New method of peptide separation using electrostatic binding
Palágyi, Attila ; Jindřich, Jindřich (advisor) ; Smrček, Stanislav (referee)
The diploma thesis deals with the development of a new method of synthetic peptide separation using electrostatic binding. It deals with the development of a multi-charged anchored linker attachable to a synthetic peptide after its synthesis on solid phase. Subsequently, it investigates the separation using electrostatic binding; however, after peptide cleavage from the anchored linker and Boc deprotection with TFA, the peptide formed so strong electrostatic interactions with the cation exchanger that we were unable to recover it. The thesis is finished with discussion and method improvement proposal. Key words: peptide separation, solid-phase peptide synthesis, SPPS, electrostatic binding

Cyclodextrin derivatives containing covalently bound volatile substances and studies of their release
Palágyi, Attila ; Jindřich, Jindřich (advisor) ; Smrček, Stanislav (referee)
The main aim of the work was to prepare a series of β-cyclodextrin derivatives containing covalently bound volatile compounds via an imine bond. The used volatile compounds were cinnamaldehyde, cyclamen aldehyde, lilal, benzaldehyde, anisaldehyde, vanillin, hexanal, heptanal, citral and 5-methylfurfural. Subsequently, the rate of the release of the active compound, as a function of the environment, was studied by 1 H NMR spectroscopy and static headspace-gas chromatography. Key words: cyclodextrin, aldehyde, imine, kinetics, controlled release
