Pharmacological regulation of the activity of cytochrome P450 3A4 AND P450 2C9 isoenzymes by vitamins and natural compounds

Регуляторные исследования и экспертиза лекарственных средств, 2018
The influence of vitamins with antioxidant properties (vitamins A, E, C), B vitamins (B1, B2, B6) and vitamin-like substances (coenzyme Q10, taurine and L-carnitine) on the enzymes of the first phase of xenobiotic metabolism - cytochromes P450 3A4 and ...

Quantitative prediction of intravenous drug interactions caused by cytochromes P450 inhibitors and inducers

British Journal of Clinical Pharmacology, EarlyView.
Background Aims Pharmacokinetic interaction studies typically focus on oral administration, but intravenous (IV) administration bypasses intestinal degradation and hepatic first‐pass metabolism, leading to distinct drug–drug interaction (DDI) magnitude. This study aimed to develop a predictive model for DDIs involving IV‐administered drugs.

Proteogenomic characterization of cholangiocarcinoma

Hepatology, EarlyView., 2022
Proteogenomic characterization of cholangiocarcinoma with therapeutic strategies Abstract Background and Aims Cholangiocarcinoma (CCA) is a highly heterogeneous cancer with limited understanding and few effective therapeutic approaches. We aimed at providing a proteogenomic CCA characterization to inform biological processes and treatment ...

Contraindicated drug–drug interactions and associated adverse drug reactions in an observational cohort study of 4543 paediatric hospitalized patients

British Journal of Clinical Pharmacology, EarlyView.
Abstract Background and Purpose Drug–drug interactions (DDIs) are associated with an increased risk of adverse drug reactions (ADRs). Hospitalized children are particularly vulnerable to DDIs and ADRs due to polypharmacy, frequent use of unlicensed or off‐label medications, and dosing regimens often extrapolated from adult data.

Combinatorial targeting of G‐protein‐coupled bile acid receptor 1 and cysteinyl leukotriene receptor 1 reveals a mechanistic role for bile acids and leukotrienes in drug‐induced liver injury

Hepatology, EarlyView., 2022
CHIN117 is a dual cysteinyl leukotriene receptor 1 (CYSLTR1) antagonist and G‐protein‐coupled bile acid receptor 1 (GPBAR1) agonist. In the liver, GPBAR1 and CYSLTR1 are coexpressed by liver sinusoidal endothelial cells (LSECs), HSCs, circulating monocytes/macrophages, and liver resident macrophages (Kupffer cells).

HLA genotype testing for carbamazepine, oxcarbazepine and eslicarbazepine: A guideline developed by the UK Centre of Excellence in Regulatory Science and Innovation in Pharmacogenomics (CERSI‐PGx)

British Journal of Clinical Pharmacology, EarlyView.
Carbamazepine is licensed in the United Kingdom for the treatment of epilepsy, bipolar disorder and trigeminal neuralgia. The related compounds oxcarbazepine and eslicarbazepine are licensed for the treatment of epilepsy. These drugs can cause immune‐mediated hypersensitivity reactions, which typically affect the skin, and can be of variable severity ...

Physiologically‐based pharmacokinetic modelling of uridine 5′‐diphosphoglucorosultransferase (UGT) substrate drugs in pregnant women

British Journal of Clinical Pharmacology, EarlyView.
Aims While pregnancy‐related changes in phase I enzyme activity are well‐documented, less is known about the impact on phase II enzymes. This study aimed to test the hypothesis that changes in the pharmacokinetics (PK) of uridine 5′‐diphosphoglucuronosyltransferase (UGT) substrates during pregnancy result from altered enzyme expression or activity ...

Endogenous melatonin partial metabolic clearance as a potential endogenous marker of CYP1A2 activity

British Journal of Clinical Pharmacology, EarlyView.
Aims Cytochrome P450 1A2 (CYP1A2) exhibits substantial interindividual variability, necessitating appropriate phenotyping strategies for personalized pharmacotherapy. This study evaluated endogenous melatonin partial metabolic clearance (CLm(MEL)), calculated from urinary 6‐hydroxymelatonin (6‐O‐MEL) excretion and plasma melatonin (MEL) exposure, as a ...

Hole migration in cytochrome P450

QRB Discovery
The cytochrome P450 enzymes catalyze the hydroxylation of organic substrates by dioxygen. The high-potential reactive intermediate in cytochrome P450 catalysis, compound I (CI), has the capacity to deliver oxidizing equivalents (holes) to the side chains
