1. 1. Lipid-based liquid crystals as drug delivery vehicles for antimicrobial peptides

   Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

   Författare :Lukas Boge; [2017]
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hexosome; antimicrobial peptide; cubosome; proteolysis; AMP; liquid crystalline nanoparticles; glycerol monooleate; Liquid crystals;

   Sammanfattning : The development of antimicrobial resistance is a great challenge within the health sector around the world. The demand for new efficient treatments is alarming in order to treat various bacterial infections in the near future. Antimicrobial peptides (AMPs) are a group of novel antibiotics that have gain more and more attraction the past decade. LÄS MER

   Sammanfattning : In this work, the solubility of butyl paraben in 7 pure solvents and in 5 different ethanol-water mixtures has been determined from 1 ˚C to 50 ˚C. The solubility of ethyl paraben and propyl paraben in various solvents has been determined at 10 ˚C. LÄS MER

5. 4. Investigation of the functionality related characteristics of hydroxypropyl methylcellulose for the release from matrix tablets

   Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

   Författare :Anna Viridén; [2011]
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; functionality related characteristics; batch-to-batch variation; hydrophilic matrix tablets; hydroxypropyl methylcellulose; polymer characterisation; heterogeneous; drug release;

   Sammanfattning : Hydrophilic matrix tablets are a compressed well mixed composite of drug substance and excipients including a hydrophilic polymer. When the tablet comes in contact with biological fluids, the hydrophilic polymer starts to dissolve, a process that decreases the water penetration through the tablet and involves dimensional changes of the tablet due to swelling of the solvated polymers.

7. 5. Design and Synthesis of Hepatitis C Virus NS3 Protease Inhibitors Targeting Different Genotypes and Drug-Resistant Variants

   Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

   Författare :Anna Karin Belfrage; Anja Sandström; Ulf Ellervik; [2015]
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hepatitis C virus; HCV; NS3 protease inhibitors; structure-activity relationship; 2 1H -pyrazinone; quinazoline; resistance; Pd catalysis; Medicinal Chemistry; Läkemedelskemi; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : Since the first approved hepatitis C virus (HCV) NS3 protease inhibitors in 2011, numerous direct acting antivirals (DAAs) have reached late stages of clinical trials. Today, several combination therapies, based on different DAAs, with or without the need of pegylated interferon-α injection, are available for chronic HCV infections. LÄS MER
