Physicochemical and biopharmaceutical characterization of new sulfonamide derivatives of gallic acid

open access: yesBritish Journal of Pharmacy, 2022
Gallic acid (GA) is known for its antioxidant activity which is restricted due to its low oral permeability. In this project the carboxylic group of (GA) was substituted with sulfonamide group and hydroxyl groups were methylated which resulted ...

Association of ABCB1, 5-HT3B receptor and CYP2D6 genetic polymorphisms with ondansetron and metoclopramide antiemetic response in Indonesian cancer patients treated with highly emetogenic chemotherapy. [PDF]

open access: yes, 2011
Our study shows that in Indonesian cancer patients treated with highly cytostatic emetogenic, carriership of the CTG haplotype of the ABCB1 gene is related to an increased risk of delayed chemotherapy-induced nausea and ...

Assessment of Activity Levels for CYP2D6*1, CYP2D6*2, and CYP2D6*41 Genes by Population Pharmacokinetics of Dextromethorphan [PDF]

open access: yesClinical Pharmacology & Therapeutics, 2010
The pharmacokinetics of dextromethorphan (DM) is markedly influenced by cytochrome P450 2D6 (CYP2D6) enzyme polymorphisms. The aim of this study was to quantify the effects of the CYP2D6*1, *2, and *41 variants on DM metabolism in vivo and to identify other sources of pharmacokinetic variability.

Dietary-Driven Gene Expansion. [PDF]

open access: yesClin Pharmacol Ther
Gene duplication has been shown to drive molecular evolution, with dietary pressures expanding detoxification genes across species. In humans, CYP2D6 gene duplications enhance alkaloid and drug metabolism, reflecting ancient dietary adaptations. Similarly, tobacco‐feeding aphids amplify CYP6CY3 for nicotine and insecticide resistance, and as recently ...

Physiology-based IVIVE predictions of tramadol from in vitro metabolism data [PDF]

open access: yes, 2014
To predict the tramadol in vivo pharmacokinetics in adults by using in vitro metabolism data and an in vitro-in vivo extrapolation (IVIVE)-linked physiologically-based pharmacokinetic (PBPK) modeling and simulation approach (SimcypA (R)).

A frequent CYP2D6 variant promotes skipping of exon 3 and reduces CYP2D6 protein expression in human liver samples

open access: yesFrontiers in Pharmacology, 2023
CYP2D6 is one of the most polymorphic drug-metabolizing enzymes in the liver. While genetic CYP2D6 variants serve as clinical biomarkers to predict CYP2D6 activity, large inter-person variability in CYP2D6 expression remains unaccounted for.

Pharmacogenetics of ophthalmic topical β-blockers [PDF]

open access: yes, 2008
Glaucoma is the second leading cause of blindness worldwide. The primary glaucoma risk factor is elevated intraocular pressure. Topical β-blockers are affordable and widely used to lower intraocular pressure.

The Effect of Polymorphisms in the CYP2D6 and CYP2C9 Genes on the Clinical Efficacy of Tramadol and Ketorolac When Using the Accelerated Recovery Protocol in Patients With Uncomplicated Acute Calculous Cholecystitis Who Underwent Cholecystectomy

open access: yesНеотложная медицинская помощь, 2020
Relevance. One of the key components of the accelerated recovery protocols (ARP), in addition to minimizing the surgical approach, is an adequate postoperative analgesia.

CYP2D6 gene polymorphism effect on central hemodynamic parameters in patients with portal hypertension taking propranolol

open access: yesМедицинский совет, 2022
Introduction. Despite the huge number of modern recommendations for the treatment of patients with liver cirrhosis, there is still no clear scheme for prescribing non-selective beta-blockers.Aim. To evaluate effect of polymorphic markers CYP2D6*3, CYP2D6*
