  2. 11. Computational prediction of ligand binding in peptide G-protein coupled receptors

    Author : Silvana Vasile; Hugo Gutiérrez-de-Terán; Johan Åqvist; Herman Van Vlijmen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GPCR; neuropeptide Y; angiotensin II receptor; molecular dynamics; free energy perturbation; homology modelling; computer simulations; peptide binding; peptidomimetics; binding free energy.;

    Abstract : G-protein coupled receptors (GPCRs) are a superfamily of membrane receptors involved in a wide variety of biological processes, and their malfunction is associated with many diseases. Consequently, GPCRs are targeted by one-third of the drugs on the market, and constitute the focus of active public and private research in the search of more effective drugs. READ MORE

  4. 12. Development of 2-Pyridone-based central fragments : Affecting the aggregation of amyloid proteins

    Author : Magnus Sellstedt; Fredrik Almqvist; Petri Pihko; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 2-pyridone; central fragment alteration; multi-component reactions; directed diversity-oriented synthesis; peptidomimetics; amyloid; protein aggregation; pilicide; curlicide; Biorganic Chemistry; bioorganisk kemi;

    Abstract : There are many applications of small organic compounds, e.g. as drugs or as tools to study biological systems. Once a compound with interesting biological activity has been found, medicinal chemists typically synthesize small libraries of compounds with systematic differences to the initial “hit” compound.

  5. 13. Design and synthesis of -turn peptidomimetics : Applications to angiotensin II

    Author : Susanna Lindman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; peptide synthesis; turn mimetics; molecular modelling; receptor binding affinity; Farmaceutisk kemi; 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 while retaining the biological activity at peptide receptors. Angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe, Ang II) was used as a model peptide. Small bioactive peptides are in most cases conformationally flexible molecules. READ MORE

  6. 14. Photoswitchable Peptidomimetics : Synthesis and Photomodulation of Functional Peptides

    Author : Miranda Varedian; Adolf Gogoll; Morten Grøtli; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; β-hairpin; peptidomimetics; stilbene; thioaurone; photochemistry; Organic chemistry; Organisk kemi;

    Abstract : The secondary structure of peptides is of pivotal importance for their biological function. The introduction of photoswitchable moieties into the backbones of peptides provides a unique way of regulating their conformation using an external stimulus, i.e., light. READ MORE

  7. 15. Characterization of HCV Protease Inhibitors : Inhibition and Interaction Studies with Applications for Drug Discovery

    Author : Sofia Svahn Gustafsson; U. Helena Danielson; Johan Neyts; Uppsala universitet; []
    Keywords : Biokemi; Biochemistry;

    Abstract : In this thesis, different approaches based on inhibition and interactions studies, have been used to characterize inhibitors of the non-structural protein 3 (NS3) from the hepatitis C virus (HCV). This involves identification of enzyme inhibitory effects and characterization of interaction mechanisms and kinetics, as well as effects on replication in a cell based system and serum protein binding.
