Preparation of mitotic inhibitors in the form of nanotransporters
Meskařová, Veronika ; Indra, Radek (advisor) ; Hýsková, Veronika (referee)
Cancer is one of the most widespread diseases that every third person will encounter it. It is a disease arising from the sudden growth and rapid division of own cells. Despite progress in treatment, an effectiveness is not sufficient, and cancer is the second most common cause of death. In addition, the treatment is associated with several side effects. Currently nanomedicine uses nanomaterials for transport drugs in cancer treatment. It is possible to deliver the drug to the target site, but also to reduce the systemic toxicity of the drug by binding the drug to a suitable nanotransporter. This diploma thesis deals with seeking the appropriate mass ratio of antitumor drugs, colchicine and docetaxel, and the nanotransporter apoferritin. The aim was to find suitable in vitro conditions for high drugs encapsulation into the nanotransporter. Drugs encapsulation took place under active and passive conditions. Active encapsulation was under way on opening and closing nanotransporter by changing pH environment in test tube. Drugs were dissolved in DMSO or water with addition of HCl to charge the drug molecules and improve the binding of the drug into nanotransporter. As part of passive encapsulation, drugs were incubated in surroundings of urea or bivalent metal ions. Overall, it can be concluded that...

Nanoparticle forms of anticancer drugs and the mechanisms influencing their efficiency
Urbanová, Tereza ; Stiborová, Marie (advisor) ; Hýsková, Veronika (referee)
Currently, cancer is one of the major diseases of civilization. The disadvantage of conventional chemotherapy, which began in the 1940s, is its non-specific effect, so the cytostatics are toxic to healthy cells. However, if the cytostatic is inserted into a nanotransporter, it increases its specific efficacy and reduces the negative side effects. One of the possible nanotransporters is protein called apoferritin (a protein component of ferritin, an iron-carrying protein) that contains light and heavy subunits differing in their function in iron uptake. In this bachelor thesis, the ability of apoferritin to encapsulate two cytostatics (ellipticine and doxorubicin), depending on its origin and the proportion of light and heavy apoferritin subunits, was studied.
