  1. 1. Structure-Based Design and Synthesis of Protease Inhibitors Using Cycloalkenes as Proline Bioisosteres and Combinatorial Syntheses of a Targeted Library

    Author : Fredrik Thorstensson; Ingemar Kvarnström; Charles Hedgecock; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic chemistry; organic synthesis; combinatorial synthesis; metathesis; olefin metathesis; thrombin; HCV; NS3; protease; proline isosteres; inhibitor; Organic synthesis; Organisk syntes;

    Abstract : Structure-based drug design and combinatorial chemistry play important roles in the search for new drugs, and both these elements of medicinal chemistry were included in the present studies. This thesis outlines the synthesis of protease inhibitors against thrombin and the HCV NS3 protease, as well as the synthesis of a combinatorial library using solid phase chemistry. READ MORE

  2. 2. Peptidomimetic Enzyme Inhibitors : Targeting M. tuberculosis Ribonucleotide Reductase and Hepatitis C Virus NS3 Protease

    Author : Johanna Nurbo; Anders Hallberg; Anders Karlén; Anja Sandström; Per Arvidsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enzyme inhibitor; peptidomimetics; structure-activity relationship; tuberculosis; ribonucleotide reductase; hepatitis C virus; NS3 protease; Pharmaceutical chemistry; Farmaceutisk kemi; Medicinal Chemistry; Läkemedelskemi;

    Abstract : This thesis focuses on the design and synthesis of inhibitors targeting Mycobacterium tuberculosis ribonucleotide reductase (RNR) and hepatitis C virus (HCV) NS3 protease; enzymes that have been identified as potential drug targets for the treatment of tuberculosis and hepatitis C, respectively. Small peptides have been recognized as inhibitors of these enzymes. READ MORE

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

    Author : Anna Karin Belfrage; Anja Sandström; Ulf Ellervik; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. On the Design and Synthesis of Hepatitis C Virus NS3 Protease Inhibitors : From Tripeptides to Achiral Compounds

    Author : Pernilla Örtqvist; Anja Sandström; Mats Larhed; Anders Hallberg; Morten Grøtli; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hepatitis C virus; NS3 protease inhibitor; structure-activity relationship; resistance; 2 1H -pyrazinone; phenylglycine; Pharmaceutical chemistry; Farmaceutisk kemi; Medicinal Chemistry; Läkemedelskemi;

    Abstract : Infection by the hepatitis C virus (HCV) leads to inflammation of the liver, i.e. hepatitis. The acute infection often progresses to a chronic phase during which the liver function is gradually impaired. READ MORE

  5. 5. Design and Synthesis of Hepatitis C Virus NS3 Protease Inhibitors Incorporating a P2 Cyclopentane-Derived Scaffold

    Author : Marcus Bäck; Anja Sandström; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HCV; NS3 protease; Proline mimic; Cyclopentane-derived scaffold; Linear inhibitors; Macrocyclic inhibitors; Organic synthesis; Organisk syntes;

    Abstract : This thesis describes the design, synthesis and structure-activity relationships analysis of potential inhibitors targeting the hepatitis C virus (HCV) NS3 protease. Also discussed is the disease caused by HCV infection and the class of enzymes known as proteases. READ MORE
