21. Peptide Conjugates as Useful Molecular Tools
Sammanfattning : The conjugation of a small organic molecule to synthetic polypeptides from a designed set has been shown to give rise to binders with high affinity and selectivity for the phosphorylated model proteins α-casein and β-casein but not for ovoalbumin. The small organic molecule that was used for this purpose is comprised of two di-(2-picolyl)amine groups assembled on a dimethylphenyl scaffold, and is capable of complexing two Zn2+ ions to form chelates that bind the phosphate ion.

22. Boron neutron capture therapy : Synthesis of boronated amines- and DNA intercalating agents for potential use in cancer therapy
Sammanfattning : Boron Neutron Capture Therapy is a binary cancer treatment modality, involving the delivery of a suitable boron compound to tumour cells followed by irradiation of the tumour by thermal neutrons. Boronated agents can selectively be delivered to tumour cells either directly with tumour-specific boron compounds, or by use of targeting strategies. LÄS MER
23. Theoretical Studies of Ground and Excited State Reactivity
Sammanfattning : To exemplify how theoretical chemistry can be applied to understand ground and excited state reactivity, four different chemical reactions have been modeled. The ground state chemical reactions are the simplest models in chemistry. To begin, a route to break down halomethanes through reactions with ground state cyano radical has been selected. LÄS MER
24. Amino acid transport and receptor binding properties in neuropsychiatric disorders using the fibroblast cell model
Sammanfattning : Altered transport of the catecholamines and serotonin precursor amino acids tyrosine and tryptophan, might be one explanation for the dysfunctional neurotransmission implicated in the pathophysiology of bipolar disorder and Attention Deficit/Hyperactivity Disorder (ADHD). In previous studies, an altered amino acid transport has been found in schizophrenia and autism, when using the fibroblast cell model. LÄS MER
25. Thiyl radicals, reaction kinetics and redox chemistry
Sammanfattning : In focusing on the free radical chemistry of thiyl radicals,two importantclasses are dealt with, namely, the amino acidalkylthiyl and the acylthiyl radicals, where pulse radiolysisand steady state γ-radiolysis are applied.Amino acid thiyl radicals (RS•), are important in manybiological systems,as intermediates in the repair reactions ofthiols towards targeted carbon-centeredradicals and ascatalytic centers in many enzymatic reactions.
