1. 6. Development of Peptide Binders : Applied to Human CRP, Carbonic Anhydrase (II, IX) and Lysine Demethylase 1

   Författare :Jie Yang; Jan Kihlberg; Morten Grötli; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polypeptide conjugates; molecular recognition; peptide cyclization; protein targets;

   Sammanfattning : In this thesis, a polypeptide binder concept is illustrated. By conjugation to a set of sixteen polypeptides, a small binding molecule can evolve into a polypeptide binder with increased affinity and selectivity. LÄS MER

3. 7. Polypeptide Conjugates as High-affinity Binders for Proteins

   Författare :Lotta Tollstoy Tegler; Lars Baltzer; Amelie Eriksson Karlström; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein recognition; polypeptide conjugates; peptide; molecular interactions; C-reactive protein; Acetylcholine esterase; Human Carboinc anhydrase; Chemistry; Kemi; organisk kemi; Organic Chemistry;

   Sammanfattning : A novel concept for protein recognition has been developed. The recognition unit is a hybrid molecule obtained by conjugation of a small organic molecule to a synthetic polypeptide selected from a 16-membered set of 42 amino acid residue sequences. The sequences are unordered and have no prior relation to the target proteins. LÄS MER

4. 8. Polymer brush functionalised nanopore sensors

   Författare :Julia Järlebark; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer brushes; nanopore sensing; nanofabrication;

   Sammanfattning : Single-molecule studies on proteins could reveal a lot of information about their conformational dynamics, and processes such as misfolding and aggregation. This knowledge is valuable in providing a deeper understanding of molecular biology, and for understanding the link between proteins and various diseases. LÄS MER

5. 9. Development of catalytic enantioselective C-C bond-forming and cascade transformations by merging homogeneous or heterogeneous transition metal catalysis with asymmetric aminocatalysis

   Författare :Samson Afewerki; Armando Córdova; MICHELANGELO GRUTTADAURIA; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; asymmetric catalysis; transition metals; aldehydes; heterogeneous catalysis; amino acid; organocatalysis; α-allylation; β-alkylation; dynamic transformations; polysubstituted; carbocycles; spirocyclic oxindoles; all-carbon quaternary stereocenters;

   Sammanfattning : Chiral molecules play a central role in our daily life and in nature, for instance the different enantiomers or diastereomers of a chiral molecule may show completely different biological activity. For this reason, it is a vital goal for synthetic chemists to design selective and efficient methodologies that allow the synthesis of the desired enantiomer. LÄS MER

7. 10. Dynamic Systems for Screening, Control and Identification of Protein-Ligand Interactions

   Författare :Rikard Larsson; Olof Ramström; Michel R. Gagné; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dynamic combinatorial chemistry; Dynamic kinetic combinatorial resolution; Catalytic screening; Transthiolesterification; Thiol disulfide interchange; Nitroaldol reaction; Lectins; Hydrolases; Dynamic self-inhibition; Organic chemistry; Organisk kemi;

   Sammanfattning : Dynamic systems for screening, control and identification of different protein-ligand interactions are presented. Dynamic chemistry is used to produce new compounds/constituents in situ that can interact with a target molecule. Several entities can be introduced at the same time and interact with one another.
