Bio-inspired organic molecules for photodynamic therapy
Švarcová, Nikola ; Cigánek, Martin (referee) ; Krajčovič, Jozef (advisor)
Photodynamic therapy is a treatment method using the clinical application of photosensitisers for alternative treatment of oncological and inflammatory diseases. Using photosensitisers, substances with absorption properties, is a crucial element for the effective therapy process. Flavins can serve as photosensitisers in photodynamic therapy thanks to their conjugated system. The proposed bachelor thesis is focused on preparing of a novel, riboflavin-inspired flavin derivative. The structural isomers of riboflavin, alloxazines, provide simple synthetic modification for material properties enhancement. The theoretical part deals with the principle and mechanism of photodynamic therapy, modern trends in medical applications, limitations, benefits and essential elements for the effective therapy process. Consequently, the possibility of flavin derivatives potential use as infrared-absorbing photosensitisers is considered. The experimental part aims to prepare the intermediates and final precursors, 1,3-dialkylated uracil and acenaphthene-based 1,2-diketone. Verified synthetic paths described in the thesis provided high yields of the prepared intermediates and final precursors. Thus, the approaches will be utilized in the following synthetic studies to prepare the acenaphthene flavins series.
