Abstract

Biologická aktivita obsahových látek rostlin XXVIII. Alkaloidy vybraných odrůd taxonu Narcissus cyclamineus REDOUTÉ a jejich účinek na acetylcholinesterasu a butyrylcholinesterasu. JANURA M.: Diplomová práca, Univerzita Karlova v Prahe, Farmaceutická fakulta v Hradci Králové, Katedra farmaceutickej botaniky a ekológie, Hradec Králové 2015, Česká republika. Abstrakt: Sumárne extrakty alkaloidov z cibúľ N. cyclamineus cv. Jenny, N. cyclamineus cv. Little Witch, N. cyclamineus cv. Rapture, N. cyclamineus cv. Surfside, N. cyclamineus cv. Peeping Tom, N. cyclamineus cv. Warbeld a N. cyclamineus cv. Skater's Waltz boli získané obvyklým spôsobom pre tento typ zlúčenín. Alkaloidné extrakty boli analyzované GC/MS a bol sledovaný pravdepodobný výskyt jednotlivých alkaloidných látok. Tieto extrakty boli tiež podrobené stanoveniu inhibičnej aktivity na AChE a BuChE. Zvýšenú aktivitu na HuBuChE majú N. cyclamineus cv. Surfside s IC50 na HuBuChE = 61,26 ± 6,42 µg/ml a N. cyclamineus cv. Warbeld s IC50 = 85,43 ± 11,13 µg/ml na HuBuChE. Najlepšiu aktivitu na HuAChE má N. cyclamineus cv. Warbeld s IC50 (HuAChE) = 36,82 ± 4,50 µg/ml. Kľúčové slová: Narcissus, Acetylcholínesteráza, Butyrylcholínesteráza, GC/MS, Alzheimer's disease.

Biological activity of plant metabolites XXVIII. Alkaloids from selected cultivars of Narcissus cyclamineus REDOUTÉ and their influence on acetylcholinesterase and butyrylcholinesterase. JANURA M.: Diploma work, Charles University in Prague, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany and Ecology, Hradec Králové 2015, Czech Republic. Abstract: The summary extracts of alkaloids from bulbs of N. cyclamineus esp. N. cyclamineus cv. Jenny, N. cyclamineus cv. Little Witch, N. cyclamineus cv. Rapture, N. cyclamineus cv. Surfside, N. cyclamineus cv. Peeping Tom, N. cyclamineus cv. Warbeld and N. cyclamineus cv. Skater's Waltz were obtained by the procedures common for this type of compounds. The alkaloid extracts were analyzed by GC/MS and the probable occurrence of individual alkaloid substances was observed. These extracts were also assayed for HuAChE and HuBuChE inhibitory activity. N. cyclamineus cv. Surfside with IC50 = 61,26 ± 6,42 µg/ml and N. cyclamineus cv. Warbeld with IC50 = 85,43 ± 11,13 µg/ml have the best results in inhibition of HuBuChE. The best inhibitory activity on HuAChE has N. cyclamineus cv. Warbeld with IC50 (HuAChE) = 36,82 ± 4,50 µg/ml. Key words: Narcissus, Acetylcholinesterase, Butyrylcholinesterase, GC/MS, Alzheimer's disease.
