  2. 1. Synthesis of Aldehyde-Functionalized Building Blocks and Their Use for the Cyclization of Peptides : Applications to Angiotensin II

    Author : Petra Johannesson; Rob M. J. Liskamp; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Synthesis; Aldehyde; Cyclization; Peptide; Angiotensin II; Ang II; Bioactive Conformation; Solid Phase Peptide Synthesis; Dimethyl Acetal; Farmaceutisk kemi; Syntes; Aldehyd; Cyklisering; Peptid; Bioaktiv konformation; Fast-fas peptidsyntes; Dimetylacetal; Pharmaceutical chemistry; Farmaceutisk kemi; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

    Abstract : This study addresses the issue of how to convert peptides into drug-like non- peptides with retained biological activities at peptide receptors. Angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe, Ang II) was used as a model peptide. READ MORE

  4. 2. Synthesis, conformational analysis, and biological evaluation of peptides from E. coli P pilus proteins

    Author : Katarina Flemmer Karlsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; CD spectroscopy; peptide structure; ELISA; solid-phase peptide synthesis; peptide; P pili; chaperone; Organic chemistry; Organisk kemi;

    Abstract : Many bacteria utilize hairlike protein appendages (pili) to attach themselves to mucosal cell surfaces in the host organism. The pilus is assembled from protein subunits synthesized inside the bacteria and transported to the outer cell wall for incorporation into the growing pilus. READ MORE

  5. 3. Synthesis and investigation of bacterial effector molecules

    Author : Michael Franz Albers; Christian Hedberg; Christian Hackenberger; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial effectors; organic synthesis; Legionella; PTM; peptide synthesis; nucleotide chemistry; Biorganic Chemistry; bioorganisk kemi;

    Abstract : During infections, bacterial microorganisms initiate profound interactions with mammalian host cells. Usually defense mechanisms of the host destroy intruding bacteria in rapid manner. However, many bacterial pathogens have evolved in a way to avoid these mechanisms. READ MORE

  6. 4. Cell-penetrating peptide targeting mitochondria : Design, synthesis, characterization, and biological effects

    Author : Carmine Pasquale Cerrato; Ülo Langel; Lena Mäler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cell-penetrating peptide; mitochondrial targeting; ROS reduction; mitochondrial membrane potential; antioxidant activity; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : More than twenty years after the discovery of the first cell-penetrating peptide (CPP), a large number of both naturally occurring as well as engineered CPPs have been discovered. Generally, CPPs are short polycationic sequences of less than 30 amino acids that are able to translocate different cargoes into cells. READ MORE

  7. 5. 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
