Chelating polymers for the therapy of Wilson's disease
Mattová, Jana ; Poučková, Pavla (advisor) ; Sedláková, Zdeňka (referee) ; Vávrová, Jiřina (referee)
Wilson's disease is a hereditary disorder of copper metabolism, which causes copper accumulation in organism, especially in the liver, kidneys and brain. Current treatment is based on using low-molecular weight copper chelators and high doses of zinc salts. Unfortunately, they can induce some severe side effects due to systemic action. The aim of this thesis is to improve the treatment of Wilson's disease by using of polymeric drug delivery systems. The size of polymer particles in tens of microns should provide non-resorbability of the drug after oral administration. Synthetic microparticles of poly(glycidyl methacrylate-co- ethylene dimethacrylate), natural microcrystalline cellulose and cross-linked chitosan were used as polymer matrices. N,N-di(2-pyridylmethyl)amine, triethylenetetraamine and 8-hydroxyquinoline were selected as specific copper chelators, which can complex copper cations with high efficiency. The principle of the proposed treatment is that the polymeric carrier-bound chelator complex copper directly from the food in digestive tract of the organism. Because of non-resorbability, the entire complex should be eliminated from the body together with stools. This virtually eliminates systemic side effects. The ability of adsorption of copper and the stability of polymer complex under...

Fotoindukovaná cis/trans izomerizace alkanthiolového derivátu azobenzenu zakotveného na Au nanočásticích
Dammer, Ondřej ; Pfleger, Jiří ; Vlčková, B. ; Procházka, M. ; Špringer, T. ; Sedláková, Zdeňka
Photoinduced trans/cis isomerization of -[4-(4-octyloxy-phenylazo)-phenoxy]-pentane-1-thiol (ABT) attached to geld nanoparticles was investigated in Au organosol/ABT system as well as on glass slides functionalized by gold nanoparticles.
Struktura a fyzikální chování termotropních polybutadien-diolů s mezogenními skupinami v bočních řetězcích
Jigounov, A. ; Ilavský, Michal ; Sedláková, Zdeňka
Liquid-crystalline polybutadiene-diols (LCPBD’s) with the comb-like architecture were synthesized by reaction of the LC thiol with the double bonds of the telechelic OH-terminated polybutadiene (PBD). The physical properties were investigated by differential scanning calorimetry and dynamic mechanical spectroscopy.
Botnací chování poly(N-izopropylmethakrylamidových) a poly(N-isopropylakrylamidových) sítí s náboji ve směsných roztocích voda/ethanol
Alenichev, I. ; Sedláková, Zdeňka ; Ilavský, Michal
Swelling behavior of negatively (ionic comonomer - sodium ethacrylate) and positively (ionic comonomer - (2-crylamidoethyl)trimethylammonium chloride) charged networks of poly(N-isopropylmethacrylamide) (PIPMAm) and poly(N-isopropylacrylamide) (PIPAAm) was investigated in water/ethanol mixtures at room temperature. Strong cononsolvency effect was observed for uncharged and negatively charged gels of both systems.
