  1. 11. Design and Synthesis of Inhibitors Targeting the Hepatitis C Virus NS3 Serine Protease and the Aspartic Protease BACE-1

    Author : Marcus Bäck; Ingemar Kvarnström; Stephen Hanessian; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis describes the synthesis of molecules designed to inhibit the hepatitis C virus (HCV) NS3 serine protease and the human aspartic protease BACE-1, and it also reports the structure-activity relationships between potential inhibitors and the targeted enzymes. In addition, consideration is given to the class of enzymes known as proteases, as well as the question of why such enzymes can be regarded as suitable targets for developing drugs to combat diseases in general.

  2. 12. Design and Synthesis of BACE-1 Inhibitors : Novel Compounds Targeting an Aspartic Protease Important in the Pathogenesis of Alzheimer’s Disease

    Author : Catarina Björklund; Bertil Samuelsson; Rolf Johansson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis deals with the design and synthesis of protease inhibitors targeting the aspartic protease BACE-1 (β-site APP cleaving enzyme-1), an enzyme important in the pathogenesis of Alzheimer’s disease. The inhibitors are evaluated with respect to inhibition data, in a structure-activity relationship part. READ MORE

  3. 13. Design and Synthesis of Inhibitors Targeting BACE-1, an Aspartic Protease Involved in the Pathogenesis of Alzheimer’s Disease

    Author : Veronica Sandgren; Ingemar Kvarnström; Bertil Samuelsson; Thomas Olsson; Linköpings universitet; []
    Keywords : ;

    Abstract : Alzheimer’s disease (AD) is the most common form of dementia, occurring in an estimated 24 million people worldwide. Accumulation of amyloid-b peptides leads to development of plaques in the brain, which eventually stimulates hyperphosphorylation of tau proteins leading to tangles. This is believed to play a crucial role in the pathology of AD. READ MORE

  4. 14. Development of a protein-free fed-batch process for NS0 cells: studies on regulation of proliferation

    Author : Erika Spens; Lena Häggström; Jean-Louis Goergen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NS0 myeloma cells; protein-free medium; fed-batch; conditioned medium; autocrine growth factors; abortive proliferation; protease activity; aprotinin; gp130; Bioengineering; Bioteknik;

    Abstract : The overall objective of this study was to investigate how NS0 cell proliferation is regulated in protein-free media. The hypothesis was that during the adaptation to growth factor-free media, animal cell lines start to produce their own autocrine growth factors to support proliferation, and after some time in a culture the effects of these factors are lost which results in cessation of proliferation.

  5. 15. Design, Synthesis, and Structure-Activity Relationships Analysis of Potential Inhibitors of the Serine Protease Thrombin and the Malarial Aspartic Proteases Plasmepsin I and II

    Author : Anders Dahlgren; Thomas Olsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The design, synthesis, and structure-activity relationships analysis of some potential protease inhibitors are outlined in this thesis. In particular, the serine protease thrombin and the malarial aspartic proteases plasmepsin I and II (Plm I and II) are described in regard to the roles they play in living organisms, and that is followed by discussions concerning the design, synthesis, and biological test results of inhibitors of these enzymes.
