  1. 11. Microwave-Assisted Synthesis of C2-Symmetric HIV-1 Protease Inhibitors : Development and Applications of In Situ Carbonylations and other Palladium(0)-Catalyzed Reactions

    Författare :Johan Wannberg; Anders Hallberg; David C. Rees; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; HIV; protease inhibitors; palladium; carbonylations; molybdenum hexacarbonyl; dihydropyrimidone; DHPM; microwave; cross-coupling; diazylhydrazines; carbon monoxide; synthesis; C2-symmetric; HIV-1 protease inhibitors; aminocarbonylation; fluorous; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

    Sammanfattning : The HIV protease is an essential enzyme for HIV replication and constitutes an important target in the treatment of HIV/AIDS. Efficient combination therapies using inhibitors of the reverse transcriptase and protease enzymes have led many to reevaluate HIV infections from a terminal condition to a chronic-but-manageable disease in the developed world.

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

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

    Sammanfattning : 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. LÄS MER

  3. 13. Computational Studies of HIV-1 Protease Inhibitors

    Författare :Wesley Schaal; Garland Marshall; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; HIV Protease; 3D-QSAR; CoMFA; Molecular Modelling; Force Field Parameterization; Quantum Mechanics; DFT; Enzyme Kinetics; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Organic Pharmaceutical Chemistry; Organisk farmaceutisk kemi;

    Sammanfattning : Human Immunodeficiency Virus (HIV) is the causative agent of the pandemic disease Acquired Immune Deficiency Syndrome (AIDS). HIV acts to disrupt the immune system which makes the body susceptible to opportunistic infections. Untreated, AIDS is generally fatal. LÄS MER

  4. 14. Identification of protease inhibitors against Flaviviruses and Coronaviruses

    Författare :Dario Akaberi; Åke Lundkvist; Johan Lennerstrand; Josef D. Järhult; Ujjwal Neogi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antiviral research; protease inhibitors; flaviviruses; coronaviruses; ZIKV; TBEV; SARS-CoV-2;

    Sammanfattning : Vector-borne flaviviruses and coronaviruses of zoonotic origins are important human pathogens and represent a serious threat to public health worldwide. Flaviviruses can be found on all continents, apart from Antarctica, where they are transmitted by arthropod vectors causing millions of infections every year. LÄS MER

  5. 15. Functional and structural studies of the Presequence protease, PreP

    Författare :Hans G Bäckman; Elzbieta Glaser; Per Gardeström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Presequence Protease; PreP; AtPreP; hPreP; Biochemistry; biokemi;

    Sammanfattning : AtPreP (Arabidopsis thaliana Presequence Protease) is a zink metallooligopeptidase that is dually targeted to both mitochondria and chloroplasts. In these organelles it functions as a peptidasome that degrades the N-terminal targeting peptides that are cleaved off from the mature protein after protein import, as well as other unstructured peptides.
