  1. 1. 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

  2. 2. Pericyte Influence on Drug Delivery Across the Blood-Brain Barrier Implications for Therapy of Neurodegenerative Diseases

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Nebojsa Mihajlica; Uppsala universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; pericytes; pericyte-deficiency; pharmacokinetics; small-molecular drugs; drug distribution; transporters; P-glycoprotein; tyrosine kinase inhibitors; Farmakokinetik och läkemedelsterapi; Pharmacokinetics and Drug Therapy;

    Abstract : The blood-brain barrier (BBB) represents a complex interface between the brain parenchyma and systemic blood circulation, strictly controlling exchange of substances between the two sites. Pericytes are mural cells located on the abluminal membrane of the brain endothelium, involved in BBB formation and maintenance. READ MORE

  3. 3. 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

  4. 4. Computational and Experimental Models for the Prediction of Intestinal Drug Solubility and Absorption

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Christel A. S. Bergström; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; aqueous drug solubility; melting point; intestinal drug permeability; pH-dependent solubility; multivariate data analysis; molecular descriptors; molecular surface area; in silico modeling; drug absorption; Galenisk farmaci; PHARMACY Pharmaceutics; FARMACI Galenisk farmaci;

    Abstract : New effective experimental techniques in medicinal chemistry and pharmacology have resulted in a vast increase in the number of pharmacologically interesting compounds. However, the number of new drugs undergoing clinical trial has not augmented at the same pace, which in part has been attributed to poor absorption of the compounds. READ MORE

  5. 5. In vitro and in silico prediction of drug-drug interactions with transport proteins

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gustav Ahlin; Uppsala universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Solute carrier; SLC transporter; OCT1; Organic cation transporter 1; SLC22A1; OATP1B1; SLCO1B1; Organic anion transporting peptide 1B1; Drug transport; Active transport; Genetic polymorphism; Cell lines; Gene expression; Multivariate data analysis; OPLS; PHARMACY Pharmaceutics; FARMACI Galenisk farmaci; PHARMACY Biopharmacy; FARMACI Biofarmaci; galenisk farmaci; Pharmaceutics; Biopharmaceutics; biofarmaci;

    Abstract : Drug transport across cells and cell membranes in the human body is crucial for the pharmacological effect of drugs. Active transport governed by transport proteins plays an important role in this process. A vast number of transport proteins with a wide tissue distribution have been identified during the last 15 years. READ MORE
