This thesis contains the inclusion of solvent effect in the computational chemistry program MRChem. Water in water systems are of importance.

A group of molecules with the name diketopiperazines (DKP) are called so, because of their diketopiperazine ring as the core structural unit. Mainly there are 3 types of diketopiperazies which only differ in in the position of the keto group, one type has the keto groups in 2,3- position; another in 2,5-; and the third in 2,6- position. The 2,5- isomer has attracted great interest, because of compounds ...

Few studies have emphasized on the genus Aliivibrio as a whole and lags behind the better known Vibrio. Nevertheless, the Aliivibrio has for several decades been associated with species expressing bioluminescence like the Aliivibrio fischeri, but has also been linked to costly diseases in the fish farming industry such as Aliivibrio salmonicida. In an attempt to gain insight in the genus on a ...

The Breitfussins are a series of closely related heterocyclic compounds originated from the marine organism Thelia Breitfussi. The core is a 5(indol-3-yl)-2-(pyrrol-2-yl)oxazole, which has not been observed prior to its isolation in 2007. The divergence of the Breitfussins lies in the halogenation pattern and methoxy substitution. Breitfussin A is of synthetic interest because of its novel structural ...

dUTPase is an important enzyme in DNA metabolism. It can be thought of as a gate keeper for apoptosis and is therefore an attractive target when trying to kill malign cells which cause disease in the human body. dUTPase has been found to be an important drug target in diseases such as cancer and malaria, to mention two. Due to problems with drug resistance in existing treatments, the search for new ...

The work presented in this thesis provides an overview of molecular and structural biology projects and their related problems. The problems arises during these projects are common for most of the target proteins, with varying intensity of severity. The realization and identification of these problems and selection of their correct, best possible solution is an imperative step that might lead to ...

Recent work at the University of Tromsø has uncovered new α-substituted α- and β-aminoboron containing peptidomimetics that shows antimicrobial, antifungal and antitubercular activity in addition to kinase inhibition and promotion. As a continuation of this work a new approach for the synthesis of β-substituted β-aminoboronates has been developed. The approach involves the non-stereospecific ...

Kliniske studier viser at inntak av omega-3 fettsyrene EPA, DPA og DHA kan bidra til å forebygge hjerte- og karsykdommer, redusere inflammasjon, påvirke sentralnervesystemets funksjon positivt og bidra til en rekke andre helsegevinster. Som en konsekvens har markedet for kommersielle omega-3 produkter økt de siste tiårene. Det ble kjøpt inn 10 produkter til dette studiet. Produktene baserte seg på ...

The field of corrole chemistry has flourished over the past decade. Simple and high-yielding procedures have made the corrole ligand readily available, and several procedures on how to functionalize and otherwise modify corroles and their metal complexes have been reported. During an attempt to synthesize corrole from a fluorous tagged aromatic aldehyde a new porphyrinoid has been isolated from ...
