Compared with human hepatocytes, expression of P450 in HepaRG cells was in general lower with the exception for a considerably higher expression of CYP3A4 and CYP7A1.

Drug Metab Dispos. 2007 Jun;35(6):875-83. Epub 2007 Mar 7.

In addition, pharmacokinetics of ML3403 were evaluated in male and female Wistar rats after oral gavage, showing a fast and high conversion to its active sulfoxide metabolite ML3603.
Incubations were carried out with hepatic microsomes from various species and with recombinant human cytochrome P450 isoenzymes, showing that CYP1A2, CYP2C19, CYP2D6, and CYP3A4 are the prominent enzymes in the metabolism of ML3403.

Thus, CYP1A2, CYP2B6, and CYP3A4 were found to accurately respond to their respective prototypical inducers, i.e., omeprazole, phenobarbital, and rifampicin.

This was achieved by comparing basal and inducible or metabolic activities of isoforms CYP1A1, CYP1A2, CYP2C6, CYP2D2, and CYP3A in rat hepatocytes that were cryopreserved with WPE, relative to fresh cells and those cryopreserved with DMSO.

The aim of the present study was to investigate potential drug interactions between the benzimidazoles albendazole and mebendazole and the potent CYP3A4 inhibitor ritonavir.
AUC, C (max), and t (1/2) of mebendazole, albendazole, and albendazole sulfoxide were studied in absence and after short-term (2 doses) and long-term (8 days) treatment with ritonavir 200 mg bid.

Using a cytochrome P450 3A4 Vivid Blue assay (Invitrogen, Carlsbad), we investigated the rate, pattern, and quantity of evaporation over a 1-year time frame to identify best practices for long-term (i.e., 6 months or greater) storage of assay-ready compound plates.
