Regulation of cytochrome P450 mRNA expression in primary porcine hepatocytes by selected secondary plant metabolites from chicory (Cichorium intybus L.) [PDF]
Chicory (Cichorium intybus) has been shown to induce enzymes of pharmacokinetic relevance (cytochrome P450; CYP). The aim of this study was to investigate the effects of selected secondary plant metabolites with a global extract of chicory root, on the ...

Breaking tolerance to the natural human liver autoantigen cytochrome P450 2D6 by virus infection [PDF]
Autoimmune liver diseases, such as autoimmune hepatitis (AIH) and primary biliary cirrhosis, often have severe consequences for the patient. Because of a lack of appropriate animal models, not much is known about their potential viral etiology. Infection

Lenacapavir initiation with concomitant primidone: A case report with therapeutic drug monitoring
Lenacapavir (LEN), a first‐in‐class capsid inhibitor, has unique pharmacokinetics that enable twice‐yearly dosing. LEN is not extensively metabolized, although it is a substrate of CYP3A4, which introduces drug–drug interactions concerns. As adoption and implementation of LEN for treatment and prevention increase, additional guidance on concomitant ...

Epidemiological studies have shown that head and neck cancer (HNC) is a complex multistage process that in part involves exposure to a combination of carcinogens and the capacity of certain drug-metabolising enzymes including cytochrome P450 (CYP) to ...

7-Ethynylcoumarins: Selective Inhibitors of Human Cytochrome P450s 1A1 and 1A2 [PDF]
To discover new selective mechanism-based P450 inhibitors, eight 7-ethynylcoumarin derivatives were prepared through a facile two-step synthetic route. Cytochrome P450 activity assays indicated that introduction of functional groups in the backbone of coumarin could enhance the inhibition activities toward P450s 1A1 and 1A2, providing good selectivity ...
