  1. 1. Design and Synthesis of Serine and Aspartic Protease Inhibitors

    Author : Fredrik Wångsell; Ingemar Kvarnström; Olle Karlsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic chemistry; organic synthesis; metathesis; HCV; NS3; protease; proline isosteres; inhibitor; aspartic protease inhibitors; hydroxyethylene; Organic synthesis; Organisk syntes;

    Abstract : This thesis describes the design and synthesis of compounds that areintended to inhibit serine and aspartic proteases. The first part of the text deals with preparation of inhibitors of the hepatitis C virus (HCV) NS3 serine protease. Hepatitis C is predominantly a chronic disease that afflicts about 170 million people worldwide. READ MORE

  2. 2. 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

  3. 3. Design and Synthesis of Aspartic and Serine Protease Inhibitors : Targeting the BACE-1 and the HCV NS3 Protease

    Author : Fredrik Wångsell; Mats Larhed; Jari Yli-Kauhaluoma; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; BACE-1; transition state mimetic; tertiary hydroxyl group; hydroxyethylene; statine; hydroxyethylamine; hepatitis C; HCV NS3; bioisostere; protease inhibitor.; Pharmaceutical chemistry; Läkemedelskemi; Medicinal Chemistry; Läkemedelskemi;

    Abstract : This thesis describes work done to design and synthesize protease inhibitors, with the intention of developing therapeutic agents for Alzheimer’s disease (AD) and the chronic liver condition caused by infection of the hepatitis C virus (HCV). AD is the most common form of dementia, and HCV infection is the primary reason for liver transplantation in industrialized countries. READ MORE

  4. 4. Peptide-Based Inhibitors of Hepatitis C Virus NS3 Serine Protease: Kinetic Aspects and Inhibitor Design

    Author : Anton Poliakov; Helena Danielson; Boris Turk; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; serine protease; inhibitor; slow-binding; protein purification; Biokemi; Biochemistry; Biokemi;

    Abstract : Hepatitis C is a serious disease that affects about 200 million people worldwide. No anti-HCV vaccine or specific anti-viral drugs are available today. Non-structural protein 3 (NS3) of HCV is a bifunctional serine protease/helicase, and the protease has become a prime target in the search for anti-HCV drugs. READ MORE

  5. 5. 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
