  1. 1. Computational Modeling of Macrocycles and Structure-Based Design of Novel Antibacterial Compounds

    Author : Gustav Olanders; Anders Karlén; Peter Brandt; Christian Sköld; Dan Sindhikara; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; macrocycles; docking; conformational sampling; conformational prefer-ences; antibiotics;

    Abstract : The integration of computational methods into the drug discovery process provides valuable tools to help advance new and improved drugs into the clinic. As medicinal chemists explore novel targets and new areas of chemical space, our computational toolkit must also evolve. READ MORE

  2. 2. Computational Studies of Macrocycles and Molecular Modeling of Hepatitis C Virus NS3 Protease Inhibitors

    Author : Hiba Alogheli; Anders Karlén; Anja Sandström; Peter Brandt; Leif Eriksson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drug discovery; HCV NS3 protease; macrocycles; conformational analysis; docking.; Medicinal Chemistry; Läkemedelskemi;

    Abstract : Computational tools are utilized in the drug discovery process to discover, design, and optimize new therapeutics. One important approach is structure-based drug design which relies on knowledge about the 3D structure of the biological target. READ MORE

  3. 3. The solution conformations of macrocycles. Applications in the exploration of weak interactions and in drug development

    Author : Emma Danelius; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Macrocycles; cyclic peptides; NMR; solution conformational analysis; NAMFIS; β-hairpin; weak interactions; halogen bonding; protein-protein interaction; bioactive conformation; macrolides; cell permeable conformation.;

    Abstract : Understanding the solution conformation and dynamics of molecules with biological relevance, as well as the impact of their conformation stabilizing weak interactions, is for example important for drug design. Macrocycles have attractive pharmaceutical properties, and are of special interest as drug leads for targets with large, flat and featureless binding sites like protein-protein interfaces. READ MORE

  4. 4. Flexible Synthesis of Rigid Cyclophanes - Synthesis and derivatisation of 2,7-diaza-1,2,3,6,7,8-hexahydropyrene into chiral macrocycles

    Author : Jörgen Toftered; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Macromolecular chemistry; Makromolekylär kemi; biomimetic; cross-linking; thiourea; urea; difluorodinitrobenzene; cyclodimerisation; Cyclophanes; macrocycles;

    Abstract : Rigid, chiral and amphiphilic cyclophanes of potential use as biomimetic host molecules were prepared by cyclic dimerisation of chiral diamino building blocks with amino-reactive cross-linking reagents. A reliable synthesis of the scaffold 2,7-diaza-1,2,3,6,7,8-hexahydropyrene was developed. READ MORE

  5. 5. Macrocyclic Carbohydrate/Amino Acid Hybrid Molecules - Synthesis and Evaluation as Artificial Receptors

    Author : Johan Billing; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3-dipolar cycloaddition; 3-triazoles; 2; 1; molecular recognition; artificial receptors; sugar amino acids; cyclic peptides; macrocycles; Organic chemistry; Organisk kemi;

    Abstract : Methods were developed for the synthesis of three different types of macrocyclic carbohydrate/amino acid hybrid molecules. In the synthesis of the first type of macrocycles, a glucosamine derivative was oxidized at C6 and the obtained sugar amino acid was coupled to tripeptides. READ MORE
