  1. 1. Intracellular unbound drug concentrations Methodology and application for understanding cellular drug exposure

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : André Mateus; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracellular unbound drug concentrations; free drug; drug binding; drug transport; drug accumulation; cellular drug response; drug target engagement; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : Most known drug targets and metabolizing enzymes are located inside cells. Interactions with these proteins are determined by intracellular unbound drug concentrations. Assessing intracellular drug exposure is technically challenging, but essential for predicting pharmacokinetic, pharmacological, and toxicological profiles of new drugs. READ MORE

  2. 2. Characterization of parameters influencing intracellular bioavailability and prediction of intracellular drug exposure

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andrea Treyer; Uppsala universitet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracellular drug bioavailability; unbound drug concentration; drug disposition; ADME; drug transport; drug metabolism membrane partitioning; phospholipid; drug-drug interaction; antisense oligonucleotide; cell-penetrating peptide; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : This thesis work investigates factors influencing intracellular drug disposition. An experimental method for measurement of intracellular bioavailability (Fic), was used throughout. Fic is defined as the ratio between the unbound drug concentration inside the cell and the compound concentration in the cell exterior. READ MORE

  3. 3. In Vivo Active Drug Uptake and Efflux at the Blood-Brain Barrier With Focus on Drug Transport Interactions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Muhammad Waqas Sadiq; Uppsala universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; Active uptake transport; Microdialysis; P-glycoprotein; Drug interactions; Species differences; Pharmacokinetics; Pharmacodynamics; NONMEM; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : The blood-brain barrier (BBB) controls the movement of substances into and out of the brain. The tight junctions between endothelial cells and energy dependent transporters in the BBB influence rate and extent of drug distribution to the brain. READ MORE

  4. 4. Development of Methods for Assessing Unbound Drug Exposure in the Brain In vivo, in vitro and in silico

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Markus Fridén; Uppsala universitet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; Drug transport; Tissue distribution; Transporters; Pharmacokinetics; PHARMACY Other pharmacy; FARMACI Övrig farmaci; PHARMACY Biopharmacy; FARMACI Biofarmaci; PHARMACY Pharmaceutical pharmacology; FARMACI Farmaceutisk farmakologi; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Abstract : The blood-brain barrier is formed by tightly joined capillary cells with transporter proteins and acts as to regulate the brain concentration of nutrients as well as many drugs. When developing central nervous system drugs it is necessary to measure the unbound drug concentration in the brain, i.e. the unbound brain exposure. READ MORE

  5. 5. Developmental Aspects of Drug Transport Across the Blood-Brain Barrier

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jörgen Bengtsson; Uppsala universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; development; active transport; tight junction proteins; microdialysis; recovery; morphine; nitrofurantoin; Bcrp; microarray; real-time PCR; in vitro; in vivo; LC-MS MS; PHARMACY Biopharmacy; FARMACI Biofarmaci; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Abstract : The developmental aspect of drug transport across the blood-brain barrier (BBB) was investigated. Microdialysis was used to study unbound morphine BBB transport at different ages in sheep. An in vitro study was performed to find differentially expressed genes in brain capillary-rich fractions of the brain in rats of different ages. READ MORE
