Association between low body weight and cytochrome P‐450 enzyme activity in patients with anorexia nervosa [PDF]

open access: yesPharmacology Research & Perspectives, 2020
Very little is known to which extent severe underweight could affect cytochrome P‐450 (CYP) enzyme activity. In this study, 24 patients with anorexia nervosa at two occasions ingested single oral doses of five test drugs known to be metabolized by CYP1A2,

A Modeling Investigation of the CYP1A Drug Interactions of Riluzole [PDF]

open access: yesClinical and Translational Science
Cytochrome‐P‐450 (CYP)1A2 has been considered the major enzyme metabolizing riluzole since its approval. However, the inhibitor that was used in the original experiments, α‐naphthoflavone, is also a potent inhibitor of CYP1A1.

Pharmacokinetics of Caffeine: A Systematic Analysis of Reported Data for Application in Metabolic Phenotyping and Liver Function Testing

open access: yesFrontiers in Pharmacology, 2022
Caffeine is by far the most ubiquitous psychostimulant worldwide found in tea, coffee, cocoa, energy drinks, and many other beverages and food. Caffeine is almost exclusively metabolized in the liver by the cytochrome P-450 enzyme system to the main ...

Inhibition of baicalin on metabolism of phenacetin, a probe of CYP1A2, in human liver microsomes and in rats.

open access: yesPLoS ONE, 2014
Baicalin has been used as mainly bioactive constituent of about 100 kinds of traditional Chinese medicines in Chinese pharmacopoeia. The effect of baicalin on cytochrome P450 should be paid more attention because baicalin was used widely. The aim of this

Inhibitory Effect of Antituberculosis Drugs on Human Cytochrome P450-Mediated Activities

open access: yesJournal of Pharmacological Sciences, 2004
The potential for drug-drug interactions mediated by the inhibition of cytochrome P-450 (CYP) were concerned during antituberculosis therapy. However, the information regarding human CYP inhibition by antituberculosis drugs is limited to isoniazid.

Metabolism of six CYP probe substrates in fetal hepatocytes

open access: yesADMET and DMPK, 2016
Cytochrome P-450 (CYP) are the most common drug metabolizing enzymes and are abundantly expressed in liver apart from kidney, lungs, intestine, brain etc. Their expression levels change with physiological conditions and disease states.

Interaction Between CYP1A2-Related Caffeine Metabolism and Vitamin B12/Folate Status in Patients with Metabolic Syndrome: A Novel Biomarker Axis

open access: yesMetabolites
Background/Objectives: The prevalence of metabolic syndrome (MetS) is steadily increasing worldwide, driven by complex genetic, nutritional, and environmental factors. Caffeine metabolism, primarily mediated by CYP1A2 (though other enzymes such as CYP1A1
