Genetic predisposition to the metabolism of irinotecan (CPT-11). Role of uridine diphosphate glucuronosyltransferase isoform 1A1 in the glucuronidation of its active metabolite (SN-38) in human liver microsomes.

open access: yesJournal of Clinical Investigation, 1998
Irinotecan (CPT-11) is a promising antitumor agent, recently approved for use in patients with metastatic colorectal cancer. Its active metabolite, SN-38, is glucuronidated by hepatic uridine diphosphate glucuronosyltransferases (UGTs).

A Phenotyping Tool for Seven Cytochrome P450 Enzymes and Two Transporters: Application to Examine the Effects of Clopidogrel and Gemfibrozil

open access: yesClinical Pharmacology &Therapeutics, Volume 117, Issue 6, Page 1732-1742, June 2025.
Clinical cocktails for cytochrome P450 (CYP) phenotyping lack a marker for CYP2C8. We aimed to combine the CYP2C8 index drug repaglinide with the Geneva cocktail (caffeine/CYP1A2, bupropion/CYP2B6, flurbiprofen/CYP2C9, omeprazole/CYP2C19, dextromethorphan/CYP2D6, and midazolam/CYP3A4). We also included endogenous organic anion transporting polypeptide (

Identification of Genetic Variants Associated with Pravastatin and Pitavastatin Pharmacokinetics

open access: yesClinical Pharmacology &Therapeutics, Volume 117, Issue 6, Page 1763-1774, June 2025.
A clinical trial was carried out to investigate the pharmacogenetics of single‐dose pravastatin and pitavastatin pharmacokinetics in 173 and 164 healthy participants. Additionally, 96 participants were included from previous pharmacogenetic studies with pravastatin. In a genome‐wide meta‐analysis of pravastatin including all 269 participants, SLCO1B1 c.

Regulatory Effects of Betonica macrantha Extract, Known as Mountain Tea, on miRNA Expression and Its Pharmacokinetic Properties

open access: yesFood Science &Nutrition, Volume 13, Issue 6, June 2025.
Betonica macrantha methanol extract exhibited anticancer activity against MDA‐MB‐231 breast cancer cells (IC50: 0.8 mg/mL), upregulating miR‐19, miR‐20a, miR‐126, and miR‐200c. GC–MS and HPLC analyses identified key bioactive compounds, including α‐pinene, caryophyllene, and catechin, which showed favorable pharmacokinetics and target interactions ...
