Inhibitory effects of plumbagin on the three human CYP isoforms were investigated using pooled
We describe a new molecular mechanism of cell death by excitotoxicity mediated through nuclear transcription factor kappa B (NF kappa B) in rat embryonic cultures of dopaminergic neurons. Treatment of mesencephalic cultures with alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) resulted in a number
CYP3As catalyze nifedipine oxidation in pig liver microsomes: Enzyme kinetics, inhibition and functional expression
Chemical research in toxicology, 2(1), 57-59 (1989-01-01)
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

Oral administration of nifedipine (20 and 30 mg tablets) to six volunteers was associated with a bioavailability of 0.43 and the presence of its nitropyridine analogue in the plasma. This metabolite was present in only trace amounts in samples taken
