  1. 1. Design and Synthesis of Angiotensin IV Peptidomimetics Targeting the Insulin-Regulated Aminopeptidase (IRAP)

    Författare :Hanna Andersson; Anders Hallberg; Anders Karlén; Federico Corelli; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiotensin IV; AT4; insulin-regulated aminopeptidase IRAP ; inhibitor; peptidomimetics; γ-turn mimetic; macrocycle; Pharmaceutical chemistry; Läkemedelskemi; Medicinal Chemistry; Läkemedelskemi;

    Sammanfattning : Peptidomimetics derived from the bioactive hexapeptide angiotensin IV (Ang IV, Val1-Tyr2-Ile3-His4-Pro5-Phe6) have been designed and synthesized. These peptidomimetics are aimed at inhibiting the insulin-regulated amino peptidase (IRAP), also known as the AT4 receptor. LÄS MER

  2. 2. Design and Synthesis of Malarial Aspartic Protease Inhibitors

    Författare :Karolina Ersmark; Anders Hallberg; Michael Rowley; Uppsala universitet; []

    Sammanfattning : Malaria is one of the major public health problems in the world. Approximately 500 million people are afflicted and almost 3 million people die from the disease each year. Of the four causative species Plasmodium falciparum is the most lethal. LÄS MER

  3. 3. Liquid Crystalline SIloxane Dimers - Advanced Materials with Enhanced Properties

    Författare :Nils Olsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; 45 degree tilt angle; dimer; antiferroelectric; fluorinated; siloxane; polymer; liquid crystal; macrocycle; ferroelectric;

    Sammanfattning : The liquid crystal state is a complex state with many kinds of different molecular attractive and repulsive forces that results in various kinds of phases. Since the pioneering works by Vorländer in the early 20th century, liquid crystal research has to a great extent been depending on careful systematic studies of the structure/property relationships in series of similar liquid crystalline materials.

  4. 4. Studies of Biomimtic Oxidations and Racemizations

    Författare :Gábor Csjernyik; Jan-Erling Bäckvall; Serafino Gladiali; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; oxidation of alcohols; ruthenium; porphyrin; racemization;

    Sammanfattning : This thesis deals with studies of ruthenium-catalyzed hydrogen transfer reactions for oxidations and racemization.Through optimisation of the substrate-selective redox catalyst, the electron and proton transfer mediator (a benzoquinone derivative), and the oxygen-activating metal macrocycle a highly efficient biomimetic oxidation of secondary alcohols was obtained.
