Valová, D.: Alkaloidy Vinca minor L. a jejich biologická aktivita III. Diplomová práce, Univerzita Karlova, Farmaceutická fakulta v Hradci Králové, Katedra farmaceutické botaniky, Hradec Králové 2020, 75 s. Alzheimerova choroba (AD) je progresivní neurodegenerativní onemocnění a je nejčastější formou demence. Vzhledem k tomu, že tuto chorobu zatím nelze kauzálně léčit, je důležitý výzkum nových látek. Tato práce se zaměřila na izolaci alkaloidů z extraktu Vinca minor L. jako potenciálního léčiva. Příprava a sloupcová chromatografie sumárního extraktu byla provedena Ing. Miroslavem Ločárkem v rámci jeho doktorského studia. Následná preparativní TLC vedla k izolaci tří sloučenin. Chemické struktury izolovaných alkaloidů byly objasněny optickou otáčivostí, NMR a MS analýzou a porovnáním získaných dat s údaji v literatuře. Jedna ze sloučenin byla stanovena jako (-)-vincin, zbylé 2 sloučeniny jsou nové (nebyly dosud izolované). Tyto sloučeniny byly také testovány na jejich biologickou aktivitu. Vincin, DV-1 a DV-3 byly testovány na schopnost inhibovat acetylcholinesterasu (AChE) a butyrylcholinesterasu (BuChE). Dále byla také testována inhibiční aktivita vincinu a DV-3 vůči prolyl oligopeptidase (POP) a glykogensyntase kinase 3β (GSK-3β). Všechny izolované alkaloidy byly téměř neaktivní vůči AChE a... Valová D.: Vinca minor L. alkaloids and their biological activity III. Diploma thesis, Charles University, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany, Hradec Králové, 2020, 75 p. Alzheimer's disease (AD) is a progressive, neurodegenerative disorder and it's the most common form of dementia. Because we're still not able to treat the cause of disease, searching for a new substance is relevant. This thesis is focused on isolation of alkaloids from a Vinca minor L. alkaloidal extract as a potential drug. The preparation and column chromatography of the summary extract were performed by Ing. Miroslav Ločárek as a part of his doctoral studies. Subsequent preparative TLC led to the isolation of three compounds. The chemical structures of the isolated alkaloids were elucidated by means of optical rotation, NMR and MS analyses and by comparison of the obtained data with those in the literature. One of the compounds was determined as(-)-vincine, other two compounds have not been isolated yet. Isolated compounds were also tested for their biological activity. Vincine, DV-1 a DV-3 were tested for their ability to inhibit acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). Additionally, vincine and DV-3 were also tested for their inhibitory activity on prolyl...
