  1. 1. Developmental neurotoxicity of persistent and non-persistent pollutants : Behavioral and neurochemical assessments of a perfluorinated compound, pesticides and interaction effects

    Författare :Iwa Lee; Henrik Viberg; Per Eriksson; William Mundy; Uppsala universitet; []
    Nyckelord :Brain; Neonatal; Mixtures; Cholinergic system; Organochlorines; Pyrethroids; Organophosphates; Carbamates; Insecticides; PFCs; PFAAs; PFHxS; Endosulfan; Cypermethrin; Chlorpyrifos; Carbaryl; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi;

    Sammanfattning : The focus of this thesis was to investigate developmental neurotoxic effects of different persistent and non-persistent environmental pollutants, alone or in binary mixtures, when exposure occurs during a critical period of brain development, in mice. The compounds investigated included a perfluorinated compound, perfluorohexane sulphonate (PFHxS), and four different pesticides, endosulfan, cypermethrin, chlorpyrifos and carbaryl. LÄS MER

  3. 2. Ligands of the Angiotensin II Type 2 Receptor : Exploring structure and function of the AT2R ligand C38

    Författare :Rebecka Isaksson; Mats Larhed; Annette Bayer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiotensin II type 2 receptor; AT2R antagonists; sulfonyl carbamates; bicyclic amides; metabolic stability; functional activity assay; pharmacological profile; medicinal chemistry; structure-activity relationship; Medicinal Chemistry; Läkemedelskemi;

    Sammanfattning : The renin-angiotensin-aldosterone-system (RAAS) control blood-pressure regulation, exerted by the main effector peptide angiotensin II (AngII) binding the angiotensin II type 1 receptor (AT1R). While hypertension is the most known disease caused by over-activity in RAAS, several proteins in the system exhibit protective functions. LÄS MER

    Sammanfattning : Section 1 of this thesis contains an introduction to method development in organic synthesis, multicomponent reactions, sulfonyl azides, tracer development in 11C chemistry and the biological target.Section 2 describes the use of sulfonyl azides in carbonylative chemistry. Paper I covers development of a diazotransfer protocol. LÄS MER

  7. 5. Amidst the green Metal-catalyzed amide formation from carboxylic acids

    Författare :Helena Lundberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes novel methods for transition metal-catalyzed transformation of non-activated carboxylic acids to amides. It was found that 2-10 mol% of zirconium(IV) chloride or 10-20 mol% titanium(IV) isopropoxide catalyzed the formation of a range of secondary and tertiary amides in good to excellent yields (61-99%) in THF at 70-100°C, with molecular sieves present as water scavengers.
