  1. 1. Separation of Glycoproteins using Shielding Boronate Affinity Chromatography

    Författare :YuCai Li; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affinity chromatography; boronate; chymotrypsin; haemoglobin; mistletoe lectin; neoglycoprotein; glycosylation; shielding; Biotechnology; Bioteknik; Pharmaceutical and related technologies; Läkemedelsteknik och relaterad teknik;

    Sammanfattning : Glycoproteins, a class of biomolecules, exhibit a variety of biological activities and therefore are of importance in modern biotechnology and pharmaceutical industry. Pure glycoproteins are needed for structural and functional studies. However, the separation of glycoproteins has been a problem until now due to their structural complexity. LÄS MER

  2. 2. New Arylation Strategies Based on Organomain Group Reactivity

    Författare :Carina Sollert; Lukasz T. Pilarski; Brenton L. DeBoef; Uppsala universitet; []

    Sammanfattning : The work in this thesis describes the development of new heteroarylation methodology based on transition metal-catalysed C-H functionalisation and the properties of organomain group compounds. The underlying reaction mechanisms and reactivity patterns of the (hetero)arene substrates are also investigated. LÄS MER

  3. 3. Responsive Molecular Systems through Dynamic Covalent Chemistry

    Författare :Antanas Karalius; Zoltan Szabo; Stefan Matile; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; stimuli-responsiveness; dynamic covalent reactions; systems chemistry; constitutional dynamics; non-equilibrium systems; nitroaldol reaction; dynamers; reversible polymerization; boronate ester; imine ligand; metal coordination; self–assembly; emergent properties; network topology.; stimuli-responsivitet; dynamiska kovalenta reaktioner; systemkemi; konstitutionell dynamik; icke-jämviktssystem; nitroaldolreaktion; dynamerer; reversibel polymerisation; boronester; iminligand; metallkoordination; själv-organisation; emergenta egenskaper; nätverkstopologi.; Kemi; Chemistry;

    Sammanfattning : Nature tends to inspire research in chemistry. Systems that emerge from molecules interacting via reaction networks is something that life has mastered over the course of evolution in order to produce complexity. Dynamic reactions are key in systems chemistry, where reaction networks give rise to complex, emergent behavior. LÄS MER

  4. 4. Transition metal-catalyzed allylic and vinylic functionalization : Method development and mechanistic investigations

    Författare :Johanna M. Larsson; Kálmán J. Szabó; Dennis G. Hall; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; palladium; copper; catalysis; Heck reaction; C-H functionalization; allylic substitution; silylation; borylation; trifluoromethylation; fluorination; mechanistic study; transition metal; alkene; allylic silane; allylic boronate; allylic fluoride; Organic Chemistry; organisk kemi;

    Sammanfattning : The use of small molecule building blocks in, for example, pharmaceutical research and new material development, creates a need for new and improved organic synthesis methods. The use of transition metals as mediators and catalysts opens up new reaction pathways that have made the synthesis of completely new compounds possible as well as greatly improved the synthetic routes to known compounds.

  5. 5. Carbohydrate-specific, boronate-containing copolymers: from sugar-sensing to cell adhesion

    Författare :Marina Kuzimenkova; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface grafting; chemisorption; boronic acid; carbohydrates; affinity; chromatography; smart polymers; biomimetics; hydrogels; molecular recognition; diffusion; sugar-sensing; cell adhesion;

    Sammanfattning : Carbohydrates play a major role in many cell recognition events and metabolic pathways of living organisms. Synthetic carbohydrate receptors are of great interest for the chemical design of sugar sensors, materials for cell separation, cell immobilization, drug delivery and other biomedical/biotechnological applications.
