1. 1. Haematopoietic Serine Proteases : A Cleavage Specificity Analysis

   Författare :Michael Thorpe; Lars Hellman; Urban Gullberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mast cell; cleavage specificity; phage display; chymase; serine protease; granzyme; fish protease;

   Sammanfattning : Mast cells are innate immune cells, historically involved in allergy responses involving IgE. Through this, they have earned a reputation as a fairly detrimental cell type. Their beneficial roles remain somewhat enigmatic although they clearly have the ability to modulate the immune system. LÄS MER

3. 2. Design and Synthesis of Serine and Aspartic Protease Inhibitors

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

   Sammanfattning : 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. LÄS MER

4. 3. Characterization of conjugated protease inhibitors

   Författare :Erika Billinger; Gunnar Johansson; Boris Turk; Uppsala universitet; []
   Nyckelord :Serine protease inhibitors; conjugation; immobilization; leupeptin analogues; potato serine protease inhibitor; soluble carriers; inorganic carriers.; Biokemi; Biochemistry;

   Sammanfattning : The overall theme of this thesis is a step by step approach for the design and characterization of conjugated protease inhibitors. This involves both a new assay method for protease activity and protease inhibition (paper I), a study of the stoichiometry for protease inhibitor interaction (paper II), design of inhibitory peptides (paper IV) and the construction of inhibitor conjugates (paper III & IV).

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

   Författare :Fredrik Wångsell; Mats Larhed; Jari Yli-Kauhaluoma; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER
