Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Botany Candidate: Kamila Lipovská Supervisor: doc. Ing. Lucie Cahlíková, Ph.D. Title of Diploma thesis: Preparation of lycorine derivatives and their biological activity The plants of the Amaryllidaceae family are one of the most important sources of biologically active alkaloids. Lycorine, a phenanthridine alkaloid, isolated from various species of the Amaryllidaceae plant family, has attracted considerable attention due to its promising biological activities. Specifically, its anticancer properties have been evaluated in vitro and in vivo in various preclinical models of human cancers. Further biological effects manifested by lycorine are: antiviral, antibacterial, antifungal, antiplasmodial, anti-oxidant, anti-inflammatory and insect antifeedant effects, as well as ascorbic acid biosynthesis and RNA inhibitory activity. So far, lycorine was used for preparation of many derivatives by modification of different functional groups in its molecule, and screened for a various biological activities such as anticancer activity, inhibition of cholinesterases, antiplasmodial, antitrypanosomal, antiviral and anti-Trichomonas vaginalis activity. The present work deals with the preparation of lycorine derivatives and their...
