Pharmacokinetics of panobinostat: Inter-species difference in metabolic stability [Metabolism, Transport, and Pharmacogenetics]

ASPET

The objective of this study was to examine the in vitro metabolic stability of panobinostat in different matrices and assess the influence of that metabolic stability on the in vivo pharmacokinetics and CNS delivery of panobinostat.

Preclinical systemic pharmacokinetics, dose-proportionality, and CNS distribution of the ATM inhibitor WSD0628, a novel radiosensitizer for the treatment of brain tumors [Metabolism, Transport, and Pharmacogenetics]

ASPET

Efficacy of radiosensitizers for brain tumors may be influenced by a lack of effective drug delivery across the blood-brain barrier (BBB). The objective of this study was to evaluate the systemic pharmacokinetics and mechanisms that influence the CNS distribution of WSD0628, a novel and potent ATM inhibitor, in the mouse.

Central Nervous System Distributional Kinetics of Selected Histone Deacetylase Inhibitors [Metabolism, Transport, and Pharmacogenetics]

ASPET

This lack of activity could be due to insufficient CNS exposure to the unbound drug. In this study, we investigated the systemic pharmacokinetics and subsequent CNS distribution of two potent HDACIs, vorinostat and quisinostat, in the murine model.

A Pilot Study to Assess the Suitability of Riboflavin as A Surrogate Marker of Breast Cancer Resistance Protein (BCRP) in Healthy Participants [Metabolism, Transport, and Pharmacogenetics]

ASPET

First, we assessed the substrate potential of riboflavin towards other major drug transporters using established transfected cell systems. Overall, these data indicate that plasma riboflavin is a promising biomarker of BCRP that may offer a possibility to assess drug candidate as a BCRP modulator in early drug development.

Significance of organic anion transporter 2 and organic cation transporter 2 in creatinine clearance: Mechanistic evaluation using freshly-prepared human primary renal proximal tubule cells [Metabolism, Transport, and Pharmacogenetics]

ASPET

Quantitative pharmacokinetic models should therefore focus on OCT2/MATE when describing serum creatinine and creatinine clearance modulation by inhibitor drugs and genotype- or disease-related activity changes.

An Integrative Approach to Elucidate Mechanisms Underlying the Pharmacokinetic Goldenseal-Midazolam Interaction: Application of In Vitro Assays and Physiologically Based Pharmacokinetic Models to Understand Clinical Observations [Metabolism, Transport, and Pharmacogenetics]

ASPET

The objective of this study was to mechanistically assess the pharmacokinetic goldenseal-midazolam interaction using an integrated in vitro - in vivo - in silico approach. min -1 , respectively). The objective of the current work was to evaluate fundamental mechanisms underlying the clinically observed goldenseal-midazolam interaction.
