Projektbeskrivelse
Introduction: The major obstacle to harvest the enormous potential of bioactive oligonucleotides is their delivery. The non-viral delivery of therapeutic oligonucleotides in low toxicity formulations is a currently unmet need. [1-2] In addition to the general delivery aspect, we aim to further developed our lipid membrane anchoring strategy for oligonucleotides to allow user friendly multiplexed formulation of lipidated oligonucleotides (LiNAs). [3-4]

Methods: We look forward to methods in organic synthesis such as chemoselective acylations, metal-organic reductions, asymmetric substitution patterns on chiral compounds with building blocks for automated DNA/RNA synthesis in mind. This project is designed for students interested to learn more organic synthetic chemistry with applications in classical and automated synthesis with focus on bioactive biologicals such as therapeutic oligonucleotides.
