Synthesis of precursors and studies of "click" azide-alkyne cycloaddition
Ivincová, Jana ; Zimčík, Petr (advisor) ; Roh, Jaroslav (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Chemistry and Drug Control Candidate: Jana Ivincová Supervisor: PharmDr. Petr Zimčík, Ph.D. Title of diploma thesis: Synthesis of precursors and studies of "click"azide-alkyne cycloaddition . Photosensitizers are used in photodynamic therapy that is based on a destruction of tumor cells by singlet oxygen. Singlet oxygen is generated during irradiation of photosensitizers. The third generation of the photosensitizers is characterized by high efficiency, optimal spectral properties and particularly by targeted distribution into the tumor cells. This can be achieved by conjugation of phthalocyanine photosensitizer with biomolecules. My thesis concerned with conjugation of suitable phthalocyanine with mestranol using 1,3 azide-alkyne cycloaddition (also called "click chemistry"). Selected photosensitizer with optimal photophysical and photochemical properties was prepared in our department earlier. 1,3 azide-alkyne cycloaddition is CuI catalyzed reaction of azide and terminal alkyne. This reaction is high yielding, selective and easy to perform, without any considerable effects of substituents in proximity of azide or alkyne. Pre-prepared 3-azidopropylamine was linked to the selected phthalocyanine...
