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...
