(Journal article; Peer reviewed, 2020)Multimetallic nanomaterials have many applications. The controlled synthesis of multimetallic nanomaterials is highly desired. We report a study on using penta-fold twinned (PFT) Au nanorods (NRs) as seeds to synthesize ... -
Synthesis of Some Nitrogen Heterocycles of Medicinal Relevance
(Doctoral thesis, 2012-04-18)In the first part of the project, two highly functionalized terminal alkynes, 3,3,4,4- tetraethoxybut-1-yne (TEB) and 1,1-diethoxy-but-3-yn-2-one (keto-TEB) have been used for the synthesis of 1,4-disubstituted 1,2,3-triazoles. ... -
Synthesis of substituted imidazoles that stabilizes Survival Motor Neuron Protein for treatment of Spinal Muscular Atrophy
(Master thesis, 2019-08-31)Spinal muscular atrophy (SMA) is a common autosomal recessive disorder and the leading cause of infant mortality. Patients with this disorder are missing the SMN1 gene that is producing 80-90 % of the Spinal motor neuron ... -
Synthesis, Characterization and Catalytic Applications of N-Heterocyclic Carbene Based Vanadium Complexes.
(Master thesis, 2022-05-31)New tri- and tetradentate O-functionalized NHC oxo- and imido vanadium complexes have been synthesized and characterized. The complexes were preliminary tested for catalytic activity towards coupling of CO2 and epoxides ... -
Synthetic studies toward [18F]-fluorination of solid-supported silyl ethers
(Doctoral thesis, 2023-05-25)Molekylær avbildning er definert som visualisering av in vivo biologiske prosesser på molekylært- eller cellulært nivå. Dette krever bruk av prober og kan gi anatomisk samt funksjonell informasjon. Molekylær avbildning ... -
TAT-Modified Gold Nanoparticles Enhance the Antitumor Activity of PAD4 Inhibitors
(Journal article; Peer reviewed, 2020)Purpose: Histone citrullination by peptidylarginine deiminases 4 (PAD4) regulates the gene expression of tumor suppressor. In our previously study, YW3-56 (356) was developed as a potent PAD4 inhibitor for cancer therapy ... -
Technetium-99 (99Tc) in the North and Nordic Seas – the present status (2010) and a compilation of the Institute of Marine Research’s monitoring data (2003-2009)
