  1. 1. Rational modifications of cell-penetrating peptides for drug delivery Applications in tumor targeting and oligonucleotide delivery

    University dissertation from Stockholm : Institutionen för neurokemi

    Author : Maarja Mäe; Stockholms universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-penetrating peptide; oligonucleotide; drug delivery; tumor targeting; MEDICINE Chemistry Neurochemistry; MEDICIN Kemi Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Abstract : High molecular weight biomolecules are becoming important in the development of new therapeutics. However, their size and nature creates a major limitation for their application – poor penetration through biological membranes. READ MORE

  2. 2. Cell-penetrating peptides in protein mimicry and oligonucleotide delivery Applications and mechanisms

    University dissertation from Stockholm : Institutionen för neurokemi

    Author : Henrik Johansson; Stockholms universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peptide; oligonucleotide; cell-penetrating peptide; PNA; splicing; MEDICINE Chemistry Neurochemistry; MEDICIN Kemi Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Abstract : The plasma membrane functions as a barrier, restricting entry of hydrophilic pharmaceutical agents. Cell-penetrating peptides (CPPs) are capable of transporting bioactive cargos into the cell and have consequently been extensively investigated for their mechanism of entry and capability to deliver various cargos spanning from peptides to plasmids.

  3. 3. Novel Methods for Synthesis of High Quality Oligonucleotides

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andrey Semenyuk; Uppsala universitet.; [2006]
    Keywords : Organic chemistry; oligonucleotide; solid-phase synthesis; RNA synthesis; phosphoramidite; abasic sites; depurination; 2 -O-DTM; protecting group; cartridge; conjugate; dithiomethyl linker; base-stable linker; oligonucleotide purification; nucleoside; Organisk kemi;

    Abstract : The first part of the work describes a procedure of oligonucleotide purification using a reversed-phase cartridge. The developed method employs a very efficient yet mild oligonucleotide detritylation on the cartridge support allowing fast purification of oligonucleotides regardless of their 5´-modification.

  4. 4. Specificity of antisense oligonucleotide derivatives and cellular delivery by cell-penetrating peptides

    University dissertation from Stockholm : Department of Neurochemistry, Stockholm University

    Author : Peter Guterstam; Stockholms universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell-penetrating peptide; splice-switching oligonucleotide; oligonucleotide derivative; MEDICINE Chemistry Neurochemistry; MEDICIN Kemi Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Abstract : Atypical gene expression has a major influence on the disease profile of several severe human disorders. Oligonucleotide (ON) based therapeutics has opened an avenue for compensating deviant protein expression by acting on biologically important nucleic acids, mainly RNAs. READ MORE

  5. 5. Complexes of cell-penetrating peptides with oligonucleotides Structure, binding and translocation in lipid membranes

    University dissertation from Stockholm : Department of Neurochemistry, Stockholm University

    Author : Luis Daniel Ferreira Vasconcelos; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptide; oligonucleotide; transfection; non-covalent complexes; membrane interaction; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The fundamental element of life known to man is the gene. The information contained in genes regulates all cellular functions, in health and disease. The ability to selectively alter genes or their transcript intermediates with designed molecular tools, as synthetic oligonucleotides, represents a paradigm shift in human medicine. READ MORE
