  1. 6. LL-37-derived cyclic antimicrobial drug leads : Design, synthesis, activity and different ways of creating them 

    Författare :Taj Muhammad; Ulf Göransson; Sunithi Gunasekera; Adam A. Strömstedt; Wang Guangshun; Uppsala universitet; []
    Nyckelord :antimicrobial peptide; host defense; antimicrobial; LL-37; KR-12; peptide cyclisation; peptide dimerisation; croos-linking; cyanobactin-macrocyclase; PatGmac; butelase 1; enzymatic cyclisation; immobilisation; Farmakognosi; Pharmacognosy;

    Sammanfattning : In an era where last-line antibiotics are failing, one of the powerful approaches to develop novel therapeutic agents is to turn back to nature in order to identify possible drug candidates. Among the potential candidates, antimicrobial peptides (AMPs) have garnered much attention as an antimicrobial. LÄS MER

  3. 7. Amphiphilic Peptide Interactions with Complex Biological Membranes : Effect of peptide properties on antimicrobial and anti-inflammatory effects

    Författare :Shalini Singh; Martin Malmsten; Per Hansson; Debora Berti; Uppsala universitet; []
    Nyckelord :LPS; Antimicrobial; Peptide; Inflammation; Infections; Liposome; Binding; PEG; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Sammanfattning : With increasing problem of resistance development in bacteria against conventional antibiotics, as well as problems associated with diseases either triggered or enhanced by infection, there is an urgent need to identify new types of effective therapeutics for the treatment of infectious diseases and its consequences. Antimicrobial and anti-inflammatory peptides have attracted considerable interest as potential new antibiotics in this context. LÄS MER

  4. 8. Mechanisms and Biological Costs of Bacterial Resistance to Antimicrobial Peptides

    Författare :Hava Lofton Tomenius; Dan I Andersson; Ørjan Samuelsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; antibiotic resistance; fitness cost; Salmonella Typhimurium; Staphylococcus aureus; bile; serum; pH response; growth rate; mice; phoP; pmrB; waaY; LPS; LL-37; defensins; membrane potential; Mikrobiologi; Microbiology;

    Sammanfattning : The global increasing problem of antibiotic resistance necessarily drives the pursuit and discovery of new antimicrobial agents. Antimicrobial peptides (AMPs) initially seemed like promising new drug candidates. Already members of the innate immune system, it was assumed that they would be bioactive and non-toxic. LÄS MER

  5. 9. Bacterial Resistance to Antimicrobial Peptides : Rates, Mechanisms and Fitness Effects

    Författare :Maria Pränting; Dan Andersson; Ian Chopra; Uppsala universitet; []
    Nyckelord :antimicrobial peptides; antibiotic resistance; fitness cost; bacterial evolution; small colony variants; cyclotides; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology; Mikrobiologi; Microbiology;

    Sammanfattning : The rapid emergence of bacterial resistance to antibiotics has necessitated the development of alternative treatment strategies. Antimicrobial peptides (AMPs) are important immune system components that kill microbes rapidly and have broad activity-spectra, making them promising leads for new pharmaceuticals. LÄS MER

  7. 10. Antimicrobial peptide therapy for tuberculosis infections

    Författare :Komal Umashankar Rao; Medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tuberculosis; antimicrobial peptides; mode of action; nanoparticles; novel therapy; membrane active peptides;

    Sammanfattning : Tuberculosis is a communicable disease that persists as a second leading cause for death, by an infectious agent. Several reasons contribute to this issue to this, of which an upsurge in antibiotic resistance is of top concern. Resistance patterns in the form of mono or multidrug resistance was reported to most clinical therapies at our disposal. LÄS MER
