Diplomová práce, Univerzita Karlova v Praze, Farmaceutická fakulta v Hradci Králové, Katedra farmaceutické botaniky a ekologie, Hradec Králové 2015. Cílem této práce byla izolace obsahových látek ze sumárního diethyletherového alkaloidního extraktu z Argemone grandiflora Sweet, jejich identifikace a určení inhibiční aktivity vůči lidské acetylcholinesterase, butyrylcholinesterase a prolyloligopeptidase. S využitím chromatografických metod byly získány 4 alkaloidy, které byly identifikovány jako (+)- laudanosin, protopin, (-)-argemonin a (-)-platycerin. Tyto látky byly testovány na jejich inhibiční aktivitu IC50: (+)-laudanosin (IC50 AChE = 617,00 ± 46,55 μM, IC50 BuChE = 644,77 ± 55,52 μM, IC50 POP = dosud nezměřeno); protopin (IC50 AChE = 229,98 ± 21,02 μM, IC50 BuChE = 208,87 ± 17,67 μM, IC50 POP ˃ 1000 μM); (-)-argemonin (IC50 AChE = 4677,75 ± 1241,08 μM, IC50 BuChE = 885,45 ± 119,50 μM, IC50 POP = 337 ± 83,1 μM); (-)-platycerin (IC50 AChE = 223,65 ± 19,61 μM, IC50 BuChE = 1651,25 ± 327,7 μM, IC50 POP = 687 ± 74 μM). V porovnání se standardy galanthaminem (IC50 AChE = 1,710 ± 0,065 μM, IC50 BuChE = 42,30 ± 1,30 μM) a huperzinem A (IC50 AChE = 0,033 ± 0,001 μM, IC50 BuChE > 1000 μM)... Adamcová, M.: Study of biological activity of alkaloids isolated from Argemone grandiflora (Papaveraceae) I. Diploma thesis, Charles University in Prague, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany and Ecology, Hradec Králové 2015. The aim of this study was isolation of substances from total diethyl ether alkaloid extract of Argemone grandiflora Sweet, their identification and assessment of their inhibition activity towards acetylcholinesterase, butyrylcholinesterase and prolyl oligopeptidase. Using common chromatografic methods, four alkaloids were isolated, that was identified as (+)-laudanosine, protopine, (-)-argemonine a (-)-platycerine. These substances was tested for their inhibition activity IC50: (+)-laudanosine (IC50 AChE = 617,00 ± 46,55 μM, IC50 BuChE = 644,77 ± 55,52 μM, IC50 POP = not mesured yet); protopine (IC50 AChE = 229,98 ± 21,02 μM, IC50 BuChE = 208,87 ± 17,67 μM, IC50 POP ˃ 1000 μM); (-)-argemonine (IC50 AChE = 4677,75 ± 1241,08 μM, IC50 BuChE = 885,45 ± 119,50 μM, IC50 POP = 337 ± 83,1 μM); (-)-platycerine (IC50 AChE = 223,65 ± 19,61 μM, IC50 BuChE = 1651,25 ± 327,7 μM, IC50 POP = 687 ± 74 μM). In comparison with the standards galanthamine (IC50 AChE = 1,710 ± 0,065 μM, IC50 BuChE = 42,30 ± 1,30 μM) and huperzine A (IC50 AChE = 0,033 ± 0,001...
