  2. 1. Studies of Retroviral Reverse Transcriptase and Flaviviral Protease Enzymes as Antiviral Drug Targets : Applications in Antiviral Drug Discovery & Therapy

    Author : Muhammad Junaid; Jarl ES Wikberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virus; enzymes; HIV AIDS; retroviral reverse transcriptase; flaviviral protease; NRTIs; proteochemometrics; drug resistance; DEN; JEV; NS2B H -NS3pro; antiviral; drug targets; drug discovery; drug therapy.; Farmakologi; Pharmacology;

    Abstract : Viruses are a major threat to humans due to their unique adaptability, evolvability and  capability to control their hosts as parasites and genetic elements. HIV/AIDS is the third largest cause of death by infectious diseases in the world, and drug resistance due to the viral mutations is still the leading cause of treatment failure. READ MORE

  4. 2. Tethered Lipid Vesicles as Nanoscale Sensor Elements

    Author : Seyed Tabaei; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aquaglyceroporin; lipid vesicles; total internal reflection fluorescence TIRF microscopy; cell membrane; aquaporin; pore formation; surface plasmon resonance SPR ; phospholipase A2; antiviral peptide; lipid bilayer; biosensing; microfluidics;

    Abstract : The primary aim of this thesis work has been to explore and advance the potential of surface tethered lipid vesicles as a platform for studying in particular the following three biomembrane-related processes: trans-membrane transport, membrane-peptide interactions and the activity of membrane active enzymes. First, a method based on surface plasmon resonance (SPR) spectroscopy was developed for studying passive diffusion processes as well as the membrane-protein mediated transport of small non electrolyte molecules across lipid bilayers.

  5. 3. Biosensor Studies of Ligand Interactions with Structurally Flexible Enzymes : Applications for Antiviral Drug Development

    Author : Matthis Geitmann; U. Helena Danielson; Marc H. V. van Regenmortel; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; SPR biosensor; HIV-1 reverse transcriptase; HCMV protease; interaction kinetics; drug discovery; non-nucleoside inhibitor; resistance; Biokemi; Biochemistry; Biokemi;

    Abstract : The use of a surface plasmon biosensor fills a missing link in kinetic studies of enzymes, since it measures directly the interaction between biomolecules and allows determination of parameters that are determined only indirectly in activity assays. The present thesis deals with kinetic and dynamic aspects of ligand binding to two viral enzymes: the human cytomegalovirus (HCMV) protease and the human immunodeficiency virus type 1 reverse transcriptase (HIV-1 RT).

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

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

    Abstract : 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. READ MORE

  7. 5. Effect of the tri-peptide glycyl-prolyl-glycine amide on HIV-1 replication

    Author : Jin Su; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV-1; antiretrovirals; peptides; tri-peptides; GPG-NH2; capsid formation; p24 dimerization; coneshaped core; GPG motif; V3 loop; infectivity;

    Abstract : The human immunodeficiency virus type 1 (HIV-1) is the etiological agent responsible for AIDS worldwide. The aim of this thesis was to evaluate the anti-HIV-1 activity of short peptides and to investigate their mode of inhibition. READ MORE
