PharmDr. Petr Zimčík, PhD. Doctoral Thesis: Synthesis of photoactive derivatives of phthalocyanines and study of their biological activity Phthalocyanines (Pc) are macrocyclic compounds with conjugated system of double bonds with absorption maximum around 650 - 750 nm. They are characterized by high singlet oxygen production which makes them suitable candidates for photosensitizers in photodynamic therapy. However, they form inactive aggregates in water environment because of their planar hydrophobic aromatic core. There are many strategies to solve this problem, and this thesis is focused on fighting aggregation of Pc by their supramolecular interactions with cucurbiturils (CB). Subphthalocyanines (SubPc) are similar macrocyclic compounds composed of only three (instead of four) isoindol units with boron as a central atom, which has also axial substituent. Because of their cone-shape and axial substituent they are less aggregated in water but usually not very soluble, which could also be solved by interaction with CB. First part of this thesis was focused on synthesis of Pc with aminoadamantyl substituents on...
