2. 1. Lipid-based liquid crystals as drug delivery vehicles for antimicrobial peptides

   Author : Lukas Boge; Martin Andersson; Lovisa Ringstad; RISE; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Liquid crystals; liquid crystalline nanoparticles; cubosome; hexosome; phase behavior; antimicrobial peptide; AMP; glycerol monooleate; proteolysis; antimicrobial effect; antimicrobial resistance; bacterial membrane; membrane interaction; infection; topical delivery; pulmonary delivery;

   Abstract : The development of antimicrobial resistance is a great challenge within health sectors worldwide. Thus, demand for new, efficient treatments is urgent in order to treat various bacterial infections. Antimicrobial peptides (AMPs) are a group of antibiotics that have gained more and more attraction in the past decade. READ MORE

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

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

   Abstract : 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. READ MORE

5. 3. Development of antimicrobial peptides : Methodological aspects, design, synthesis and evaluation of a new class of antimicrobial peptides

   Author : Marie Danielsson; Anders Undén; Maria Kempe; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Abstract : A new protective group for the indole nitrogen of the amino acid tryptophan, the Boc-sarcosinoyl-sarcosinolyl (Boc-Sar-Sar) is described. This protective group shows good stability to the reaction conditions used in solid phase peptide synthesis and can be incorporated into the peptide as Fmoc-Trp(Boc-Sar-Sar)-OH. READ MORE

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

   Author : Taj Muhammad; Ulf Göransson; Sunithi Gunasekera; Adam A. Strömstedt; Wang Guangshun; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 5. Antimicrobial peptide therapy for tuberculosis infections

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

   Abstract : 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. READ MORE
