Amaryllidaceae alkaloids as inspiration for preparation of selective butyrylcholinesterase inhibitors I
Wisura, Matěj ; Cahlíková, Lucie (advisor) ; Kučerová, Marta (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Botany Candidate: Matěj Wisura Supervisor: prof. Ing. Lucie Cahlíková, Ph.D. Title of diploma thesis: Amaryllidaceae alkaloids as inspiration for preparation of selective butyrylcholinesterase inhibitors I The Amaryllidaceae family is considered to be very important source of biologicaly active natural compounds, alkaloids. These compounds are intensively studied because of their antiviral, antifungal, antiparasitic, antioxidative and antiinflammatory properties and especially for their ability to inhibit cholinesterases. This source is still not entirely depleted, which is proved by recent isolation of utterly new structural type of Amaryllidaceae alkaloids, carltonines, isolated form Narcissus pseudonarcissus cv. Carlton. Carltonines have shown promissing inhibitory activity of BuChE. Isolation of carltonines has become an inspiration for synthesis of highly selective BuChE inhibitors based on norbelladine structural type. This diploma thesis proceeds from pilot series of 20 compounds. During this study, another 21 compounds were prepared, expanding the portfolio and knowledge of structure-activity relationships within selective BuChE inhibitors group. Generated compounds were identified using NMR and ESI-HRMS....
